Battery forward.

That run was with a stock brushless (the new SS4300) so torque at the wheels could have contributed to the problems -- the SS4300 has the same torque as the SS5800 -- but it was still loose, even on-power.

Hello Futureal,

I race on a low bite carpet track all the time and I have found a really good starting set up for tracks like that!

Front End:

Droop: 3mm
Toe: 0deg
Ride Height: 4.5mm
Pivot Support: 2R (Yes, 2R, dremmel down the CVD's)
Camber: 1deg
Caster: 2deg
Roll Center: G+ Low
Shock Position: #3
Shock Piston: 55
Shock Oil: 50wt, Losi
Shock Spring: Purple
Camber Link: #2
Ackerman: Forward and Flipped
Arm Postion: Midle
Spindle Ballstud Washer: 2mm
Front Drive: One Way


Rear End:

Droop: 5.5mm
Toe Inn: 3deg each side
Ride Height: 5mm
Camber: 1deg
Arm Spacing: All the way Back
Camber Link: #6B w/Low Ballstud
Shock Position: #3 Outside
Shock Piston: 55
Shock Oil: 50wt, Losi
Shock Spring: Purple
Pivot Support: 0R, Bottom holes
Roll Center: Low
Standard rear end!

Batteries: Forward
Any aditional weight is placed as much forward as possible!
I have 30gr in my front bumper
Body: Protoform Stratus 1
Tires: Sorex 28R
Insert: Orion/JB Blue (Light Weight, Carpet type) Important!!

For more rear traction/less steering: Rear Camberlink in #1A w/tall ball stud.
For more steering: Ackerman Position in std position and Arm full back.

This setup is extremely easy to drive and very precise!

Could you please try it and get back to me with what you think?
I am sure you will like it!!

Cheers,
Eirik Andreassen

Try 2A on the rear camber link, more rear droop and sorex 28's. on your present set-up.

futureal- that would be 2 degree per side with the zero degree hubs on. I also feel that the sorex tire's offered me a little more grip than the take off tire's with this set up.

I gave up on my car with a brushless and went back to stock. The problem I had was that I could turn really fast laps, but the car was very inconsistent. The rear end had waaaaaaay too much articulation to it under power. It became a point and shoot kind of thing, you couldn't flow the car. Another thing I did was add a ton of drag brake to the radio, that made a huge difference. I was able to get the car to push really badly on one experiment...I moved the rear shock all the way in on the shock tower, and then it really pushed. I didn't spend a whole lot of time with this setup, but I think if I would have gone down from the purple front springs I could have maybe gotten rid of the push. The things that really helped the car though:
Going to the 1/2 degree rear hubs
going to -100% on the throttle Expo
Putting some drag brake into the car
Moving the rear shocks in on the tower

Now they are running in the unlimited mode, where before we had the limiters on. I think that effected the handling too. As you hit the limiter, there's a sudden weight transfer forward. So that could make a difference too.

Default Aluminum Screws

Has anyone had bad luck with those colored anodized aluminum screws. In the process of replacing my steel screws with blue aluminum screws, I have had 2 out of 30 shear off. I was not over tightning either.
Do I just have bad luck or get a bad lot?
Have any of you had simular bad luck with aluminum screws?

When the XXXS first came out I had the same problem. "Bud's" makes a front bumper that is as wide as the body and protects the front end of the car really well. I drilled holes to take the weight out of it and they are fairly cheep. Just my .02

imjonah: I would avoid aluminum screws for racing, since you tend to take things apart repeatedly and sooner or later they will weaken and strip. Steel or titanium screws have served me best, and still get a bit of that "cool" factor.

HRP distributes MPH Products items, so anyone who deals with them can get his stuff. I know S&N's Trackside hobbies (www.trackside.com) has it, but I don't know if he sells it through the web or not. I'll ask tomorrow when I go racing

... if you're looking for some "cool" factor, try out the stainless steel screws... or better yet, titanium.

aluminum screws will just keep on stripping...

futureal: 1/2 degree rear hubs should help a lot. i actually even use 1 deg rear hubs in low bite tracks and really helps keep the rear end planted. a longer rear camber link (ie. 1A position) should also help. these are some things you may wanna consider trying out. let us know what works out for you.
