I guess you get what you pay for?![]

BUT, I only paid $18

I think I may have come up with a solution last night. With a shim made out of the included plastic for covering the wheel wells I seem to have it licked. I would estimate the shim is about 1/64 or less but makes the whole gear lock tight with very little play. I also doubt it will affect the servo at all as it does not touch until well past the servo arm throw. Hope to hook up the whole thing this evening and try it out. Keeping my fingers crossed.
