Default 8ight clutch help I think

I have a RTR 8ight. I was trying to run it today and it is acting funny. If you have it on the floor and push it. The car will not roll. So I tried to roll with the servo in the full throttle. And it will not roll. If roll both back wheels the car will roll the motor and it will try the turn over. So do you think it the cluch. I'm new to the nitro so I'm asking a simple but wierd question to me. I'm a electric guy so this is all new.


Please help.

If your motor is trying to turn over then the clutch has to be locked.
It could be seized bearings or locked in place shoes.
Hope this helps??

My next guess is I gotta take the motor out to fix it right. If it is just a shoe problem right.

Yep it's gotta come out. Pretty easy, take the screws out of the bottom of the chassis, loosen the grub screw holding the pipe on, take off throttle ballcup, and unplug the fuel tubing. I've not seen an 8ight but should be the same as everything else. Grab the flywheel with channel locks and take the screw out that holds in the clutchbell. From there it should be easy to see whats up be it a broken clutch spring or blown bearing. You can put a rag around the flywheel if you don't want to mar it up with the channel locks.

WOW. You need new shoes, and a new bell. Since you have it out, upgrade to 4 shoes instead of the RTR 2 shoes. It will increase the life of the clutch.

There are about 1.5 tanks through the motor and clutch. The buggy is not even broke in yet. This was done all at how Losi said to break the motor in at.

What clutches should I get. What springs?
I also planned on replacing the bell.

Should I contact losi and see if they would replace the shoes?

I would just get a new bell, and get the King Headz 7075 aluminum shoes with the Gold and silver springs.
