Could you not just use the higher internal gear ratio of 1.9 (38 Spool / 20t) for your calculations?
i tried, belts don't fit.

A quick google search found several online stores that stock it. If your local track/hobby store can't get it, ampdraw.com has it in stock.

Good to know.

When you do find the front spool, please post where you got it.. I'll do the same.

I'm wondering if someone could give me a 48p gearing starting point for an LRP 3.5 motor running rubber tyres on a tight asphalt track.

I've looked at a few Team Drivers setups and they seem to run 116 - 118 spur with 20 - 23 pinion for a 3.5 BL. Is that 48p or 64p? I'd definatly need 48p for our track.

That would be for a 64p. For a 3.5 BL 48p you would want an 84t spur with about 15-16t pinion to get about the same PDR.

EA
Is the trinity IP3800 flat on the bottom or does it have the humps?

Default Question about FDR on a T2'008 Rubber vs Foam

How can I match a FDR of 4.5 on the Foam car to the Rubber car knowing that only certain combinations of spur/pinions will work on the car?

I'm running 17.5 brushless and trying to get to a 4.5 that was at when i ran the foam car as a rubber car. now that i have the new drivetrain (2.375 ratio), how can i get back there?

The gear chart from xray have the two cars at completely far apart FDR's for the same gears. it's very confusing.

I've got what I think is a weird problem.

It seems as though the inside of my pinion (Part on the pinion where the lock nut is tightened down rubs against my drive belt.

Obviously this causes excessive wear on the belt. So I can only get a few races out of them. I've tried re-positioning the motor, but no luck. In order for the right mesh, it has to be where it is.

I'm running a brushed motor with the 2.375 (20 inside pully).

Any ideas?

The quick answer is you can't. Most, if not all of the people who run 17.5 brushless use the 1.7 ratio pulleys.

I ground down the pinion setscrew a little so that when it is tightened, none of the setscrew is above the diameter of the body of the pinion. They still hold fine (since the threads above the pinion body aren't contributing anything anyway).
