about the FDR your right 2.166 for the TC and 2.4375 for the moor speed
But are the 18 tooth pulley made for torque motor like brushless?
and from what i understood there is two 18 tooth pulley ( front , rear ) on the TC
thank you

The Two 18T pulleys are the center pulleys to the right and left of the Spur gear.

The 18T pulleys give the car a 2.16 IR, which makes it easier to gear 10.5, 13.5, and 17.5 motors.

Yeah it will be easier to gear with the 16t pulleys

So long as you can hit your final drive ratio it doesn't really matter which pulley you run. The 18T just helps get the lower FDR needed for 17.5 and 13.5 motors. The 18T pulley on paper should also be a little more efficient due to less belt wrap. With the killer lipo's and brushless motors that we have we won't really be able to tell the difference.

I would think with the 18T pulleys there would be more belt surface area touching, meaning more belt wrap...right? I plan on running the VT/A class and trying to figure out if the 18s would help or hinder me?

The way Paul L. explained it to me was that the bigger pulley didn't have the belt pulled around a smaller area creating a tighter curve in th belt. That's why when we go from the 16 to the 18 bigger belts are needed. If we tried to use the same belt it would be super tight. I might not be explaining it the correct way so hopefully someone with a little better knowledge in this field can come along and help us all out.

Default Rug Rubber??

OK guys. WCE chassis on a tight, low traction carpet track - rubber tire, 13.5and 10.5 lipo. My question is; spool, 1 way or diff in front??

Forget the one way. Spool would probably be best, but depending on your set up and driving style, a diff might yield similar lap times. Give both a try and see. In any case, loose the one way.

Not sure if this has ever been discussed but I am going through my cyclone fixing some things and such. I had to replace a cv axle because I bent it (is there a fix for this?) and having a over abundance of spare pro4 axles decided to try them. The fit with the exception of the right rear which needed to be shaved down to provided clearance for the diff nut. Being longer I would imagine they might not hurt the outdrives as bad since they can't spread them as easy. With two races running 13.5 I have yet to see wear on the rear...I haven't tried the pro4 axles in the front yet though.

Spool in front will be helpful getting out of those tight turns. If you run a diff and your competition runs a spool you will get eaten alive coming out of turns. Especially with todays brushless torque machines. If traction is too low the aggressive nature of a spool may be too much. In that case, the diff might be the better choice. Just make sure your diff is TIGHT.

Most of the time it's a spool for the win!!!

just like shaun said, spool for high bite track, and if your track uses wood barriers, forget the spool, if you tap them once the car will explode.

I run 1.35 rubber tire, WCE chassis on low traction carpet with a one-way. Everyone runs a one-way.
