Thanks all for the kind comments!
To answer some questions:
The "25" on the wing is the year finished. That and the grey are nods to Bob Gieseke, who did so on a lot of his Bears.
The changes (I can remember) from the Tom Dixon plans were:
> Increased the stab/elevator size to 20% of the wing (I believe I added half an inch to each dimension)
> Moved canopy back slightly
> Fixed the rudder shape
> Slightly less taper to the fuselage side
> Changed the cowl shape. The plan has a smooth, SV-style cowl while the actual KA-10s had a more complex shape. However I did not completely replicate the real KA-10's 3-cutout intake.
> Per Kolesnikov's instruction, shortened the nose half an inch (his homebuilt engines were very light)
And yes, I'll be at the NATS, flying this thing in Advanced. I can't wait!
