The TX uses an X1TX0 r/f board extracted from a Spektrum DX4e transmitter. This is a full-range board, unlike the 'park-flyer' X10EMTX board I used in my previous TX but is programmed in exactly the same way (using the serial output pin of the Arduino). The KAP controller also has a Hover switch, since my new EOS M rig has Hover capability (a first for me). It also has a 5.8GHz video downlink (another first).
The page has downloadable wmf plans for the transmitter box and rig, as well as a downloadable Arduino 'sketch'.
