Single Channel Replica Transmitters

[tiptipflyer]

Hi guys
the next replica transmitter is finished.
It is a Futaba FT-3A replica.
It features one of Phil´s S/C encoders with all the bells and whistles.
A rocker switch for power is located on the side.
HF is provided by a Futaba style Jamara 35MHz module. Power is from a PP3 style 2s lipo.
The enclosure is 3D-printed. Works great.

Cheers

Just finished the 2.4G brother to the Futaba FT-3A transmitter.
This one uses Mike_K´s new S/C encoder. Works great.

Some time ago, I saw a nice, tiny Hinode single channel transmitter in the internet. I like all tiny things, so a replica had to be build.
And here it is. The case is 3D-printed and measures 80x45x38mm, so it is tiny, just big enough for an Orange 2.4G module, an Attiny85 and a PP3 2cell lipo.
It uses the S/C sketch with additional throttle button I am using in several other projects.
It features compound and sequential mode, sequential 3position throttle, inactivity alert, low voltge alert etc.
Works very well and fits in a pocket, but nevertheless a full range transmitter.

Superb Frank on the FT3-A
Frank, Just an idea
The button on yours looks like grey plastic, I was thinking the chrome end cap on a old fuse might just fit over the top, I'm presuming the original was chrome, it looks like chrome

Thanks guys.
Ron, you are right, the button on the black transmitter is indeed an endcab of a fuse, the button on the FT3A is 3D-printed Pla.

A pair of new transmitter replicas is ready to go. Both cases are 3D-printed incl. the Minitron logo on the front.
First is a S/C O.S. Minitron in gold. Digispark with S/C emulation and extra throttle button for sequential throttle. Inactivity buzzer, low votage alert. 35 MHz module.
Second is a blue S/C proportional O.S. Minitron. I added a button for S/C emulation incl. kick-up elevator plus progressive throttle like the GG trannies have. Inavtivity buzzer, 35MHz module. All on a Digispark extended to use P5 with Phil´s fuse programmer.
Both are working great, but not flown yet.

Cheers

Very nice!!

Frank, where do you get your meters from as they are most realistic? Am I correct in assuming that the center loaded antenna coils are 3D printed "dummies"?

[tiptipflyer]

Yes Wayne,
the antenna coils are dummies, the meters are salvaged from old Futaba transmitters.

P.S. Flight-test done this morning, everything worked out perfectly as expected.

During bad weather, I drew some enclosures in OpenSCAD for new replica transmitters and get them printed.
That´s what they look like. The cases are still empty, just the switches are installed and decals attached.

So stay tuned for further.

Excellent job Frank.
