What is the ideal spur gear size for stock brushed to start with?

Spur size is your choice, But the on Going idea is that the LARGER the SPUR the more TORQUE it has over a smaller spur. So , with stock motors not being as strong as Mods. the lager spur would get you off the corner faster.

And to get the "REAL" good FDR you need to buy the New Brushless Bulk head for more movement of gear mesh.

Put a 106 spur and if you can get a 32 pinion to adjust, that would give you a perfect roll-out for a stock 27 turn motor. If there isn't enough adjustment, use a 34 pinion.

I thought that the larger the spur gear, the more topend you got. I thought that if you went to a smaller spur gear that that creates more torque.

Kinda like the same idea when you start cutting your motor. the smaller the comm the more torque you get. i could be wrong though.

I think you got it backwards. Larger spur means the pinion has to go around more times for the spur to go around once. So less rpm from the motor gets to the ground. Small spur will have higher top speed but motor has to work harder to get there because it has less leverage I guess you could say.

Drill a 3mm hole in the Ball cup and unscrew the whole ball stud, instead of unsnapping it every time

Yeah thats the best thing to do, otherwise i use long nosed pliers to grip the ball cup on the arm and twist it off.

fjm9898, i think there were comments about it a couple of weeks back.

Personally i wouldnt bother playing with the mounting positions just stick to your normal settings. Its probably not gunna make that much of a difference unless you are a top driver, otherwise everyone would be using the different mounting positions.

Grr, I bought a 31T pinion. Too small! Won't reach the Spur 100T.

Does that mean that the Cyclone is not suited to running motors below 11T? I have an 11x2T Team Checkpoint. What pinion should I run with the stock 100T spur? Anyone run Checkpoint with the Cyclone?

Thanks!

Buy a bigger spur, 108 is meant to be the max for 64 pitch. Although you can squeeze in a bigger spur if you lightly file down parts and dont mind it sticking out slightly under the chassis.

Which car do you have?
If you have the original, a little filing on the CF plate will help it clear the spur. On the alloy middle braces, I think it's fine.

A 110 will fit and sit either flush or just out of the chassis. I run a 3.5R with a 110/25 combo with no issues. Given that I get to the track like once a month if I'm lucky and that our track is outdoors and surrounded by trees.. it would be easy to surmise that spur gets ripped to shreds.
(My car runs on crash-o-hol)

However - it's running great! It getting more chewed up from the pinion wearing than anything else..
