Smoking motor (How to know if its the gear or the motor ?)
 

Im trying to transform my old & poor Crossman NightProwler SA.
BB counter, digital hopup level display, new spring, new motor, painting... Just for Fun !

BUT before upgrade i need to fix. The motor is rushing. everytime i pull the trigger, a bb is shot and the motor make smoke and smell the rushing motor. So i received my new motor today and have the following question:
How to test if it is not my gearbox that make the motor rush ?

I dont know, maybe i need to turn the first gear that the motor turn and if i cant do it because it's so hard it mean this is the problem ? I dont know!

Help me please ? :)

Displamer: Remember when i said "just for fun". It mean i dont need a gun doctor, either a brand new airsoft. Just sayin'

Vas-y en français, tu utilises ce qui semble être un anglicisme que je ne saisi pas (motor rushing).

Un moteur qui force lÃ* ... Sa sent le moteur qui force ... (+ de la mince fumée)

Est-ce que tu as essayé le moteur hors AEG pour voir s'il se comporte correctement?

Je me sent ridicule ? Je vais essayer ...!

PS. Don't try to hold it in your hand and turn it on. It'll fly out of your hand ;)

You must have some pretty weak hands! I can hold onto a motor just fine when testing it.
