Hey quinto73.
Go with the Tamiya TT-02. The HPI RS4 Sport 3 has a steering problem.
(Stay tuned. We're trying to work-it-out...Ha Ha!)

Thanks for the advice I could get a TT 02 model from 100-130$.

Default Major Steering Problem FIXED

I found the steering problem with the RS4 Sport 3. The problem is with the 2mm Pivot Block Spacers (item # 113710).
-Remove the Front and Rear Pivot Block Spacers and the chassis should run (fairly) straight.
(It could use a faster and stronger servo)

With the Pivot Block Spacers removed; the Suspension Arms will now be REALLY close to the Main Chassis (no-more than 5mm Ride Height).


Take Care

Default CVD driveshafts locking wheel

1st post. A newbie to HPI and road cars. (only RC experience is an Axial Wraith kit build).

I bought the car months ago, as well as the CVD driveshaft kit from HPI. Finally getting around to installing them. Once installed, both front wheels will not rotate. If I back off the wheel lock nut, things begin moving - but, it's backed off far enough that there's too much play.

In emailing HPI, I received: "This can be solved by fitting #72036 aluminium hex hub or sanding the rear of the plastic hub on 600 wet & dry paper so it is 5.4mm thick instead of 5.9mm as the stock width."

Anyone else had this issue? Should I sand or pony up the $20 for aluminum hex hubs?

Thanks!

(I spoke about this a few months ago). . .Sand the Wheel Hubs.
-If you install the Aluminum Wheel Hubs; you might have to place a Shim between the Bearing and the Hub. (it's work versus money)

Just drill a hole on each side of the chassis so the rocks fall out instead of wedging into the steering.

A picture with your post, when trouble shooting, will probably get more rctech help than without...

SWEEP the track before you run the chassis.

Thank you. To be clear, should I sand the flat side (against the wheel) or the more convex side against the chassis?

I didn't recognize the rear right suspension arm is bent(upward).
It had to come this way in the box.

Give this chassis a good look-over before you start the set-up process.

Hey Mike, Do you plan to design some new parts for Sport3? I'm pretty sure that HPI fans are waiting for decent aluminum pivot blocks, aluminum steering parts and of course aluminum motor support...

I'm assuming they're already designed as there are pics of actual prototype pieces out there. Just a matter of getting them into production. Until then, you could always try your luck with the GPM aluminum pivot blocks and motor mount...or use some already existing HotBodies aluminum pivot blocks.

If you are talking about the HPI items, I suppose the plans have been cancelled after the crisis...

I was not aware that GPM produces some parts. Thx.

HB parts are purple, dude!

It's only a matter of time until the rest of the HPI option parts are released. Right now they're focusing on straightening out the remaining financial issues and getting production of existing parts running again to restock HPI dealers inventory, at least the last update I read a couple months ago. Unless they decide to discontinue the RS4 Sport 3, the parts will eventually come.

GPM has a ton of aluminum parts on eBay for this chassis in several colors. Not sure if their QC has gotten any better though.

HB parts are purple, but they are direct swap and work. You can always de-anodize them and at the least make them silver. With a little more time/money or know how, you can anodize them yourself or send them out to be made orange or black.
