installed clutch basket today. 2 HD pads in basket , 1 standard pad behind spur. Yes , instant power , my truck has never done a wheelstand on concrete before , now it does . I know this isnt a trick that translates to a useful tuning tool for the track but I can see the difference in rear wheel traction straight away. practice day this saturday so I will be putting a heap of packs thru it and cant wait . here is my local track http://youtu.be/nTZ3EWXtNc4 this was a 1/8 nitro meet and the 1/10 cars dont use the back straight , as you can see , big , fast and dusty ! the sc10 4x4 on this track is an absolute screamer ! thanks again Mac for a well designed and functional product .
