this is my 1st post, on this website, and I am hoping to be able to contribute as well as get answers, I have been into rc vehicles for almost 3 years now I have approx 8 or 9 rc vehicles, depending on the status of my sons. I will update my profile when I have some time, I have an important matter regarding my Hyper 7 PCR .
When I put the buggy on the starter box, and start the buggy, my clutch engages and the wheels spin, with the flywheel? I have to jam a screw driver down in between the diff and clutch bell to keep it from spinning, a few times it has then some how worked correctly? I picked this buggy up of ebay, a few years back, and have just recently begun to run it again. when i got it it was very clean, but seemed like there was something odd about it, I swear, i would be driving it and it would run and drive forward then it would just kind of buckle, and then stop moving, engine would continue to run, then when back on throttle it would move BACKWARDS!!! I told the guys at my LHS, and they just nodded their heads, and smiled....

\I dont know if they were trying to hold back the laughs,or the bull&%* remarks, but i am being honest, I have removed the clutch bell, and I cannot tell if the springs and shoes are correct, the car didnt include a manual, my yokomo gt4s, has the Centax, all others have only two shoes and one spring that latches to itself around the shoes and the clutch nut, for the buggy there are three small springs inside the shoes, is it possible the clutch shoes are installed backwards, or the springs are installed wrong, or do they need adjusted or are they simply worn out? can i remove the springs off the clutch shoes, or are they somehow, installed wrong? oR do i have to add some shims to the inside of the clutch bell???
any advice would be great, or if I am totally off base please let me know, thank you in advance...
