Hi George,
This is some good progress! :clap:
Ok, for the rudder, mine use closed loop cables, but you can use Robart snakes if you prefer, but I would personaly use cables. They exit by the holes at the end of the fuselage.
For your drawing, 90 degrees on the right : Yes
Don't mind the cuts (lines) that are on the 2 long pieces named N1. They are for the Laser Cut kit!
Now, talking about these 2 parts, I just realized that I did not name them right and placed on the plan! :oops:
If you look carefuly at the plan and the pieces, this is easy to find which one goes where : the notches on the ribs will match the correct piece if you see what I mean.
Material is : top one on the plan : 2mm plywood (that's the piece that is the ailerons LE)
Bottom one : 3mm plywood (that's the piece that go at the end of the ribs of the wings)
This bad drawing should shed some lights

Let me know if there are still parts that are unclear.
Fred
