Default Clutch Bell disappeared???

Uhhhhh, it's in the title. I was running the car, and I hear some extra revving in the engine. I kill everything. Come to find out, the clutch shoe, carbon clutch shoes and bell are gone. Just like it was ripped off. I have to replace all of them. I can't describe it, i'm going to take a picture of it and post it.

It must be on the tracks somewhere. Could it be the Hex screw wasnt secured and worked itself out while running? Check cltuch bell gar so that it is not too much otherwise when the shoe kicks it kicks too hard.

Also look at your thrust bearings, I dont run any btw.

Default PRP XR-8

I had the same problem with my XR-8
The aluminum clutch bells are prone to go bad.
Mine actually split in two.
They do have an upgrade clutch bell that works really well.
I put one on, and have not had any other problems.
You might want to also change the flywheel, fly weights,disc, and clutch pad.
I used all Mugen parts, and everything is working fine now.

Did you use the complete mugen system?

the mugen stuff are indeed hardy but instead of shifting to all mugen I replaced the clutch bell for a ventilated serpent item and it worked great.

How to post pix? there must be an add attachment button somewhere, it's on the same page.Hope that helps.

Was wondering what steering servo's are you guys using. I am on the VX 13kg's and thought it could be an overkill, the VX's saps power from the Rx batteries.

Default PRP XR 8

I am using the Airtronics 737 for the throttle, and the Airtronics 358 for the steering.
I changed over the to the 7 ring conical header,and the 9886 pipe.
Also the front pully has been changed to the Delta. It is aluminum, and holds up great.
I am off tho the track right now with mine, but when I get back, I will take some shot of the car with the body off.
These cars are also prone to on-power push, but I found that if you use the Mugen front springs, 50 wt oil, and then use the Serpent body, the car really sticks well..
It took me about 3 weeks to get the car to where I wanted it, but I have not had to change the set-up at all, other than changing the tires for the track condition

I also noticed the push you mentioned but only when the front wheel are really worn down. I am still running the stock grey spring F/R with 40wt oil and Protoform shell.

Try the Mugen white springs, with 50 wt oil.
It should help take out the push.
Also if you go to the PRP web-site, look under XR-8 on the right side of the page, scroll down, you will see the set-up sheet used for Fort Myers in Florida.
I use most of that set-up, and then modified it for the track I run on.
