Default CHEVRON G350GT SHELL

Hi
Has anyone ran this shell on their Pro 4?
I've just finished fitting one and it took some getting the rear down to a decent level ! - I am at the bottom hole on the rear body post and could really do with a lower hole!

(Sorry about the Associated springs, just the only ones I have heavy enough )

Check out the back of the manual for the tuning options. Pay very close attention to how your car has traction entering and leaving the corners and adjust according to that. No need to settle for a bad handling car. If you can't figure it out, ask!!! Everyone here is willing to help

Tires depend on your carpet. A good startin point is Plaid (Purple/Orange) front tires, and Purple or Pink rear.


take care

Thanks, JohnB and Tres

as for my question. okay for example a 180 degree turn. while entering the corner about the centre racing lane, the car is fine and stable turning in. but while exiting the corner, the car is taking a wide turn/or should i say understeers. how do i go about fixing this?

maybe my braking point is too deep into the apex. and i'm taking wide turns out. by the way, i'm using a one-way on carpet.

any help would be appreciated greatly!

6* of caster bro---- 6*!!!

Also, ditch the 1 way. That is the first step.

Actually, why don't you post your setup, and then we could try to help further.

I would suggest picking up the xxx main book also. It is truly awsome. It is categorized to make everything very easy to find, and it list situations of what your car might be doing and how to fix it.

Like HuDy WiNnEr said. the XXX Main setup book is great.
For instance, you push under power, according to the book try this:
Stiffen rear spring
Thicker shock oil
Outer hold on rear shock mount
stiffer rear sway bar
more negative front camber.
increase front kickup
reduce front droop
increase front roll- lower roll center
etc, etc.

There is whole column like this for each situation. The rest of the explains in detail why each adjustment does what it does.

take care
john

The Aero 2 is really good also, I have never tried it, but from what I have heard it is really good!

My set up works really good with the PF Stratus also, so it should work with the Hpi body also, just give it a try!
Hi Again Eirik
I was rebuilding my car last night and was putting your setup on to try tomorrow and I had a few probs getting some of the settings... maybe you can help how u do it?
1.)How do you centre rear hubs? Seems the spacers are 0.75 and 2mm and I have other 0.75 but can't get to fit.
2.)Says rear pivot block spacers 2.2mm ... I assume use one 2mm block but what you use for 0.2
3.) I see you change the ackerman position and flip the steering plate round .. can you tell me what handling effect this does.

Otherwise rebuild going well and I can't wait to get down to the track to test all these settings

Cheers
Scott

Acutts,

#1: To center the hubs I just used some smaller shims, but you could just use the bigger spacer in front and the small one towards the rear. The difference will be really small....

#2: I used 1pcs 1mm, 1pcs 0.5mm and 2pcs 0.7mm Purple spacer for the camber links (one on each side)
It will be easier to just use the 2mm spacer and a 0.2mm washer if you have one.....

#3: Using accerman position #3 will give you less initial steering, makes it easier to drive.

Please let me know what you think when you have tested the set-up!!!

I spent around 100 packs trying different things with AMB lap counting and this set-up gave me the fastest lap times!!

Are you going to WLRC for your testing?
I was there last year for the BRCA Nationals, nice track!!

Cheers mate!

Thanks Mate ... will complete the build tonight and then I am probably testing tomorrow night or maybe Thurs depending on weather at my home track (Tolworth). Then I am racing this weekend in the KO GP at West London ... it is a nice track.
Big race Sat (Testing) Then Sun (Qual) Monday (Finals).

That Excel carbon part for camber links. Do you need to order 2 or are there 2 in a pack? There is no pic on RC Model.

I bought the delrin pivot balls a while back so have installed those and they feel good. Doubt they will make any performance diff but they look cool..!

Also another question are you using a 2mm washer under steering link ballstud .. you mention it in notes but not listed on sheet?

I just wanna get home and play with my car ... Work suks !!

Scott,

I just ordered 1pcs of the Excel part, just to see what it was.
It included 4pcs of the graphite spacers, two for front and two for rear. I think Hara was using the same parts at the ROAR Nats.

The 2mm washer under the steering link ball stud is located out by the hub, this will do the oposite of lowering the graphite steering plate. Again this will make the car more predictable and easier to drive!

Tip: Make sure your diff outdrives are in good shape, when they are worn you will loose steering and rear traction!!
The Delrin diff will make a big difference + it last allot longer!!

Good luck at the KO Race, I had plans to go there, but I have other commitments that weekend.....

Cheers
