No problem. I'm still playing with them. I always ran #5 and 60 wt. in front and #3 and 50 wt. in the rear. Not 100% sure about the new setting yet. Seems the best with the setup changes.
Let us know what you come up with.

take care

Just had a thought. If I remember right, your running stock aren't you? I'm running mod. Not sure if that will make a difference or not. You probably want a little stiffer dampening.

Hey guys, have any of you used the Square input shafts for the pro 4? I just got a set and noticed that the shimming is waaaaay different than the kit shafts. I was able to back off the mesh up front, but I'm not happy with the rear input shaft. Any suggestions? I think RCZ uses these, but I could be wrong.

Gary....I have one in my car. Just play with the number of shims until you get it to feel free. I think I might only have 2 of the suggested 3 shims or 1 instead of 2 but I know that I ended up with one less then what it shows in the little picture that comes with it. Unless you can read chicken tracks(joke) Im not sure what else to tell you. It takes some time to fool around with. I took the rear gear box off and played with it until I got it to what I liked.

K, that's pretty much what I thought Kevin. I'll play around with it then. I may end up taking out one of the purple spacers and using smaller shims just so I can fine tune it better

Default Probably Already Asked but....

Does anyone know if HPI will have the new arms available in the US soon? Also on the BMI chassis set should I do the upper deck mod or not? Any help would be appreciated.

what is the diff tween new arms and old arms?





i would suggest the upper deck mod, because it isnt going to hurt anything, and it gaurantees that you wont have a tweak problem.

the new arms are made of a different material making them more flexible... this is perfect for outdoor asphalt racing..

Default Just a few questions...

does HPI or somebody make a very short stub (2inch) hex driver to get the motor screws out?

How is it getting the motor out?

Can you reach the screws from the rearend?

Removing the diff covers, is it as easy as a TC4?

A 2.5mm ball driver is best for getting the motor screws in and out. The screws are not impossible to get at with a normal driver but are quite awkward. I think Hudy make a 60mm 2.5mm driver.

To remove the diff covers you need to take more or less the whole top deck off, then 2 other screws, pop the top links off and remove the nut from the shocks. The process is a little long-winded, but it doesn't really take that long to do.

My car also seems to have a lot of play in the steering, it seems to be coming from the steering plate and the bearings, I wonder if there is any way to stop this??

Try different brands of ball cups. Some brands are tighter (not binding) than others, this will probably be the biggest source of the slop.

A little slop is good though...
