I’m having trouble with automatic flap deployment during takeoff and landing. I have my flap servos on RC9 and RC10, set to flap_auto (3), and my flap input from the transmitter is coming in on channel 7. Manual flap control works fine in all modes. I have tried LAND_FLAP_PERCNT at both 0% and 100%, and TKOFF_FLAP_PCNT at both 30% and 60%. None of these settings seems to deploy flaps during automatic takeoffs (hand launches with the motor running prior to launch) or automatic landings. A log file and config file are here:

During the flight, I brought the airplane into auto mode, which powered up the motor but did not lower the flaps. I brought the flaps to 50% manually for launch, and retracted them manually after launch. During the first automatic landing attempt, the flaps did not lower so I lowered them manually, and retracted them incrementally during the landing abort. I did not touch the manual flap control for the second landing attempt, until after the aircraft was on the ground and I did two quick full flap extensions to check for manual control.
Interestingly it appears that both the C7 input and the Ch9 and Ch10 outputs have a slight movement at the beginning of both landing sequences, but it’s only changing the output by 100 uS. I was definitely not moving the flap control at that point. Any ideas? I’m flying a pretty slick airframe and the flaps are necessary for accurate auto landings.
