I have trying to configure my Walkera F12E transmitter to use it with the Phantom 2, i am using a signal converter module since the Walkera doesn't have SBUS and the P2 flight controller only takes SBUS receivers. Anyway in the P2 software i have set a switch as the flight modes switch, but when i toggle the switch it just changes between the Failsafe, atti and the mode you can chose yourself all the way to the right. The problem is that the when i toggle the switch it doesn't go all way to the left to GPS, so in other words i can't chose GPS mode as one of my preferred flight modes since the switch aint going all the way there. Does anybody know how to change that so it goes all the way to the left to GPS? Also i can't start the engines with the start engines command, and not by any other stick kombination either? I guess this problem is not specific to Walkera but can happen with Futabas and other brands as well. Help would be much appreciated.
