just put my integy 55t in my tt-01 , it drifts tottally different as the cars speed is reduced ,its so much more controlable , using sushi drift tyres , also found when i had the car stripped down to put the motor in and to apply grease to gears my tamiya propshaft pins had slid to one side leaving a very short pin on both ends ,(i had had a slight vibration when using the car the last two times i have used it ) have tapped them back in place , has anyone else had the same problem , is there a fix anyone knows about , i was thinking supergluing them into the propshaft, sorry about pic best i could do ( not my prop ,just to show the pin i mean)
