Ballpy.....we talked about this a few pages back. There is no performance gain with this....you use this setup if you are in the forward ackerman holes in the chassis. When your bell cranks are forward and you have the stock servo location with the stock servo saver it will put the tie rod on a funny angle and can lead to uneven throw. So you can do this mod or space the ball stud on the servo saver out further so it stays inline. All its doing is keeping everything lined up properly.

Default chassis drag

I recently noticed that the rear corners on the underside of my chassis are getting a build up of tire goo/rubber from the carpet, as if they're dragging a lot... is it "normal" for the chassis to rub the carpet/ground? Or have I got it set too soft?
I've got the low roll centers in back, and mid in the front, siver springs in back, long camber links in back, sway bar front only... about 5mm ride height... any suuggestions?

thanks,
Brian

Brian....are you talking about the edges of the chassis right in front of the rear arms like by the motor and the last cell slot? If you are talking about the part infront of the rear arms you can take some sand paper and round the edges more so you get more clearance. If its the back edge of the chassis behind the rear arms by the bumper then raise your ride height. Or try a rear sway bar or just go up one spring. If your chassis is rubbing its going to slow you down not to mention maybe rip the carpet. If the goo is only on say the outside edge like the side that would rub in the sweeper(motor side) add a litle more pre-load to that side like a 1/4 turn on the shock.

Kevin--
Yeah, the chassis by the motor and last cell slot... but it's not just the edges, it's that whole flat area there, within an inch of the edges. It seems pretty equal on both sides. I hate to make the back end any stiffer, because I've been struggling for rear traction until recently... but I'll have to give it a try, thanks...

Brian...are you racing at trackside? What tires are you running? The Todd hodge setup from the novak race last year is a good setup might want to try it out. Next time Im up there find or come see me or Brian Jucha and we will help you get your car working better. All that rubbing is not helping and you should not be lacking rear traction. When I was running rubber tires for the novak race I was at almost 6mm in the back and 5.5mm in the front. You could just raise the car a little....but a thin rear sway bar will keep the roll down and will add a little traction to the back.

Kevin, I'm at Trackside most Tuesday nights... I'm using the Take Off 27 tires. I've got the car working as well as I ever have, but it looks like I could be doing better if it wasn't rubbing. I'll try raising it a little more first, then try the sway bars...

Kevin K,

I need some help. Building a Graphite + for mod racing this season. Was wondering if you might be able to send me the dialed set up you and Jucha are running????????? Will give me a starting point. Thanks bro.

You coming to the Halloween Classic in November? Ray Huang's track in Cleveland. I "thought" I saw your name on there.

Rob...you got mail. Yes Im going to the Classic but I thought it was in October....not November Im running the MF set up off the losi site and the car is working very well....but that setup calls for Blue congo's....good thing I have some left over from the SW days Losi blacks feel close to the same as the congo blue if you dont have any congos. Anyway I asked Brian to Email you the setup hes running....both our cars are working very well. My car rolls more then his car but we will see what we do after this weekend.

Almost done with the build of my XXX-S G+ after having to put it aside for a little while until I could get some new thrust balls (the kit came with a set a 7 thrust balls and 1 diff ball in a bag supposed to contain 8 thrust balls) to solve a kit problem.

Question: I noticed the front arms wanted to bind when the screws on the rolls centers and front brace were tightened flush. If I keep the screws loose the free movement of the arms returns but there is a *very slight* bit of play in the roll center graphite piece. The screws are still flush with the chassis although not all the way "in" and I feel it seems pretty solid but I was suprised. Any ideas here... anyone else have this problem?

Thanks...

Definitely tighten the screws. Those roll center blocks must be snug (do not over tighten). Often times the graphite parts do not fit as wanted. Try filing a tiny amount off of the arm where it touches the roll center mount. Sand a little at a time until free. This should solve your problem.

I noticed after a slight filing and then polishing the hinge pins the arms are very free.
