ohh yeah and about that prop, whenever i take the prop off of the shaft the motor runs fine. it is a 12x6 on a 6.6:1 but i got a prop and kept cutting it down until it was about a 2 inch diameter and it still didnt work. but if you spin the prop really fast and jump on the throttle it works fine. do i need soft start? my batteries were fully charged.

thanks for the replies
