That's what I thought too. When I have nothing else to spend money on, I'll probably get one.

Rob, what difference in steering did you notice when you went to the forward hole on the steering? A lot quicker response?

Thanks and take care

Wassup guys. A very good friend of mine just sent me an HPI PRO4 to blueprint for him. The car will be run on carpet in 19t class. I see there are over 200 pages of info here, but wondered if anyone could highlight any weaknesses of the car, and let me know what i may need to change on the car to make it fast and bulletproof on carpet. Do i use the one-way, as i have no problem, but do not prefer, driving a car with one, or do i swap it out for a front diff? I know that answer will vary from driver to driver, and car to car, but i have run a TC3 since the day it was released, and a one-way is a no-no in that car. Any help will be greatly appreciated!!

90% would say no one-way, but depends on the track somewhat....

You can mod TC3 carbon shaft to fit PRO4. A lot cheaper this way.

I tried to run a oneway last weekend on our new carpet track and the car was driveable but not consistant. It tried to overrotate mid to exit. When I tightened the car up it pushed then. Without spending days on setup I dropped the diff in it and the car was much more consistant and you could navigate traffic with no problems. There is a track about 3 hours away that swear by a oneway on their track but it is a tight track so it is needed. I agree with Tres. It will depend on driver and track conditions but most of the time the diff will be the better option.

Which front drive: Diff / One-way / Spool?
*Diff, oneways rarely work on carpet. Everybody tried spools a year or 2 ago, but most ppl went back to diffs.


As far as the width thing, the car had all around more steering, and rolled through the corner much better. Kinda felt like it was a compass pointer, and the rear end was the pivot point. As far as Hara widening the front end on asphalt, I can understand that. On carpet, you're usually trying to add corner speed and steering, since the cars are so stuck. This is kinda the opposite of asphalt, where you want to make sure the car will not loop out, and also be stable enough to run a 7t.
Thanks for the info. .

Rob, what difference in steering did you notice when you went to the forward hole on the steering? A lot quicker response?

I was trying to get the inside wheel to turn more. i had built extensions for the knuckles on the advice of Downforce at the carpet nats. This was definitely better than the stock position, but when i had more time to evaluate it, that really wasn't the best solution. KevinK wanted to try the forward hole. He said they always ran a similar setup on the Schumacher cars, and that was really good. So we tried it. i think it lessens the outside tires throw, but gets the inside tire turning more. It's more about getting the car to roll thru the corner via reduced ackerman than response. Eric S may come on here and say I'm nuts, but it looks like the best compromise now. But seriously, give it a try.

I believe ceramic bearings would possibly make the car quicker. Ceramic diff balls would make the differential smoother, improving handling and power applied to the wheels.

Default nitride bearings

nitride bearings won't make it quicker. they are just smoother....are they really neccessary though if the diff just comes loose all the time anyway?

i'f got a box full of parts with these balls.....still haven't broken anything to justify the cost of parts! think i might drive the pro4 WOT into a curb to justify these parts i can test the prp chassis while i'm at it
