Not a bad idea Yar Genius!

Thanks, vc05hdt, yes I'm using Team Orion CRF 2626 and these are tuned for high r.p.m. range like what Shocker have stated.

I still using the default 0.8module 16/20pinion and and 43/47 spur...is it to make it faster when using 60/56T?

A very nice car! I'm glad you were able to resolve the clutch issue. Definitely pick the brain of the racer who fixed your clutch. Hands on experience is the best way to learn new aspects of your car. I'm glad to read that your engine has improved for you. If you decide later to swap engines, at least by then, your comfort zone and experience driving the GPX4 Pro would make a transition to a faster engine no problem. Now, does your GPX4 Pro out perform your old Cen CT4 ?
Note to vc05: John's pipe is an Orion CRF exhaust, and these are tuned for high r.p.m. range.
Regards
Thanks Shocker, I will change to Nova Engine sooner or later...yet to compare with my old Cen CT4 as I broke my shock shaft and carbon front bumber plate when trying to get 2nd speed...btw I just found that Cen car is using .15 engine... yet to try it out with my new FM radio with powerful servos...sanwa (throttle servo) sx-165t is 0.09sec 9.7kg (steering servo) erg-rz 0.07sec with 8kg. Will change to 3pk when I feel I need more control...

Actually I broke mine once ...will consider to put the default plastic below my 2nd carbon plate to make it stronger...Thanks for your great idea.

Hello from France,
here's my GPX4 Pro.



My car weighs exactly 1700grs , ready to race (with four little diameter tyres, the body, the personnal transponder, and without fuel).

I like this car.

Hi

What has happened to your Tamyia? And how do you find the belt drive GPX4 compared to the shaft drive?

Yes on tight technical track I think with lower top speed and quicker acceleration.

One of my mentors suggested using Nova carby with Hyper 12. Has anyone else tried as supposed to fit straight in. Sounds like would work well as adjustment low speed needle unlike stock Hyper carby? I will try it as have spare Novarossi motor in shed when get the chance. John Tan where did you get the Orion CRF manifold and pipe? Good price?

I switch to GPX4 because of my sponsor.

Here's a link I've already gave.
A presentation of my car.

Bonjour Romuald, I see in your set up sheet that you use gear diff in Pro car with 100k oil and not one way diff in front. What are your tracks like to run that combination?
