whell here it is

this is just a dry fit. I know the elev and rudder look small but I think they'll be okay.

Foam rules

Well you can try it but I'm betting the rudder will need to be alot larger as you are small to begin with and than the nose is rather large which means it should be even larger. The horizontal is also on the small size compared to wing area. On a biplane a good place to start with the horizontal area is at least 1/3 of the largest wing and vertical area at least 1/2 - 2/3 the horizontal. With a large nose area the vertical always needs to be enlarged as you need at least twice the flat area behind the balance point as in front.

that's a pretty easy fix. I might try it like this just for CG toss to see what happens no electrics. It's easy enough to enlarge the elevator and rudder as it's not done yet.

This is not to be a 3d plane just a slow flyer
