I'll share a W-Boyz tip with you. You still may have some gearing options, if other spurs can be fitted. We have "the magic number", for our conversions where the motor can't move. After you lock your motor down, find that perfect pinion that meshes with your spur correctly. Add together the number of teeth in the spur and pinion, and once you have the total, thats your "magic number" for that rc. Any spur and pinion combo that adds up to that number will go on, without you having to move a thing.
