Enabled PPM output in configuration, then soldered a wire via 1k resistor to Port1 from atmega pin according schematics of 4ch/6ch receivers, attached it to the ppm configured arduplane autopilot and reaction to sticks is inadequate.
When I do full right with stick - then servo moves to its limits.
It moves only on full input, and nothing between center and full input.
Looks like it lacks something to work properly.
I am afraid you need to do a bit more than load RX firmware on the TX.
firstly which TX unit you are hacking ?
