Hello - still a bit new and have a question.

I have an Mcx that begins to fly erratically - after 1 to 2 minutes of flight I lose control - especially the ability to rotate clockwise.

I have tried any of 4 different batteries, charged the batteries with 2 different chargers and and checked that all shafts are tight and no gears are stripped. I have also ensured that the transmitter and charger have strong batteries. I estimate the little bird has about 150 flights.

My best quess is that I have a motor that is failing but I know little about how they fail. Second guess is that all 4 batteries are failing simultaneously - I use them in rotation - and know little about how Li-Pos fail. Third guess is a transmitter failure but this seems unlikely.

My brute force solution is to order new motors and a new battery - try the battery and then the motors.

I would appreciate any advice from your collective wisdom.

Thanks muchly.
