I found out that Type A tires work pretty good in a Carpet Track...

What I like about rubber tires is that they do not wear like Foams, and the tire diameter do not change that much over the tires life. Overall the Foams do tend to work better though..

Our local track does not allow the foams, so it is a mute point for me.

Still waiting on my Cross....

I have also heard good things about the A-type tire. My track may consider running a spec tire in order to keep it even, and the A tire is the front-runner.

BTW, I put both Kyosho Indy cars on ebay...opening bid $75 (a steal if ya ask me).

Lata on...

We use the B tires at our track. We allow any tires except Capped Foams in our race series.

I don't race on carpet, but consider this. You'll get a lot more traction on carpet than on asphalt. So, it is likely that you will need to make changes to reduce traction to avoid traction rolls and oversteer. The things that you can change to reduce traction are 1) use harder tires 2) use stiffer springs 3) if you use stiffer springs, you will likely need more dampening. Dunno if that helps you much, but hopefully it points you in the right direction. As far as gearing goes, I would start in the mid 5:1 (like 5.45:1) gear ratios and reduce your pinion one tooth at a time until you get the balance of acceleration and top end you are looking for. If the track is pretty tight, you'll probably want to run somewhere around 6.00:1. Good luck!

I paid $175 for a brand new F103TRF a few months ago. Tamiya had a closeout special on them a while back. Obviously, it depends on what it comes with, but new, it came with a set of Type-A rubber tires, a black can Tamiya tuned 540 motor and no body. It has every hop-up already installed, so there really isn't much you could add to it. Figure that a Tamiya GTP body will run you ~$40 and the tires are ~$15 per front and ~$17 per rear set and a set of wheels cost ~$14. I hope that helps. It's good to see more people getting interested in these cool cars!

Carpet racers... try the Ribbed tires, type A from Ride along with the special foam inserts. They work great on carpet.

psycho: thanks for the answer about converting to regular gears. I'll do that as soon as I get the car. I used to run an old Kyosho F1 back in the day, and it used standard 48pitch gears so things were simple with it.

oh ya, one more thing psycho.

isn't 5 something ratio is a bit high?
but this will help me with acceleration right?
so is like i will get the 100T and like 18, 19, or 20 Pinion so try it out?

It seems high, but you get the best performance out of a stock motor when you use higher gear ratios. I use either P2K Pro or Reedy MVP motors in my cars and they are much faster running in the 5.45:1 to 6.00:1 range than they are with 4.xx:1 range. I suppose, if you were going in a straight line, eventually, the lower ratio would make the car faster, but you generally need more acceleration than top speed on a road course. Your 18/100 combo is 5.56:1. Actually, you should download Easy-RC software. There are some useful tools on it like the gear ratio tool. www.easy-rc.com

Oh, ok thanx...

I race with a couple guys that are running the black can motor and it seems as though the same principles apply to the 540 as they do to stock motor like the P2K. They're not quite as fast, but they aren't slow either. You're going to have to use Tamiya gears in TCS, so don't change to 64 pitch. I would run as high a gear ratio as you can make with Tamiya gears, but have bigger pinions on hand in case you need more top end. Running a higher gear ratio also helps you in the runtime dept. too.
