As far as running a 21.5 indoors at my local carpet track, I have found that I actually run better by not gearing the car to be as fast as the rules allow. The issue becomes usable speed at the track I race at. While I could go faster in a straight line, I haven't been able to find a setup that still turns on our tight layouts. Either I would have to slam the brakes every corner, coast 1/2 down the straight, or dramatically improve my setup skills. I've been using a 4.6-5.0 FDR for lipo/21.5 in my TC3 and have been happy with the performance overall. Again this is on a fairly small track with very tight corners.
I am curious on the HPI Pro-2 how you got rid of some of the slop in the front end of that car. On that car, I'm using plastic a-arm and caster blocks. I have graphite parts that I haven't gotten around to yet. The only pain with the HPI Pro-2 is having to run split-packs with 4-cell, unless you found a way around that.

from the VTA Rules page:
Novak motor is the ONLY motor allowed at this time, because there are no ROAR mandates or restrictions for the 21.5 brushless motors. All house track rules regarding LiPo usage apply. Final drive ratio is to not exceed 4.2. Motor timing advance is allowed. 12.5 mm rotor diameter maximum (no "tuning" rotors are allowed).

Robk, just start with a good AE team posted rubber tire setup for 17.5/13.5, and tweak it from there. I'm also running VTA at the Classic, with my Cyclone. I prefer the one way in the front. Picked up .1-.2 sec on my best lap over a front diff, during my testing this past weekend.

I believe this word has lead to the confusion. more accurate would be "final drive ratio is to not be lower then 4.2. "

If any clarification were to be done the word "numerically" could be used, e.g. "Final drive ratio is not to be numerically lower than 4.2."
I think you should have referenced definition 2 before replying. (j/k just couldn't pass that one up!)

Anything from 1:1 to 4.19 FDR is illegal. How's that?

I know this kind of seems like a stupid discussion, but I have seen a lot of confusion among newer racers over it, and newer racers are a big part of the USVTA target audience. Rolleyes or not, spelling it out blatantly like that would eliminate the confusion and we could go back to arguing about important stuff like other 21.5 motors and rear spoilers (not to mention neon fades nash ).

I would start with the box stock setup for rubber tire and go from there, you might have to use softer springs. I have my car setup with a 4-cell 17.5 and its pretty close to weight so I dont think you would have to add much. I personally use a oneway or a diff. At my track the spools seems to reduce steering.
If you get the chance set your car up at your track and then you should be able to fine tune it when you get to the gate. Thats prettymuch what I ended up doing. I'm looking foward to running VTA (real rules) for the first time.
If your curious I"m running a Pro-2.

I've been running asphalt ewith my VTA, but I use a spool in both my Cyclone and TC5, and the Cyclone even has the center one way. I plan on keeping it the same for when the carpet comes in. My TC5 is unproven on lap times, but I do think it's faster than my Cyclone. I'll find out this weekend.

What are you confused about? Everything you said seems spot on. I can't find anything you typed that leads to us seeing any confusion on your part.
When you see it phased "Final drive ratio is to not exceed 4.2."
...guys (at least some) don't know what direction that means.

FDR not to exceed 4.2
LIPO temo not to exceed 110 degrees....
words can mean many things.....

Some of our TA gurus take out any toe-in on the rear, Make it 0 degrees.
Yo Kregger, how things? Are you guys running VTA a lot at 360? Just curious cause the holidays are coming and theres always a chance I may be in NY for a few days. If I do come up maybe I'll bring my VTA car.

I can see running the spool outdoors, but On a track like 360 the spool just doesn't pay.
