So, to compliment my 4 channel transmitter I made last week, I thought a twinstick 3 channel would compliment it, designed in the same syle.
3d printed case and laser engraved front panel cover. 3rd function is just a switch, ok for a motorised Impala or the like, where just on/off motor is required. Throttle safe is incorporated so the motor will not start until the switch is cycled at switch on plus the usual warning tones.
I fitted the only meter I had to hand which was taken from a scrap Futaba M-series FM set. Wired up for expanded scale battery voltage using the tried and trusted Zener & resistor method, I think it looks ok,
Last photo shows the 4ch & 3ch side by side for comparison. Charging sockets on both are a 3 pin JST-XH on the rear with a swivel cover to protect.

Great way to use sticks from old transmitters.

As I often ask Tobe, don't you sleep much.
