I'll check it out. I do pull the prop check them both once in a while( MH dual setup) but maybe one's dragging or something. Hey, Gary; can I buy parts from you for the V3? I can't beleive they broke,front mount only, cold out though. It usually takes the frame at the mounting post with it. Superglue ain't working. Last time i broke one was 25+ MPH into a baseball backstop. they sure do screw when you turn them loose outside, HUH? PS. What elecs do you have on that df4 vid from your site?.......Mule
