same way as hpi's tutorial says.
now i only have 1 of 4 trucks with the plastic spur.and the picco. .28 should have shredded it by now but its been good.

Status: offline 		change your clutch springs the originalls are too loose and engage at a low rpm hence heating up the clutch bell and melting the spur. i have installed losi lst2 shoes and springs and havent had a melted spur since (16.00 at a-main for clutch springs and shoes)

Status: offline 		thanks for the help. I was wondering how to get my savage to wheelie. I have installed a 3 speed and allthough it is very snappy I think it would be crazy to get it up on two wheels!!!
