Good job Rick. I guess we were all on the right track.

So Andy,

what are the specs of the speed 400 version - is that the 35" span version? What's the span of the 40 size? What will the span of the 25 be - around 420-450 squares?

I seem to recall the Shrike having a CF tube spar around which the wing was built directly on to the fuse. I see there are holes in the fuse sides - will you be passing a CF tube through it a single piece model? Good old Dave Brown arrow shafts perhaps?

Rudders will be cool - they could be actuated by a single servo in a double rod aileron configuration with horns on the inside of the rudder. Likewise for the ailerons - a single servo in the fuse with torque rods. I guess with retracts though you could use dual ailerons servos nicely tucked in on their sides.

Progress?

David.
