estimated life of zz motors
 

can anyone give a ballpark figure of how long they think a zz motor will last. i have had my nos motor for about 2 weeks and it is clearly slowing down. should i return it or what.

my engine did the same about 2 days ago i had to get tweasers and a toothpick to clean out the hair out of the engine and its workin fine now

good call on the hair, i just cleaned it out and its back to normal. thanks for the tip

i think they last a while...if not they are still pretty cheap:)

Same here. The dirty axel problem and weak batteries seem to be the only thing that slows these things prematurely. The motors seem to last forever if you don't slap too much juice to them with tri and quad cell mods. They are really high quality coreless motors. Better than I thought would be offered in these relatively cheap little cars.
