Hey Mike,

Has anyone tried rigging up a sliding weight on tracks in a model F14 or F111 that is shifted by a worm drive or pulley arrangement? It seems to me that this would be the best solution to the c of g shift issue. Movement of the balancing weight could be mixed to the wing sweep channel. I don't have the electronic knowledge to set it up but I am sure it would not be too hard for someone who does.

Hang on.....maybe I do. The counterbalancing weight "trolley" could be shifted on bearings by a pulley arrangement hooked up to a model yacht sailing winch....plenty of power and precise control already engineered into it. I know this is off topic but Andy N. mentioned that you had an F111 and I was curious to hear your experience.

Regards,

Craig.
