I'll try and answer all of the questions
1) This is the #1 prototype from FB direct, the quality is very good, the construction is very similar to COMPARF, I ran a bore camera down the wings, and tail surfaces to inspect. I was happy with what I saw.
2) No price set yet as far as I am aware, Cathrine to comment!
3) I think the photo may be an optical illusion on the gear stance, the fuselage is over a foot in diameter, and the retract units are inset into the wing, I can get a gear stance measurement tonight
I did not have any concerns that the stance was narrow at all.
Update:Main gear stance is 26" (66 cm)
