At club level racing it's driver and not the car.

Once you are good then the car comes into play. And well the pros run what they can win with. So what pro's run a shaft drive?

Default not to beat a dead horse

It isnt a factor of what the Pros run, but what the factories dictate, what they pump the most money into AND what performs. Just two short years ago, Atsushi Hara was smashing people with the Pro 4...that would be 2005. Then, some genius over at HPI figured he would really push the Cyclone to the limit. Following Xray, Tamiya, Yokomo and Corally, folks got away from shaft because of torque steer. Yes, belts give you more tuning options and better diff access in most cases. But as far as acceleration, shaft is better.

Will torque steer be noticeable in 27T or 19T?

Depends on how you drive as to how bad it is... If your smooth on the throttle then its no problem. But if you have a '540 trigger finger' then it will steer strange.

Smooth is fast anyways and better on motor and batteries!

With correct setup you can eliminate torque steer, I run a 4.5 with a TC4 and I have no torque steer.

Yes I run foam on carpet, but without traction compound, not allowed at the tracks I race at.
Also rubber asphalt and brushed concrete

There's no way to eliminate torque steer, it's physics. If you race offroad, you know that the torque of the spinning wheels causes the car in the air to either nose up with throttle input, or down with brakes. The centrifigal force is exagerate with the tires and wheels, but you get the idea. With belt cars in onroad, you have that affect front to rear, with a shaft, it's side to side. Get on the gas, and the car pulls right. No tuning will get rid of that. You can try and compenstae for it, but there will always be a side affect which is unwanted. Someone said Hara was fast in 2005 with his shaft car, yes he was, but he is faster with his Cyclone.

well to go along with his new cyclone he has new 1.24+ packs.....i have noticed that moving from my ib3800s 1.21 to my wc 1.24 i had a huge gain in speed, i just need to get control of it in my irs tc3....

It depends on the track but around 16 pinion, 78 spur for the smaller ones, upto around 21 or 22 pinion on larger ones

Races aren't won on the straight, but in the infield. Sure there may be some gain on the straight, but the motors those guys are running will give you more than enough power anywhere else on the track. It's about how your car can carry speed in the corners and his cyclone is faster in the corners. BTW, Hara helped develop the Cyclone and Pro 4. If shafts were better, why did AE, HPI, Yokomo (they still have a shaft but their top car is belt), Tamiya (they have the EVO but it is being fazed out of their TRF line), go to belts? When's the last time a shaft car won against a belt car?
