Very cool,
what motor will you be using?
I built a Ringmaster a few years back that weighed 19.7 oz. Dyed silk on the wings with a full blown painted fuselage and tail feathers. Powered with an OS .15 FP.
I let Jim Aron fly it at the Golden State Stunt Championships and he beat me with it. That's why I don't let other people fly my planes in contests any more.

looking forward to knowing the final weight and how she fly's
