Bad idea to weight one tip,when power is reduced you have the potential for a spin to the heavy side. One of the old dethermaliser systems carried a small weight in the fuselage at CofG , a nylon thread tied to the weight and the other end of the thread pinned to the wing tip. When deployed to end the flight the weight was released and swung on the wing-tip like a pendulum causing a spiral dive. The theory was that if the thread was long enough the weight would hit the ground first and aircraft would recover slightly and not spin into the ground with a thump. Lateral balance is one of the most neglected aspects of trimming a model aircraft. It is not uncommon to see a couple of screw-nails in the tip of a model`s wing as a last minute "fix". As Malcolm says dont be scared to modify the nose to get the essential sidethrust, 3 degrees typical, and some downthrust to counter that high wing. Doubtful if anyone will notice.
