I am configuring apm2 on my Zephyr2.  I have the throws down to about +-35% on my futaba9c.  In mission planner I configure, and then set the endpoints for each channel.  I save and boot up the plane…Continue

Michael Pursifull replied to Adam Haggerty's discussion Servos (channels 5-7) go silent after working for ~10 seconds
"It is customary to use one channel for flaps. Otherwise, they become ailerons. You always want them to move in sync. There are a few ways to reverse one of the servos, even without flipping it around.  You could use one of…"

Adam Haggerty replied to Adam Haggerty's discussion Servos (channels 5-7) go silent after working for ~10 seconds
"Ok I'll try to set aileron2 to channel 6.  Testing the manual mode now.  Is it standard to combine flaps to a single output and just invert servo mounting direction?"

Michael Pursifull replied to Adam Haggerty's discussion Servos (channels 5-7) go silent after working for ~10 seconds
"yes, it makes sense. However, you can change which channel the futaba uses for differential ailerons. I don't know of any other solution when using ppm sum, sorry. Maybe someone else does. "
