XRAY - Model racing cars

most of the brushless motors i have seen running make a different noise to what we have been used to for many years, if it is very noisy check to make sure you havent got a bent rotor, the last one i ran went noisy and blew up before i could slow it down.

HI
my car was noisy when i first got it and was a little dissapointed thougt it would be quiet and was running stock on small pinions ie 16 17 when changed to 19 t and larger 22 23 pinions it runs nice and quite till i go back to smaller pinions and the noise returns. im sure it is to do with the small amount of teeth. by the way i run rw spur and pinions. it may be this

cheers

yes, you can sometimes hear the gears wining if you use small thoot count
