ok… so most RC receivers have a three wire interface… signal V+ and ground. The FlyPOD has FOUR!!
On the ‘PRO’ the case is not marked as to the pinouts. The Flytdocs say (left to right) 5VO - R T
what is t he fourth pin and whi9ch should the radio be plugged in to? The the power supply OK to power the radio? I’m assuming 5VO would be the normal radio V+, the - the ground, but would the signal FROM the radio be the R or T? (and why a 4 terminal non standard i/o to begin with??)
