That's Funny you mentioned the belt flipping. I built my car just like it said out of the box and the belt flipped immediately the first battery pack I ran.

seems like a lot of people use different methods of measuring and checking, but this would be a constant method, no matter what size tire, rubber/foam, etc....
probably should have typed that a little faster.....

Why are downstops listed on the setup sheet instead of uptravel, if at all? It seems like kind of an arbitrary thing if I'm understanding this correctly. And, is 2mm over ride height what most people do for foam/carpet?

actually, the front belt that flipped on me in Vegas back in September was the original one from the March 05 buildup... and run it every weekend! id did last a good long time.
it really didnt wear out, but i think like Woody said above, something hit it and made it flip once, then it just kept on doing it, till i swapped a new one on... no probs since then.

yeah you are right once it flips once, it seems much more prone to flipping. After changing two belts in a single day at our last big two day race. I have had enough. Changing a belt isn't really a quick thing to do either.
Thats why I was looking at solutions, its seems to happen too often and frustrating if I have to change a belt every race day. Of course days I stay off the pipe then I don't have near as much trouble. and then there is the days... well... people get in my way
yeah thats it.

Syndr0me, between 1 and 2 mm over ride height is what most people use for foam. People that race rubber tires a lot get in the habit of using arm downstops...but what really is important is how much uptravel the car has...for both rubber and foam. I usually run 2 mm uptravel all around.

Okay, so does this process sound reasonable?
Back off droop screws enough that I can adjust ride height easily, and do so using spring preload only. Then, raise the chassis to ride height + uptravel (so if your ride height was 5mm, and you wanted 2mm of uptravel, you'd put your car on two ride height gauges at 7mm) and adjust the droop screws until the wheels just touch the setup board.
Is that a pretty standard, sane way of doing all that?

the great thing about this other way i use is that anyone can duplicate it. plus works no matter what tire or chassis plate you use...

Belt
From what you guys are saying about the belts. Should I change my brand new belt?

I've never had my belt flip over. I run with layshaft 3/4 up and no tensioner. Everytime it flips, do your batteries always hit it? Are you sure the your differentials are put in you bulkhead correctly (They're off set and the front one has to have the long side to the passenger side, and the rear have the long side to the driver side.)

It has me stumped too. Mabye I just have a bad belt. The belt was really twisted in the package from the factory, looked like someone was trying to make a paper bird out of it. LOL That could have something to do with it I am assuming.

buggy richard, are you sure you built your car right? I havnt had any problems with the belt yet... I have never even heard of this...
I guess i would rather my belt flip than have to replace arms everytime i go on the track though....
