it appears that after my phantom 2 took the plunge that the controller is now bad. i am wondering what the difference is between the naza lite and naza m and stock controller? i am likely going to run in atti mode from here on out as i have had a few fly aways despite newest software and having the compass calibrated and my lights appeared to have full green lights with no red. i am considering replacing my controller with an upgrade..or if there is not much difference maybe the naza lite? thanks for your thoughts.
