Around The Table With Paul Lemieux(RC-America/Thunderpower)

awesome.
i agree 100% about getting it on the track. it's just that here, people want a set of rules to memorize. roll center isn't confusing if you look at a picture (the orion animated one was sweet). but when people start generalizing, it all craps out. i was trying to save you 5 more rounds of this!

A rhodes: I guess that it is possible that this motor dosen't allow it to be mooved very far back. I would mess with bigger spurs and pinions untill it is right. or if you get desprate you could bust out the dreamel, but it shouldnt be nessissary.

Paul,
Can you help me dial in my tumbleweed? I tried checking out this website
http://prairietumbleweedfarm.com/
But it really didn't help me all too much although the sections on tumbleweed testing and the GIANT tumbleweeds sure are great reading!

I race with xraysteve and a bunch of xrays, I have a HB Cyclone. It's no fun racing with xrays because they all seem to roll over all the time. There must be a good way to help these guys out so I can have a clear track without xrays on there roofs all over the track

Hey Paul, wondering what you thought of 'roll' in different classes. Couple of my friends and I are always argueing over the use of roll. I usually end up running roll, they do not. typically running stock/19t foam tc, stock 1/12 and some rubber carpet stock/13.5.
just looking for an opinion.

with rubber tires, our arms will angle down to the chasis a bit, and the above holds true. however, on foams our touring cars run almost flat arms at r/h. if the arms are completely horizontal, changing the camber link inclination will have no effect on the (static) roll center. see the following for reference:
and if the arms angle up to the chassis (old rdx setups and high rear roll centers in general) the effect of the camber link on roll center is reversed. it's all to do with the lower arms.
however, like paul said, the larger effect from the links is related to camber gain and what that does during roll. if you want to change the roll center, do it at the lower pins. it will be much more profound (and simple). up is up, and down is down. otherwise, there is no blanket statement about how changing the links will affect the r/c.
obey the man. i just thought i'd offer a visual on the deal to help him out.
i also have more visual material for you, specifically, paul. what?

Hi Paul,
What is your procedure with spec rubber tires? do you rotate them?
Im having trouble at some tracks. The front right tire is taking a hard beating, making my car push. I tried rotating tires but that made the car feel twitchy... Any solutions?
Thanks for any help
