They aren't allowed to send you solo in a flexwing, neither of them is a current instructor and that's been mandatory for the last couple of years.
If it's the X'Air or MW6, best of luck - in my opinion you shouldn't have any trouble with either and it'd be quite legal. (Personally I think that the X'Air is much nicer, the MW6T that Rob flies is, like all of the breed, largely lacking in directional stability and not as much fun).
