I have an rvjet with px4 and the old endurance package(Frsky radio, x8r rx) and noticed the huge adverse yaw at low speed and also want speed brakes. The way I figured I can remedy this is by using two servos, one per wing, that operate two controll surfaces each and create drag (like duckerons, but not part of the roll system, only yaw and speed brakes). I want the pixhawk to counter yaw using these two channels and to deploy speed brakes too. Is this doable or am I chasing rainbows?
Much thanks!
