I have raced both the CD3 and the GPX-4 and my preference is the GPX-4 as it seems more of a stable car and much easy to drive fast.

In my experience i have found i have been quicker with a shaft drive car, but everyone to there own.

Problem is there is no real good shaft drive option at the moment that is a reliable choice out of the box IMHO...

Default side tensioner not lining up
my side tensioner does not line up with the belt. it actually pushed the belt towards the outside about 1 1/2 mm. i seen some other pics here and it looks like others are lining up ok. here are some pics of my bracket. is it machined wrong ?? is the aluminum shaft with the hex suppose to be flush with the outside of the bracket or is it suppose to be recessed. or what did i forget ??

put a shim behind the rear pulley and it should line up perfect, It will aslo get rid of side play from your 2 speed shaft when fully assembled.

does anyone have a good setup for the gpx4 yet? I have the RTR version if that helps. nice car I can see it being fast once the setup is right

I am looking for more rear traction right now the car wants to loop out almost like a drifter where you still have control but are losing time.
