Default Torque Steer

Just wondering, does the NTC3 and the Fw-05R suffer from torque steer very much? Being shaft drive.

my FW-05R doesnt suffer torque steer althought thats on the track but i will have to test it holdigg the car in the air and accelerating it. but from today i remembered accelerating all the junk out of my exhaust out of my FW-05S and notice my steering sort of shaked abit! like 1mm to each side! but didnt pay attention to see if the car actually swinged to one side, this was also done in the air.

I don't know about everyone else, but my NTC3 never had torque steer. It always tracked straight.

do you even know what Torque steer is?


It not when the wheels turn.......... Its when the Torque of your engine steers the car. Because of the Way the engine is mounted in the Shaft Cars

what did i mean by that?
of course i know what torque steer is

A lot of people before had a lot of torque steer issues on the NTC3, mainly because they didn't know how to set up the diffs properly or the way they drive and have the car setup. Its possible limit it to a small amount. I've heard the Fw05R has less torque steer. Both are great cars though the Kyosho, being the better, if not the best shaft driven nitro tourer.

LD3 is the best Shaft car... ive seen.


The hole RB team. runs them here in Aust.

Torque steer it's a pile of old wives tale.

My new shaft drive car has none from the moment it hit the track.

It's a myth.

mt ntc3 suffered from it. when coming out of slow turns to a straight away. it always went the same way. but like was already said, you can limit it by setup. loosen the rear diff a little bit.

It is a myth. Doesn't exist.

You can have the same problem of a belt drive car if you don't set them up correctly.

No.

Due to the longitudinal mounting of the engine in shaft driven cars, there is a torque reaction of equal value and of opposite direction to the rotation of the crankshaft.

The more torque the engine produces, the greater the torque reaction.
This torque reaction causes a lateral weight transfer.

The engine facing either forward or backwards will determine to which side the weight is transferred.

Typical belt cars experience the same torque reaction but it is manifested in a front/rear weight transfer since the engine is mounted laterally.

This is basic physics.

It is a lot more complexe than that. There are other forces like to centre drive shafts which are in equal but opposite direction that cancel out the force and the torque.

It is not like a rear wheel drive car in which the engine and shaft are inline and are rotating in the same direction. This creates a force and due to the distance a torque in which you can see the car tilt to one side on the line.

Shaft drive cars are espically designed to have as close to zero as possible torque. There will always be some uneven torque because nothing is perfect. This doesn't mean that the torque will be noticable. I have driven a few shaft drive cars and never experienced this. They include FW05-S, FW05-R, NTC3 1/8 buggies and my mugen MSX-3. Due to the uneven surface it is very difficult to tell weather the buggies experienced a torque steer or not.

The first run with my new car it was turning under accelration and braking.

I thought possibly this torque effect. I then put the car on a setup station made sure that the geometry was correct. Shocks of all equal lenght ride height, droop all exactly the same and I didn't have even a hint of torque steer under power or under brakes. The car would track dead straight under either condition.

ask SPracer and RJL I'm sure that they have not experienced any torque effects

There have been many threads about this and it all comes down to people opinion.

I can only tell you that experienced racers that have used both belt and shaft drive cars that can set up a car perfectly don't think it exsits. I haven't experienced it and I'm sure that if you set up your car perfectly you wouldn't notice it either.

No, it's quite simple. Those other shafts are driven by the engine. They don't magically generate an equal and opposite force to cancel out the engine torque.

I think you just described the engine's torque reaction, here.

Quote:

There is no passive chassis design parameter that could eliminate the torque reaction from a longitudinally mounted engine, and the lateral weight transfer that results.
Clever suspension design may handle it quite well, but to say it is a myth as you did, is just plain false.

YOU may not notice it.

You may not have experienced it, but it does exist.
And, again, it is not manifested in the typical belt car layout.
Ask a helicopter pilot what happens to his aircraft when the tail rotor fails.
