I apologize in advance if this question has an obvious solution, but I'm stumped. I wired up my APM 2.5 with a Bixler 2 for the first time this morning and have been trying to learn my way around the technology on the bench. My problem is that when I throw the switch assigned to Channel 5, I can see the change register on the Flight Modes Configuration page... but the APM flight mode does not change, and remains wherever it was last set. The only way I can change it is by using the Set Mode option on the Flight Data page.
I'm using a FlySky FS T-6 transmitter and receiver and the 3DR GPS, power module, and telemetry kit. I've been testing everything via the telemetry link. The transmitter only has two-position switches, so I've assigned the Channel 5 switch to 1-3 Stabilize and 4-6 Manual. The APM is talking to APM Planner 2 just fine; the only problem seems to be with changing the flight mode.
Thank you in advance for any assistance.
