If you keep the same size pinion gear, a larger spur will give you more acceleration.

So this mean I can get more punch? Which I really needed on my local track.

From order of necessicity:

1. P-Dub hard front bumper.

2. Place the steering turnbuckles below the bell crank plate and on the bottom side of the the carrier.

3. Use the Yokomo sway bar open ball cups for the bulkhead side of the camber links. Also, use HPI titanium ball studs on the bulkheads. That way you can just use a hex driver to take off the studs and remove diffs or change roll centers.

4. Use a button head screw for the outer servo mount (where the chassis makes a fin). That will allow the screw to grinde on the asphalt and not the chassis which will eventually snap off. ONLY do this mod if you run on asphalt that is bumpy or low traction.

5. Do a search on this thread for info on how to properly build a diff.

6. If you decide to run a spool, upgrade to either TiR worlds edition CVDs or Rayspeed axles and TC4 bones (which require much grinding, but are very durable)

7. Run 64 pitch gears

8. Get a servo horn with a built in servo saver.

9. Use RPM or Schumacher ball cups for the outer sides of camber links and all steering linkages.

10. Enjoy the best engineered belt driven car on the market. Then laugh at your fellow racers when they struggle to remove diffs or change spurs. (Disclaimer: This may cause bodily harm if fellow racers are 300lb bikers named Bubba)

Yes, but a smaller pinion will give you the same effect.

Yes! But with a larger spur I can have more option with gear ratio don't you think?

Jochim_18,
For RYPER raceway, I think you should run a rollout of around 26mm for a Monster. For the Nats, I tried monsters, Epic ROAR stock, P2K2 pro and settled on a Green Machine 3 for RYPER. The reason for the choice, it just felt better in testing than the others through the first sweeper on the straight. I got all motors to run the same qualifying times durring Fridays practice, the main thing was tunning the chassis to work on the track and keeping the lines tight.
You are welcome to PM me if you have any other questions or need any help.

Peter

PHEW did a bird crap on those solder joints
I think he needs a bit more heat in his soldering iron.

Yeah the steel spool is really hard on the universals or dog bones. Having much better luck with the Yoke plastic spool. Also we are using the Ti Racing Worlds CVDs, they are great.

My friend gave up using a spool after losing 2nd place in national series. He switched to use one way again ( Slow In - Fast Out style ).

I SHATTERED a plastic spool today. It came out of my car in 6 pieces. I think I probably messed it up practicing w/ mod before the races, b/c when I raced it in the stock class, it broke after tapping a pipe. Anyone else experienced this w/ the plastic spool?

Chadcapece...A friend put one in a cyclone (with delrin ouydrives) and actually smashed it including the outdrives.This is why I have stayed with a front diff in my BD...maybe not as much turn in ......but no breakages!!!!!
The only car I have that has no problems with a spool is my 05 xray

Come on Yokomo get your act together!!!!!
