I have installed a S8R receiver in a model that has dual ailerons. Channel 1 is the right aileron and channel 5 is the left aileron. everything works fine when using the receiver as a normal receiver. When I activate the gyro modes (stabilization, level, hover, & knife) the left aileron (channel 5) does not respond to the gyro commands but does still respond to normal stick inputs. All the other channels do respond to the gyro. In setup I've tried checking the "Aux 1" box, "Aux 2" box and even both boxes. No luck. I've verified that the receiver has accepted the setup changes each time. Any suggestions?
