What clutch setup do i use with the O.S Speed engine? I think i need a realy soft setup, because now i just spin out the rear end.

And have any of you got the center diff lock up?
Mine locked up and when i loosen and retighten the screws on the diff it was fine again, but when i checked it after the qual. it was locked up again. so i changed to new diff gear. and it happend again.
But i fixed it by adding a shim under the pin on the outdrive on both end of the center diff.

I dont run a OS Speed, but i would use a 7mm restrictor and All carbon shoe's (i currently run a kyosho 3-shoe clutch) with 1mm spring's. It work's great for my Plus-5. But also factor in your driving style. What pipe are you using?

kjuliussen, I bet your center diff housing (the cup the gears are in) is shot. Open it up, pull the small gears and cross shafts out and inspect the slots that the cross shafts fit in. I bet the spots where the shafts sit are wollered out. Only fix is to replace the housing. When the center diff is locked up the car is a bear to drive. Fix that before you change your clutch setup.

Are you currently using the stock Losi clutch?

I will check that.. Thanks for the info.

But i did fix it with the shimming, but i'm going to try a new diff versus the one with the shimming and see if there is a difference..

i think it is green spring on alu shoes and black springs on the composite.
Or vice versa.

I just talked to a buddy who use's a Speed VZB, He said you really can't detune that motor. "It's mad fast" he refered to it. He said it's overkill for the 8, but if you want it in the 8 you gotta be smooth and run 20% in it. Hopefully someone else will have some idea's.

Stick with the pipe, It looks like a good universal pipe. You could probably find a good os Rg for as much as a new pipe. Just keep the Speed for large,hi traction track's.

I got a little dent in the pipe. the exhaust outlet is pushed a little back and in.
Do i have to replace the pipe or does'nt it matter?

Insert a phillips head screwdriver that is as big as the stinger, Then slowly pull the stinger back out. You might want to warm up the dented part with a blowdrier if it's cold.
