Click for the new Blog, regular updates as to whats happening on the conversions front.

These conversions are based on a unique PPM encoder which when coupled to a 2.4g module, becomes a 'new age' Single Channel set.
These are generally available to anyone interested in building a S/C 2.4g tx - see the projects page and email Phil for details.
It accurately imitates a typical 1960s radio control set, with a few optional bells & whistles. This encoder makes it a simple job to convert any old S/C transmitter to 2.4ghz, and here are a few pics of some of our 2.4g S/C sets.
For the first one I tried to copy the look of the RCS Guidance System of the 1960s, whilst a 1967 GEM, looking suitably weathered, conveniently donated itself for another conversion.

Phil has built & supplied over two hundred S/C encoders now and its working really well.
It includes sequential or compound escapement emulation, using a state-machine software model of the Elmic escapements taken from timings in a 1965 magazine, it optionally drives an ESC for electric power, and has motor delay and slow-start for sequential rudder-only models, audio and visual warning of motor start, three motor run timers... silent mode (for gliders), the compound mode includes kick-up (or down) elevator, & quick-blip throttle... it has individual servo reversing, throw adjust, two range-test modes, config saved to flash, audio confirmation, 'next turn direction' cheat LEDs for sequential, - etc etc etc... and it also will drive a 'real' rubber escapement connected to the receiver via a channel switch.

Its all built on a neat PCB which has connectors for either a DIY hack module or direct insertion into a Futaba compatible module.
The PIC software is written entirely in assembler and we've been using Corona 2.4g DIY, Frsky DIY and several 'Futaba style' cased modules including Spektrum. In fact the 'Futaba style' module is Phil's preferred method now, as it does not involve any soldering to the module.
The encoder drives a simulator too, see the video below!

Its been a fun project, I've really enjoyed doing this one!

Typical conversion example using a Macgregor MR200:

The donor transmitter is carefully disassembled, and the 27mhz board saved in case you might want to reverse the process. Here, all the parts of the MR200 conversion are laid out - the side cheeks, aerial mount, front panel with its microswitch button and on-off switch, the emulation encoder and the DIY RF module with its bind board attached:
Heres the emulation encoder itself. The LEDs should be made visible, so in this case are bent around to mount through the front panel:
The encoder is mounted between the on-off switch and the button, using gyro-tape, which is a very strong double-sided tape. Clean the surfaces first with rubbing alcohol to ensure good adhesion. Note the LEDs protruding through the front panel:
Next, using more gyro tape, we mount the RF module and its bind-board. The back cover of the MR200 is designed to be easily removed, so its ok to leave the bind button inside the case. We then wire the battery and button connections to a standard servo plug, which then connects to the encoder header PL1. The RF module connects to PL2. PL3 is unused in this example, its an alternative mount which piggy-backs onto a Futaba-style module, thereby avoiding some of the wiring up. The aerial mount has to be slightly countersunk into the black Macgregor aerial mount:
The side-cheeks are refitted, taking care not to strip the PK screws in the soft plastic. A 2S 500mAh lipo sits at the base, connected via a JST:
And heres the completed conversion alongside the original 27mhz board. Result - all the fun of 1960's single-channel flying with none of the old reliability problems, no interference, no waiting your turn to fly, no running out of escapement turns... just perfect reliability!

Some more conversions:

Heres the new 'Tiny' reeds emulation encoder.



This is a true representation of a six-channel reeds set, without all that faffing about re-tuning the tones to the reeds every time!
This is just a prototype as I dont have a suitable donor set just yet, I'd like to find a 'proper' period six-channel set to convert such as
an Ariel Electronics, an RCS Sport-6 or even an Orbit-6 if one came up.

Phils recently converted Micron 'Elf' single-channel proportional set:


The 'Elf' is quite an unusual set in that it was a late arrival on the S/C scene and consequently Micron only sold about a hundred units.
It was sold as a kit for home construction, as can be seen from the advertisement.
This one was kindly given to me by Phill Wigley and had long ago been hastily refitted with the board from an Acoms 2ch car set,
the original Micron electronics lost. From that aspect it was ideal for conversion to 2.4g, which I've done using a Frsky DFT transmitter
module (in V8 mode) and a V8R4 receiver which is lost inside the original Elf receiver case!
The encoder is the Digimac 1+1 with the throttle button left unconnected.
This is a true recreation of the original set which was strictly single-channel, it drove one proportional servo with no option to expand.
The servo would typically be used for rudder in a model plane or boat.
Uniquely the transmitter didnt send PPM but instead was directly modulated by a standard PWM servo signal. In effect, it was
like a servo tester via an RF link. The AM, single-conversion 27mhz receiver had no decoder as there was only one pulse per frame,
and hence nothing to decode, its output a standard 1-2ms servo pulse.
After almost 45 years this set is again destined for the flying field, probably in a Veron Impala rudder-only slope soarer.
It would also be ideal for a small diesel or Babe-Bee powered S/C model. Far better it spends the rest of its days 'out there' than
on a collectors shelf!

Phil's 2.4g RCS Guidance System Replica
Shauns converted Macgregors & a Ripmax 'Pathfinder'. The older, larger Macgregor has a Corona 2.4 DIY module, whilst the smaller Macgregor & the Pathfinder use Spektrum modules and a 'piggy-back' mounted Single-Channel Emulation Encoder.
Phil's converted GEM Single Channel transmitter from 1967. Only the case and switches are retained - all the original electronics have been stripped out, and replaced with a Corona 2.4g RF module and the Single-Channel Emulation Encoder.
The heart of the project. A pic based encoder, written entirely in assembler, emulating the escapements and actuators of yesteryear. The software employs a state-machine model of the escapement, with a software armature, software pawls, software pawl stops... every aspect of the original is modelled, with one exception - the rubber never runs out! (I had even thought of including that option...)
The S/C encoder piggy-backed directly onto a 'Futaba style' Corona 2.4g module. With just a PP3 battery and a simple pushbutton, this makes a complete 2.4g S/C transmitter configurable for either sequential rudder-only (plus motor timers) or compound operation of rudder, kick-up elevator and quick-blip throttle.
The encoder Printed Circuit Boards
The encoder alongside a Futaba 2.4g module, note the connection pins.
The Macgregor Codamac and the Staveley S/C sets had a two-way switch instead of the button, and an inbuilt 'coder' which simply timed the pulses for left & right (well, only left really, right was just a push-on contact). This was to get around the requirement for fairly accurate keying of the old compound escapements. Instead of 'press, release, press&hold' for left, you would just push the lever left. For right, you'd push it right. For kick-up elevator, you had to press left then immediately right. The originals also included a quick-blip timer for motor control, again avoiding the need for accurate 'dabbing' of the transmitter button.

I've added an optional, enhanced 'coder' to the 2.4g Single-Channel arsenal and it works a treat, although I wont be using one as I didnt think it was cricket back then and I like the simplicity of 'the button' !!!

Here is the 'coder' board alongside the S/C encoder for comparison.

This gives selective right/left/elevator/throttle on separate controls by doing all the 'manual' pulse timing for you! The servos of course continue to replicate the movement of the old escapements, exactly as they do when manually keying.

Shaun's converted Macgregor Codamac Single Channel transmitter with the new coder as above, driving the standard S/C emulation encoder, which in turn drives a Corona 2.4ghz DIY module. None of the original electronics remain, only the case, joystick and button are retained in the conversion.
He's renamed the 2.4ghz version the 'Gigamac'!
The front-panel button is the throttle, and the red button on the side is a discreet kick-up elevator button, which the original didnt have - back then you had to do 'left' then 'right' quickly for 'up' so it wasnt that automatic!
Inside its fantastically neat, Shaun's done an outstanding job here.
It looks and works better than the original!
The 2.4g aerial, bind button & bind LED mounted on the top panel:
Phil's most recent conversion, a genuine period RCS Guidance System, converted using a Frsky 2.4g module and the S/C emulation encoder. The switch and button are the 40-odd-year-old originals and still work just fine. The case is a bit battle scarred, but its only showing its age!
Take a look at the video of this set flying a Tomboy 48:

S/C Tomboy maiden flight:

Phil: I recently bought an early 1970s Macgregor Digimac 1+1 transmitter for £14 on ebay. In its time this was 'half a step up' from the single channel radios of the period, having proportional rudder and a sequential 3 position throttle. It was popular for boats but a lot of model flyers used them too. The Macgregor electronics were not suitable for a straightforward 'hack' conversion, as it didnt use a conventional ppm stream, so I've written a custom 1+1 encoder for the same hardware as the single-channel emulation set. In practise it works exactly as per the original (the new s/w was written to the original spec) and its turned out to be a really nice outfit. This time I used a redundant Corona module and rx, although I might change that to Frsky (my favourite!) before flying it. For the moment the conversion isnt done that neatly, but it will be when I swap the module. With only rudder and throttle, the set only uses channels 1 and 3 of the 2.4g rx, but I've played a little trick with this one in that I have rudder on channel 1 but simultaneously reversed rudder on channel 4. This means that I dont need a reversing option on the tx, for different model requirements I just plug the rudder servo into receiver channel 1 or 4, whichever gives the correct rudder movement. Heres the converted set, does anyone remember flying one of these?
Here are a couple of internal pics. I've since converted it from Corona to Frsky using a 2-way module, set to V8 mode to match all my older receivers.
I tried a slightly different idea this time - its a Futaba-style module mounted edgewise in the case, with an RP-SMA extension lead (male-female) connecting the aerial. Its quite a rigid extension, hence the loop. Makes the layout a lot easier than trying to align the module with the extisting aerial hole.
The encoder is mounted on the side next to the stick unit, and theres a 2S 500mah lipo almost lost in the base.
Oh, the case isnt bowed, its a bit of parallax from getting the camera too close!

Here are a few photos of conversions done by friends, using the S/C Emulation Encoder:
Nigel's Modelectric 'Astral' S/C transmitter, fully restored and converted.
Chris with his RCS Guidance System which he converted to 2.4g, and his lovely Vic Smeed 'Chatterbox'.
Within days of ordering their encoders, Chris & Alans (below) S/C models were flying at Old Warden, attracting lots of attention!
Alan with his Keil Kraft 'Caprice' and A1 gliders, with home-brew 2.4g transmitter using the emulation encoder and a Frsky module.
Here's Alans email:
Hi Phil,
Yes, at Old Warden we flew them alright , Brilliant. and quite a bit of interest from club mates who remembered single channel. We were really impressed with the ground range of the Frsky 2.4 gig setup, 400m +!!!!
Chris flew his Chatterbox first and it was hilarious standing beside him and hearing all the frantic button pressing. On the gliders I have set up the kick up elevator function to operate the dethermalizer this is also set to operate on failsafe. I have been unable to fly the gliders free flight because they keep outflying the field. Now with S/C, I can keep them safe. We both look forward to seeing you guys up in Pontefract, we should have some more models by then too!
Keep doiní what youíre doiní, itís working!!!
Regards, Alan
Loyd G's really tidy Controlaire Mule II conversion. Loyd's Flydream Futaba module is mounted vertically just below the original aerial hole. Above the button are the indicator LEDs for rudder and throttle - Loyd says he's going to swap the button for a more positive microswitch.
Loyds email: "The encoder works great! I am using the FlyDream Futaba module. Here are a few pictures of my S/C encoder 2.4 Ghz conversion. I will clean up the wiring more when I get some tie wraps or something. I plan to add a charging jack too. I found out that I will need to find a better push-button also. The one I have works but it's not consistent. I don't want to admit that my thumb worked better 50 years ago!
Really....I envy your ability to program the PIC with so much information. I used to work on computers in the Navy about 35 years ago and had to learn a little machine language, so I think I know what you are working with. I learned enough to realise that I didn't want any more of it!".
Richard B's amazing Hinode conversion. Look how tiny the transmitter is!
No internal photos but it must have been a squeeze!
Richards email: "The photo is of the model I will be using with your emulator conversion, after a few test flights with proportional control. The model is a 1963 Aero Flash kitted by Airco Models out of Brooklyn New York, it is covered with OOO silkspan and the graphics were printed on a ink jet printer, nitrite dope with KlassKote epoxy for fuel-proofing engine is a Cox TEE-DEE .020 with a throttle sleeve. I'll let you know how the first flights go. Thanks for making these units available, it's going to be a lot of fun!"
John C's Macgregor conversion. Neatly done, and note his slide-in 'escapement' and receiver combination - just like in the 60's when flying a different model meant swapping the gear over first!
Johns email: "Please find attached some photos of my 2.4Ghz conversion of one of my olds McGregor sets, it all works beautifully, I just have to tidy up the airframe a bit and I'm going to fly it as soon as the weather lets me, the Pal Joey the radio is in was built in the mid 60's and has flown on and off up to the present day.
As soon as the reeds encoder is ready could you let me know, I haven't managed to get a reed transmitter to convert yet but if I can't get one it will have to be an old oxo tin or something, my old Astro Hog is itching to be flown on reeds, the Astro Hog is over 40 years old now and has a Merco 49 in it".
Doug's Macgregor - like an old friend given a new lease of life!
George's homebrew S/C transmitter, note the neat module fitting!
Gordon's homebrew 2.4g S/C transmitter. Aerial, switch, button. What more do you need?
Chris's old S/C Macgregor converted to a S/C buddybox. Note this has no transmit module, it plugs into his JR propo trainerport.
Please note that the JR/Spektrum trainerport version has firmware changes which re-orders the channels and inverts the PPM stream, and has a different PPM feed component, so specifically ask for the JR version if thats what you need.
Kevin's homebrew 2.4g S/C transmitter using a Corona Futaba-style module and a piggy-backed encoder.
This is Johns homebrew S/C set using a Frsky DIY module and the emulation encoder. The receiver of course is the standard Frsky item. Note the bind board mounting, the bind button is also used to select range-test power ona Frsky module.
Richards OS Pixie 2.4g S/C conversion, using an uncased Frsky Futaba-style module. Richard says a lot of planning went into squeezing it all in!
Note that Rich managed to get the encoder LEDs visible, which saves taking the case apart every time he wants to change the configuration.
And Shauns OS Pixie 2.4g S/C conversion, using a Corona DIY module. Both of these conversions are based on the 'new' style OS Pixie, which was a little larger than the earlier, more square-shaped version.
Its not quite so cramped as the Richards conversion as the Corona module is really tiny!
The only downside of the Corona is that you have to solder the aerial coax connections to the PCB, and theres not much room to work!
Peter's "Maplin Special" S/C transmitter, using a Frsky Futaba-style module. He's since made the LEDs visible - Peter reports: "After initially setting the system up it quickly became apparent that easy viewing of the LEDs would help, especially when changing set ups in the field without having to remove the case cover, as you say in your note. Having looked for a clear flanged disc to cement into the face of the case I found just the job. ALDI sell pepper & salt grinders with a removable clear cover. I decided to place the panel in the back of the case, as it is easy to switch the Tx on with the button pushed from behind. "

And a few photos of our own conversions done for friends, using the S/C Emulation Encoder:
Ali's Macgregor conversion - it had to be Spektrum, of course!
The cased module is a 'just fit', and 'only just' !
Ali's Ripmax Pathfinder, again using an uncased Spektrum module and the S/C emulation encoder
Ian's Macgregor conversion looking suitably 'weathered' and using a Corona DIY module. Ian specifically didn't want a cosmetic restoration, prefering the 'well used', 'period' look.
Inside Ian's Macgregor, bags of room for the Corona DIY module, bind board, the S/C emulation encoder, and half a dozen rabbits. Oh, and a battery!
Shaun has two RCS Comp 10 reed sets. The good one was restored to its original 1960s condition with all-original 27mhz electronics.
Here we see the other one, the 'beyond-repair' RCS Comp 10 which has been updated to 2.4g using a Spektrum DSM2 module and one of Phil's Reeds Emulation Encoder boards.
Shaun makes a really neat job of his conversions as you can see. Phil's prototypes were, shall we say, a bit untidy...
A close-up of the Reeds Emulation Encoder board, with a couple of the original RCS open toggle switches visible.
The encoder now has a smaller PCB with headers for the battery, switch, 2.4g module and one header per toggle switch. It can be built with up to 12 channels although this doesnt equate exactly since on a period reedset, you only had elevator trim and that needed two separate channels driving a separate trim servo!
It has progressive throttle and auxiliary channels, proper simultaneous servo-slow on all functions to match the speed of the old bonner Duramite reed servos, servo reversing throughout, trim on all channels as well as the standard elevator trim, (cheating, but why not?), and trims & reversing are saved to flash. It has a second aileron output (to avoid a Y lead), is fully simultaneous (of course it should be limited to bi-simul, but again... why not?). It also has a range-test 'sweep' mode for single-handed range checks. It incorporates the schottky PPM isolator for Futaba & DIY modules and has a trainer/buddy/sim output.
Its written entirely in assembler and it pretty accurately emulates the old reed sets of the 1960s.
The Spektrum DSM2 module fixed to the case top with the coax feeding the 2.4g aerial, with its power & PPM feed from the encoder.
And heres the finished article. Other than the aerial you'd be hard pressed to tell this apart from the restored 27mhz set.
This is Phil's converted 2.4g Remcom 12 Reed set, which arrived as an empty case (thanks Shaun!):
And heres an internal pic showing all six switches (12 channels) and the Frsky DIY module. Phil's conversions are not as neat as Shauns, but its a lot better than the veroboard original! The Remcon uses the last of the early (slightly larger) prototype PCBs. Notice the pot for the inbuilt servo-slow which selects the required servo transit speed
Phils converted Orbit 10 Reeds set. The final assembly was done by Shaun, he does them much neater than I can! It has a trainer port and a lipo alarm, and feels a lot nicer than the Remcon.
Here are a couple of made-up reeds encoder boards, these are slightly smaller than the one used in the RCS and Remcon shown above. Along the bottom are the connectors for the six control switches (each switch is two channels in reed-speak) and at the top is the battery, switch and buddy connector. The latest version also has a header near the buzzer for the servo-slow speed pot. You need a lot of servo leads to wire up one of these!
Johns converted REP Quadratone, now on 2.4g using the Reeds emulation encoder and a Spektrum DM8 module. John has added the additional toggles to upgrade it to the REP 'Decatone' ten-channel set. A really neat conversion, note the use of an RP-SMA extension lead for the aerial. The servo transit speed pot can be seen between the toggle switches. The set is destined for Johns original 1970s KK Super Sixty, he says "until I get my hand back in flying reeds, when I have it is going to be used to fly some of my old 1960's aerobatic models, the first aerobatic model that it is going in is my Gee String which was designed by Bob Palmer in 1961 or 1963 to fly on reeds".
Hopefully John will be sending more photos as the plan progresses!



And a few videos:

Please note that this is an old video showing an early version of the encoder software. Since then the escapement transit speed has been increased to match the original Elmic specs (see next video), and the sequential/compound slection shown here has been replaced by a comprehensive setup mode. Throttle now has an option for 3-positions rather than just high/low.
The video shows Phil's 3/4 scale Veron Impala, with RCS Guidance System replica on compound rudder, kick-up elevator & using a spare servo to demonstrate the quickblip throttle.:

The Single-Channel Emulation Encoder plugged directly into a Spektrum module, demonstrating compound operation:

A prototype sequential Single-Channel Actuator Emulator connected to an old 27mhz Macgregor and a Towerpro micro-servo:

Virtual flying - a Single-Channel Emulation Encoder driving FMS in a realistic demonstration of a typically hairy S/C flight:

The 1967 Gem S/C set converted to 2.4g using the S/C encoder:

Demonstrating the optional coder, which does all the button-pushing for you - cool, but its just not cricket!



Here's Phil's Sharkface flying at Ponty Park.
It uses a HET Typhoon 3D motor on a 2S 800, and the converted 1967 GEM 2.4g Single-Channel radio.



And here it is at last. Phil's 2.4ghz Reeds Emulation prototype in a Junior 60 at Pontefract Park, on his Birthday!



Vic Smeed Poppet on rudder-only, flown at Pontefract Park, on the 2nd Feb, 2012:



A little bit of an indulgement, here's Phils recently converted Skyleader Clubman - new encoder and a Frsky RF module.


The Skyleader conversion story is here.



Feedback is always appreciated.

Here are a few nice reports from S/C Emulation Encoder users:

Hi Phil
Find attached 2 photos, the 002 picture is of the four SC models I have tried so far all flew really
well and my button pushing is improving. I think I am a sequential man at heart but the temptation 
of elevator and throttle is stronger than common sense at the moment although I do struggle with
quick blip. The 005 picture is the next 4 models to be tried although I think the Willard Top Dawg
may have to wait a while yet. I also will have to improve my lash up of a TX which does not do justice
to your excellent module, just waiting for a nice period TX to come along but so far no cigar. 
I did mention I would try the Debutante out first but the weather has been rather windy so 
"proper" SC were used instead. I have several other models to try out which I have built during the
nostalgia sickness of the last few years (I think the treatment is working now!)which are Madcap,Coquette,
Chatterbox no 2,Schoolboy,Impala and the Wizard of Oz gliders. 
I think there may be more but I am ashamed to mention them. Sorry there is no video yet but I hope
I can work on that. Finally all the models have flown before but as normal 2 or 3 function aircraft
and hence were all trimmed fairly well, the next step would be to trim a SC model from scratch....
WOW life in the fast lane eh!!!!
All the best, Glyn    


Hi Phil,  the Skyskooter flies great on rudder only, I'm going to add kick up (or down) elevator 
tomorrow morning and have another go if the wind dies down. I've just received another 
Corona receiver and I'm busy putting it in my Veron Deacon, I previously had the Deacon on my old 
Fleet radio with just rudder and elevator but never felt right flying it with a propo tx, it will be much 
nicer to fly with single-channel on rudder and kick up or down elevator, I want to fly this and the Skyskooter 
at the free flight Nats at the end of this month, I've flown my single channel stuff down at our 
flying field quite a bit in the evenings and the modellers who have recently come on the scene 
or even the ones who started flying after single channel had been superseded, 
just can't believe how a model can be flown with just a rudder and look gobsmacked when I occasionally 
make a perfect landing on the runway, brilliant stuff, thanks.
Regards, John.


Hi Phil,  my encoder arrived very soon after the 19th march.  I even had time to try the system out
in a KK Gyron and it worked really well and wow it was fun!!! even the throttle worked well on the brushless 
motor and I could flare the model out on landing with the KU elevator (well sometimes). 
Thank you for developing the system and although I originally wanted to use escapements
how nice it is to know that the servos will not drop out on long signal holds like escapements were 
prone to do. I will report back to you when I try out the other models 
(Chatterbox and Debutante)
Many Thanks 
Glyn      


Hi Phil, the encoder works a treat, built it into a plastic box I bought 
from maplins. Wired it up to a frsky DIY module in the end, all very interesting. 
Might try it in a mercury matador or junior 60 eventually. 
Anyway thank you for the encoder and all the best with any future projects. 
Barry


Phil , received your encoder today all working fine within 5 mins,just need to build a plane now !! 
Thanks for all your help
Kevin


Phil,
I must say I am astounded by the speed the professional manner in which you responded 
to my inquiry.  The PayPal funds have been sent, you should see them shortly.
I received your encoder last week.  Thank You!  It seems it only took about a week which surprised me.  
Anyway, I've already assembled it into a working transmitter.  I used a Corona Futaba compatible module and it works great.  
I'm going to have fun with this thing!
I am attaching some photos of the transmitter I made.
Thanks again,
George


Hi Phil, just to let you know that I have now flown my old Pal Joey with the 2.4Ghz converted 
McGregor single channel Tx, it all worked beautifully and I had about half a dozen flights in the afternoon, 
that's the way to fly old models, just as they should be, single channel, I'm now busy fitting some more radio 
into my Veron Skyskooter, I'm having three position throttle and kick up elevator on this one, I'll send some photos soon.
Rgds, John


Well, today was the day. After a short break of just 463 months I carried out my first flight using compound S/C.
My home made Tx utilising one of Phil_Gs encoder performed faultlessly........unlike some of my flying (twas ever thus ).
So pleased with the first sortie I pressed on with a second mission. Flying improving, but undershot strip due to 
overbanking the final turn which allowed the nose to drop too far and bust the prop on impact landing. 
No other damage. New prop fitted ready for tomorrow.
T'was funny in that, when I offered to hand the tranny round they all shied away? 
Gordon


Hi Phil,
Parcel was waiting for me when I got home as promised - thanks very much, I am very impressed with everything.
Built up my first set in one of the smaller MacGregor transmitters and works great.  I've attached photos of my new 2.4 set. 
If anybody is tempted to try the 2.4 single channel route, but is a bit wary of building one, from my experience I say go ahead,
it is really easy and great fun.  
I used one of Phil's emulator boards with a Corona DIY module. I converted an old MacGreogor single channel transmitter.  
Took me just over an hour, and I have only basic soldering skills. 
If you can wire up an ESC or servo extension lead you can build this.  
If you don't have an old TX to convert, you can get a universal component box from Maplins, 
which I am using for my second TX - they still look really good.
I had my first flights last week with a Blunderbird, powered by a DC Merlin . 
After a few retrimming flights (slight change in CG after removing RCS RX and compact escapement) 
I had a ball. One of the best afternoons flying fun I have had for ages.
Next model nearly complete is a Swannee - going full house on this, kick up elevator and quick blip throttle.
Cheers 
Doug

Hi Phil,
Built and tested on a 7.4 lipo battery delighted with it looking forward to test flying it intrest in model flying gone up 10 fold.
Sent pictures of the transmitter.
Many thanks
John.

Phil, I put the 2.4 single channel goodies in an old 1960` era Controlaire Mule transmitter and every thing works fine. 
Now if I can get it in an airplane maybe I can fly it. Thanks so much for all of your help. 
A couple of pictures enclosed as attachments, hope they come through.
Regards,
Floyd

Hi Phil,
Your board arrived safely a few days ago.  A couple of nights ago I dug out my favorite single channel transmitter,
an F&M Echo, and converted it to 2.4G and your encoder.  Worked like a charm the first time.  
I decided to hardwire it rather than use the servo plugs/headers.  Will send a photo next time I have the camera out.
Friday evening I went out to my club field, and after doing final checks and ground range tests, blasted backwards
into the Nostalgia of Button Pushing.  While the two flights I had were successful, there we moments of stress. 
My escapements were faster than your Elmic units, as most trials to get up-elevator ended up with left rudder.  
On the ground I could do it, but in the air old habits and timing took over.  
Rather than continuing to risk one of my favorite "hot" rudder-elevator aerobatic planes, I have decided to build a trainer 
out of an old wing and tail from my basement archive.  I will feel more comfortable retraining my thumb on an old drub.   
I don't know how many of your units are on this side of the pond, but you have at least one happy and grateful customer !
Take care,
Keith

Hi Phil,
I just thought I would pass along the results of my first S/C flight in 50 years.
I used a Ken Willard Pageboy. That is not the easiest thing to try it with. I had way too much power and it climbed like crazy. 
I could not get the motor(electric) to cut off. I was not blipping fast enough to activate the motor servo. 
I replaced the switch in the transmitter with a better one and then did some "ground" flying (without the plane) to get 
accustomed to the right timing for the blip. Everything worked good. On the second try, a week later, I trimmed the glide first. 
I put a smaller prop on to decrease thrust, added down thrust and left thrust to the motor and had 2 successful flights. 
Now i just need to do some fine tuning and it should be just fine.
I have attached some pictures of the little Pageboy. 
I just started construction of a Midwest Tri-Squire and I'm really look forward to flying it.
Cheers,

Hi Phil 
As I have now maidened my Lil'T would you like a couple of images for the S/C webby?
This has been my first S/C flat field type glider for .....(oh sh_t!) just under 40 years! 
Mind you it flies 10x better than I remember my last effort ever flew.  
Next up on the S/C menu for me is maidening my Impala on the slope and building a S/C motor assisted (E) glider. 
I keep looking at both the Slinky and Moonbeam as the next slope glider.
I have yet to try my hand at sequential but will do on the Timber.....Recently worked out I have had over 100 S/C flights on that now! 
I was taken aback by that. But I do find it enjoyable to pole about the sky bashing the button.
Best Regards

Hi Phil,
Flew Sharface today in sequential mode. Its probably 45 years since I flew single channel, but it was like riding a bike! True nostalgia without the disasters. Iíll try to find a suitable camcorder man for some flying footage, Iíve also located a Mercury Matador for some rudder only work.
Regards,
Peter
