The issue I'm having is that the throttle control on the plane (a micro super-cub) is mapped the aileron stick on the transmitter. This is with the normal default channels on the tx. When I turn the anylink on and try to get it to map into the "alternative channel map" mode, I'm supposed to get 3 beeps but I only get two & it never goes to the alternate channel mapping. It's pretty much useless in this configuration. What could the problem be?
