DUH! Bit-Chargs are slow and if they had 5 turns it would prolly burn da motor up... But this is only from my 1/10 R/C idea... Cuz they usually have 27 turns and it goes way faster than a Bit-Charg, therefore i was guess the Bit Motor has more turns. Well you also have to consider da size of it... But I'll stay with my guess of 50 or more.
