RC Beginner’s Guide: Understanding Torque Steer
Now, I won’t bore you with the technical aspect of torque steer. To put it in simple words, since the rotation of the drive shaft is perpendicular to the wheels of the car, the torque delivered from the motor has to change direction several times before it gets to the wheels. What this does is that it causes the chassis to have the tendency to slightly steer itself to one side over another. Try setting your shaft driven car on the floor and let it run without steering, you’ll notice that it’ll start to steer to one side automatically, or if you’re drifting, you’ll find that it’s easier to drift one way compared to the other.
So why won’t belt driven cars suffer from torque steer? It is because the drivetrain is inline with the wheels. The pulleys are parallel with the wheels and motor rotation. Torque is delivered evenly and in the same direction, front to back, and only needs to change direction once at the pinion and spur.
Given the nature of shaft driven chassis, reducing torque steer is still achievable by adjusting your setup. However, some just ignore it since it lets you drift easier.
