Beta Version 3.5 r8 (quadcopter, X-configuration) is loaded. We need to this version because we have a TeraRange Tower 8 installed. The Tower 8 seems to be working.
However we cannot arm det to a Pre-arm error; Firmware_Frame Type error. We tried disabling Pre-arm check, and that did now work. Anybody have any ideas on how to resolve the Pre-arm error?
