i have had some fast c2 motors but the kamodo seems to be better all around.it is more of an rpm motor than the c2.i had to gear it 1 - 2 teeth lower than a c2

What is a good starting ratio/rollout for a C2?

The magic rollout for the C2 is 2.05". Thats what pretty much everyone in the A-Main at the 2004 On Road Nats ran.

I am new to 12th scale and I have a question... I had a set of Jaco rear tires on my car. I bought a differnt brand of rear tires and I noticed that on the Jaco rim the mounting flange is flush with the edge of the tire and the new set has the mounting flange set inside the tire .120. This will narrow the rear track width of the car by almost a 1/4 inch. How will this affect the handling of the car? Do you use track width as a major tuning option?

Sounds like you bought TRCs.

You just need to add axle spacers (washers) to each side to bring the width equally out to the ROAR max of 172mm.

Hopefully, your chassis has a center mark on it; so, you can measure the width of each side.

Thanks Mason.

Hadn't seen or heard that about the Komodo.

ran the used 12l4 I picked up today at my track after the race was over and was in awe of how much I enjoyed the way it drove. 12th scale has got to be underrated, I really cant wait to drive it again ...

Welcome to the fraternity!

crap!!! I hate reading post's like this !!!! I have a just built CRC car and no place to run it

Parmas need to be spaced as well, at least they used to.

Can anyone enlighten me as to what model RC12L this is??
I'm looking at buying it, but the seller doesn't know what it is.
Cheers...

Track width is a major tuning aid in link cars so it should be in a t-plate car as well, but I really dont see it much. We (Rice, Chicky, etc.) always set the t-bar cars to max roar width and be done with it. Any L4, RugRat or T-fource cars Ive built for others that were fast were always roar width. The Rev3 I used to run were sometimes very narrow in the back with certain set-ups from a fast friend and I tried narrowing up the CRC 3.2r I now have. Sorry-cannot say Ive ever done it with the L4 or T-fource.

I would blab on and say that if you make a narrow car work really well, but the car sucks @$$ at another track or layout-that would be the first thing I would change. Sometimes with 12th scale-just like TC's, something crazy will work one time, but usually not be a part of your standard set-up.

Track definately affects handling dramatically. Before you even start playing with track width, its really important that your wheel spacing is even from the centerline of the car. Uneven wheel spacing can make your car feel as though it is tweaked. Also, when adjusting track width, check your endpoints afterward. The turning radiuses can change unevenly if the spacing of the rear tires changes relative to one another.

A wider track width will transfer less weight laterally at the back of the car. Widening up the car can free it up. Conversley, a narrower track width will transfer more weight laterally and make the car be pushier. Basically, the farther away from the chassis centerline the tire is, the less leverage the chassis has on the outside tire when it is cornering, thus pushing down on it less.

You can also add shims to the front of the car as a tuning option. A wider track at the front will make the car be more stable and pushy, a narrower track will make the car more agressive and steer more.

Thanks... thats what I was looking for

eforer - Nice website! Did you do the album cover for Diana Krall and the Strokes?
