Old C.G. location


I have predominantly been working with older models, the type that used tube receivers, B batteries, escapements, and other heavy items lying forward of the wing. As built this may have worked, but now radio gear weighs in grams instead of pounds.

I find it difficult to balance the model as per the original plan. The estimated C.G. has shifted to the rear. In order to bring it forward again, I shove everything possible right up behind the firewall. On certain models this is infeasible, and looks as if I need to add a goodly amount of ballast in the form of some heavy lead perhaps. For tri-cycle gear models this C.G. problem has effects in that the nose gear does not touch very heavily too.

The thought came, what about shifting the wing towards the rear by up to one inch?

Or worse yet shifting the engine forward more by about one inch by increasing the overall nose length?
