FMS beginner and warbirds RC plane - Motor Shaft is not centered / RC plane Dutch Roll / Torque Effect

The motor shaft of the FMS propeller plane is intentionally angled to the lower right. This design choice helps mitigate the torque phenomenon, a common instability in aircraft that involves a combination of yawing and rolling motions.

What is Torque Effect?

This phenomenon can accelerate your crashes. When the propeller rotates to the right, it generates a force in the opposite direction, which we call "deadly torque effect."

So how do you counteract torque effect? Look closely from the front, and you'll notice the propeller is angled slightly to the lower left.

This is actually to offset some of the torque. Torque effect generally appears during the takeoff phase when the aircraft hasn't yet reached sufficient speed, and pulling up too early can be problematic. Therefore, make sure to gain enough speed before gently pulling up.

If your plane is in a near-stall state and you suddenly throttle up, it will generate significant torque effect also.

One suggestion is to place the ESC and receiver towards the right to counterbalance the torque effect through weight distribution.
