I am using the standard black shoes. They seem to be good for me. I have a Sirio engine and they hold up well. The other kind I have seen used in a GPX4 are blue and are softer for more bite.

Hi,
What brand are the blue ones that you use and does anyone use Teflon or Rulon or even a CRF clutch as I noticed the Serpent 710 CRF conversion looks the same.

Part #22159 - Blue SP centrifugal shoe

They are a bit on the soft side but work very well.

Hi Taffyjnr5, I am using the Hobao spring with not problem. If you think that's the problem squeeze the spring with pliers a few times and then try it. Check to make sure your brake is not applied when everything is installed. Maybe you have too many shims take a few out and try it.

Looking at your car it looks like you are using a different rear hub. Which one are you using?

Any modifications needed to get this to work, it's always good to know considering I have a friend that runs the RRR. It's always easier to bum parts from someone you know. LOL

Try making the clutch adjustment nut a little bit looser. Mine came from the factory WAY too tight. Car would just sit there and rev and go nowhere. Screwed it out a bit and off it went. Which reminds me, I need to readjust that, my starts are shocking.

For the people using the Hyper 12, are they getting many issues. Mine is the RTR so im sticking with the engine for a while. Mine is a pain to tune. The biggest problem is flameouts mid tank as the fuel level drops. So of course, when the tank is full, it's a rich running slug but slowly gets quicker as the fuel level burns off. Basically, I just tune it to last a full tank.

Has anyone here tried the Orion REV .12 engine in the GPX4 PRO?

Just wondering if theres any mods that need to be done, or special conciderations to take.
I know i probably must find some other gears to make it work on my local track which is fairly tight and technical. According to Orion this engine needs a lot higher gear ratio than other engines to work properly...

Cheers

Here's a picture of the main modification that improve a lot my car.



Put the mounting of the rear anti-roll bar inside the arm.
The anti-roll is harder and the car is better.
