I almost finished assembly my F450 with APM 2.6 and have 2 question before i go to the filed.
1. Should i made a first flight with GPS or without it? GPS have a compass onboard. It will be mounted on stand pole so if i crash/flip it will be destroyed... Maybe for first flight i should mount it without stand pole? It is possible to made a flight without compass in stabilize mode?
2. I use 3dr power module. Should i connect the batt to the power module and then after locking everything connect power module to the PDB? Or i have to connect everything at once?
Thanks for the any help.
