hi everybody i am a newbie here and i don't speak english well excuse me for it .
ok here why go so i got here 380 electric motor from my aerobird 3 from hobbyzone and the thing is i want to change my motor for a 540 motor coming from a clod buster ,sorry again i search my words again . ok so the thing i know is the aerobird extreme came with 540 motor and the receiver is the same. but when i look on the back of my 380 motor i saw some chip or a resistance and i want to know what is this because my 540 motor doesn't have it and is it dangerous for my receiver . if somebody can save my life now i will appreciated!!
