MP 1.3.44 quad, copter, just updated: (I have done this before with non-PPM setup on an APM2.6 on a quadcopter):
When trying to use PPM from my FrSky D4R-2, sent from my Turnigy 9x:
In the MP INITIAL SETUP - RC , I can see Ch 5 and 6 hitting all 6 different PPM rates, between ~1125 to ~1900, when I toggle GEAR and Func N-1-2 (I have 3 mixes setup in my 9x, that are right in the middle of the PPM ranges for each flight mode).
However, when I go to MP CONFIGURATION _FLIGHT MODES I only see the Channel 5 PPM signal (for the 9x this is the 2 position Gear switch). I move the 3 function switch at this screen and nothing happens for setting flight modes. Yes, I know channel 6 is not to be used, and I have it INH in my 9x Tx setup (only Ch 5 is set as Gear). I go to the config/tuning expanded setup and set all 6 flight modes, but they don't work...
