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.

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"?
Cheers,

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.

Nice job Frank,

Unusual to see holes in the front, Looks like it may of had a speaker in there for some reason.

Thanks guys.
Most probably the casings were used for AM/FM radios or walkie-talkies as well, like Grundig did with the Variophon reeds set.
