Hi,

I'd try widening the front to D/C firstly. You may also want to take off the in-board toe (so go to C/C). Also something worth trying would be to reduce the ackerman shim down to 3mm as they will take away initial steering.

Finally, I'd also say switch to a Protoform bodyshell, they're much more consistent than the HB.

Hope that helps!

I will try the C/C Blocks in front next time, but i allready reduced the ackermann and the car felt better with 4mm on Carpet!

Ive got my thicker chassis and topdeck today and will test it this weekend, then i will give a resume! ;-)

I cant use any other bodyshells than HB because its for the HPI Challenge and so you can only use LRP Tires, LRP ESC and Motor, LRP Adhesive and HPI or HB Bodyshells, and the Mazda 6 MPS felt best with the TRF417x so far!

I will also try different tire treatment with the adhesive before the heat...

Something positive is the fact, that the car is easy to drive and i think the thicker chassis will be better for high bite carpet, as the original combination is very soft!

Drove a Xray last weekend but it not felt as good as a Tamiya, but was a little bit faster...

So i will see on saturday, and then i will post my experiences!

You could try reducing droop a bit more to avoid traction rolling. (turn those downstop screws a bit further in).

Philipp1990 - You will find the thicker top and lower decks will help loads on high grip carpet, as the 7x is really designed for tarmac racing hence plenty of chassis flex in standard form.

Yes!!!

I drove it this morning and it was a awesome car!!!

But i found out, that the split blocks give the chassis more flex, so the car felt even better with the original 1piece blocks, not that much difference, but small changes can sometimes do a lot!

Also i was driving the kit combination of front suspension Blocks C-C, the car felt better and was easier to drive withouth that much initial steering!

Also the medium stabilizer rod in the rear was a few steps better.

The whole time the car didnt traction rolled and was way faster in corners and not that sticky as with the combination of 2,25mm chassis and 2mm topdeck!

So basicly it was the main basic of the setup, which marc rheinard uses.

Drove 17,5T today, will test the same setup with a 10,5T on Sunday!

Today i also tested the Tamiya Blue O-Rings and the Tamiya X-Rings for the TRF Dampers, the TRF Blue O-Rings leaked a lot and after two heats the dampers allready had a lot of air in it, so i decided to test the Tamiya X-Rings, a lot less leaking and smooth like the TRF Blue O-Rings, but after 4 more heats the dampers also had a lot of air in it...

I think you must rebuild the dampers often if you want to use the TRF O-Rings or X-Rings, so i decided to get back to the original O-Rings, so i rebuild it every morning before i drive and they keep smooth and air free the whole day!

My Setup is down below and a picture of my rebuilded car (im still in love! ).

Thanks a lot for your help guys!!!

TRF cars seem to be a limited to one production run. After the supply is exhausted, it's either A) make another run (if demand warrants it) or B) onto the next car!

I too think so, tried to catch a 417X for the last few months, and always out of stock on the usual places I generally buy.

Also parts, have a 416X that needed an upperdeck and waited for months too, but now managed to buy one from an user here at rctech.

Real shame if it is that the case.

I understand that the reedy 417x kit comes with a front geardiff now, but does anyone know if it still has the spool in the box?

Default What to do?????

I'm running my 417X on carpet using pretty much the stock setup only with gear diffs front (100K (have also tried 300K) and rear (kit fluid). I'm running it in a USGT class only with X pattern belted tires. I just put on a new set of tires which is when the problem started. With the old set the car just didn't have enough front grip... especially corner entry. It wasn't horrible but something I wanted improved. Now with the new set it is much better.. but... as the race goes on the rear gets looser and looser.

I have been wanting to try the Reinhard Reedy setup but haven't the time to put it on yet. Do you think that would help what I am experiencing over the stock setup. Or other suggestions?

Not for carpet...try a Jilles snowbirds setup as a base line.
