HPI RS4 2 problems.

[JDMPollo813]

hey guys i have a hpi rs4 2 with a os18cvr with is a bump box motor. I'm having a problem with it running right now. i recnetly just put a new 1st gear spur gear and got done putting back all the crap together. i put some nitro in my tank and take it outside to run it. well, when i had it on the bump box, it started like normal. BUT when it does start it makes a PING and when the ping happens the car jump foward as if i acclerated. and it likes to cut off when this happens. anybody have any suggestions?

Sounds like it's clutch related. Check the bearing on the clutch bell, and make sure it's still in good shape and rotates freely. Also, check your clutch shoes and springs, and that there is no debris in there keeping one or more shoes from disengaging fully.

Wait a sec, check your 2 speed one way bearing first. If it worked fine before you tore it down, I bet it's in backwards.

On my car (RS4 Racer 2) I installed the HD 2 speed. And on mine, if you are holding the car with the trans facing you, when you push the tranny gears forward (towards the front of the car) it engages and drives the wheels. When you push it backward towards the rear wheels, it doesn't and is disengaged. Hope this helps man
