My intent is to power this bird with a suitable four stroke nitro engine. I'm not sure if a .90 will be too big or not.
For a biplane with only a 59" wingspan (1.5m), I'd say a 90 FS is way too big. Something like the Saito 56 (or the 62) would fly it beautifully.
I'm thinking about simply dropping a servo in each wings and if there are any visible wires that would have been used for this purpose to just model them as dummies to complete the look.
With that nice thick airfoil, I'd definitely put the aileron servos in the wing...unless you just want the challenge of figuring out a closed-loop cable system.
Oh, and I'd go ahead and put the sheer webs in each wing bay (though they shouldn't be needed in the outermost parts of the wings.
