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!!
thank you to read my post

here a picture:

0ne thing i forget to say it's writing 104 on that brown kind of chip

Those are two capacitors and i think they are for noise reduction on the receiver. You don't need them but you can de solder those ones and solder them to the new motor.

Hope this helps

Goodluck

They will not hurt your radio. The just absorb the electrical spikes produced by the motor

thank you very much guys i will resolder it to the 540 .
