G'day Flyboy,

Yes add weight to the wing tip to laterally balance. Your plane will fly nicer.

The article about putting weight in the right wing tip to counteract propeller effects (spiral slipstream and offset thrust, not torque BTW), is generally accepted as rubbish. It would only work while accelerating during the initial part of the takeoff run and have no effect once speed had stabilised, whereas rudder is needed for the final part of the takeoff and climb. The tip weight would adversely affect the entire flight and landing.

Better to use the rudder to keep straight, that's what it's there for.
