Hi, I have connected my 3 position switch on my transmitter to Channel 8 input on the APM2 and have calibrated it as per step 1 {http://code.google.com/p/arducopter/wiki/AC2_ModeSwitch}  but when I toggle the switch, the modes do not change as in step 2.   Also, I cannot see "Arduapilotmega" in the drop down box - only "Arduplane" and "Arducopter2".   Is this normal?  Any help with this would be…
