Default 18% Fokker-D23 Project. HELP

After more than a decade of procrastinating I am going to build an 18% Fokker D-23. It was Anthony Fokker's last fighter design. I am working from Fokker Heritage Trust original photos, drawings and plans (For which, I am in debt to Rob Ercavich (sp?). A Dutch modeler. Thanks Rob.)

http://www.dutch-aviation.nl/index5/...5-1%20D23.html

This is the largest model I have attempted and I expect the learning curve to be considerable. Those of you with experience in scratch building large scale can be a great help in keeping me out of dead ends. Please help?

The basics:
Wing; 82" span, 995 sq in. 22% nearly symetrical root, 16% semi-symetrical tip (from Fokker blue prints)
LOA 71" Twin boom, Pusher/ Puller
Powered by two four stroke pumped engines
basic construction is glass coated, balsa sheeted foam (8 yr.s of combat foamie construction experience. One of the few things I know how to do.)
6 ch. and 11 to 14 servos depending on gear door actuation.
Pretty close on to 150 oz of gear in it (engines, servos, retracts, batteries & etc.)
I am using TurboCadLE (2D)to draw the plans.
Now for the first few of many questions.

Would anyone care to venture the all up weight range?

I have a good YS 120 kicking around the shop. Would a pair of those be too much, to little or just about right?

I tried to attach the first rough draft of the plans but RCU doesn't "support" TurboCad's format. Well this could get wordy.

Thanks In Advance
