I would like to know if anyone has some pictures or hints on jigs for balancing giant scale planes. I have an 84" w/s biplane, as well as a scratch-built 1/3 scale Pitts. I want to be able to build up a jig that i can get under the top wings with to accuratly set my c of G.

This is just the start of the big planes, so if I can use this jig to set the C of G on monoplanes as well would be of great benefit.

Anyone have any hints or tips..??

Thanks guys...Don H.
