That argument could have applied when the TC3 first came out - nearly everything THEN was belt (few non-mainstream or non-performance exceptions)

there are more shaft-drives out now than there were then.

That rumor has been going around for a LONG time. . .

On your Factory Team TC4 what has been the best Spur/Pinion combo you have ran..

On stock motor, on carpet, I run Epic, KOS, Monster motors.

Thanks,

The manuel says start with a 72/27 combo for 48 pitch gears using an rpm based motor. I would start there and keep an eye on the motor temp during practice. If you cannot keep your finger on it at all then it is too hot use a smaller pinion. If it is warm try a larger pinion. If you are using 64 pitch just divide out the 72 by 27 and use the closest ratio you can get.

What type of tire do you run with (foam or rubber)? If foam, what size? What size track approx.? Is the track tight or open? On my track, the average lap time is about 7.15sec running 72 spur/20 pinion on new foam tires (62mm), tight layout, 60x30 track with an epic motor. Monster motor start with a 21 tooth for the same conditions.

Foam. Small track, oval carpet, we turn from 65-71 laps in 4 mins. Tight as hell. usually 4-6 cars. Track is 4-5' wide straights are 20' long then into the turns.

28mm Jaco foams is what I run. Avg lap time for me 3.1 on the money lap after lap, others run 3.2-3.9

Thanks again,

Oh ok, I didn't know that you were running on an oval track. the 72/20 gearing is good for the road course layout were am at. Our straights are about 50' long so you may want to try something in the 72/17-18 range with full size foams on such a small sized track. And gear up to maintain roll-out as the tires wear down.

Post some pics of these small tracks, I've gotta see what other small tracks look like. I run on a track in the basement of our local lhs, so the track has columns in the middle of it (I beam columns!). Usually geared around 100/32 for 64pitch. Here's a pic of the track:

Not only TC3's..

nice track!! I like how you took the beams out of the equation. . .unlike the poles at SoCalRC where it's not uncommon to hear chants of "POLE. . .POLE. . .POLE!"

This is our track in Billings, MT. We have to set up and take down every race day. This is 40' x 67' in the pic, but we can go as wide as 90'. We cut the carpet width to fit between the poles and we use vinyl down spout for dividers with our own creations on the corners. This is in the basement of our Shrine Auditorium.
We do our big 2-day races in the Holiday Trade center where we get out all the carpet and go 40' to 52' deep by 90' wide.

Thanks, my dad thought up that design. It's nice to not have to worry about hitting the poles, but it's still a pain to find a good spot on the drivers stand where you can see all the turns. Most of the time you'll have at least 1 blind turn


Awesome track, so clean! Love the nice wide lanes. On our track if you get off the line your in the wall
