Torque steer is basically the result of what's called "Conservation of angular momentum". Letís pretend that you are looking from the back of the car. The shaft of the motor is inline with the car. Now, imagine that motor is accelerating, turning counterclockwise. At this instant, the constant value (inertia) stays the same, but since the motor is speeding up, the angular momentum of the system is getting higher (the direction of the moment is point to the back of the car). Due to the physics law of conservation of angular momentum, in order to keep the angular momentum conservative, the entire system will react to the changing in the momentum by rotate the entire car clockwise (the moment is point to the front of the car) to keep the angular momentum conservative. The moment or torque will exert force on the right side of the chassis downward.

A good example would be if you take your car off the ground, and look from the right side of the car. Now pull the trigger, your wheels will be spinning clockwise (the moment is point to the left of the car), but the entire car will be turning counterclockwise to react to the moment. The reason that your car is not trying to spin as fast as the wheels is because the car has much larger inertia, so it takes less angular velocity to achieve the same angular momentum.

So, on a shaft driven car, if you take the car off the ground, and pull the trigger, not only the front of the car will lift up, but itíll also try to lean on one side (depends the direction of the motor that is turning). It may be hard to feel just by holding the car, but the force is enough to cause your car pull on one side on the track.

i think people can talk all they want about g-force this a torque steer that

but what it comes down to is that MOST (not all) of the top drivers out there are driving belts

and it is that simple . . .

Is there a website where I can who is winning all the big races? All I do now is see them in the mags here and there. I know Xray seems to be winning lately, but weren't PRO4's winning a bunch early in the year?

hummm, pic's you say this is the only one I could find. Tommy is out of the UK so he's hard to get a hold of.
This car just took 3d at the summer sizzler a trackside, the only yokomo in the feild. and the only shaft car in the main.

Sobottka also runs a shaft car he took second

Wise....you forget the SRD shaft tourer took second....haha. You can try to catch me at Vegas or Cleveland buddy!
Wise and I are both running shaft tourers that are as smooth as belt cars. We have our own custom ride which we are producing, the SRD. Wise is running the Yok as previously stated.
Last year I have proven that shafts are not behind belts in performance or for efficiency. I made A's in stock and 19t at Vegas and Cleveland. These were two totally different beats as far as traction and layouts and the shaft car had no problem keeping up with belts. Wise will agree with me that shafts are still fast...if not faster. The hindering performance of the TC4 and breaking of gears in the Evo 4 has turned many people back to belts. With so many wins from Corally and Xray...and not seeing a win from Associated, how could people not be running belts? What wins on Sunday...sells on Monday. TC3's are still fast...I could prove it.
