I am using a used ninja mr 21 with a p3 plug and the stock losi clutch set up. I preheated the motor and started it on the bumpbox and it fired right up. While it sits on the bumpbox the wheels turn good and fast but when i get it on the ground it won't break 10 mph and sounds like its revving good but there is no speed. At first I thought it might have been a dif problem so i removed the motor and rolled it around and it rolled smooth with no sounds of grinding or whining. But when i put the motor back in its real jerky and makes a little bit of a whine. I set the gear mesh using the paper method, so I know its not too tight. My current clutch setup is 4 aluminum shoes with 2 silver springs and 2 gold springs. Any tips/help would greatly be appreciated. I live in lancaster and was planning on running at XRC a little this year if any local people were willing to show me some pointers at the track since I am new to the racing scene. Thanks.
