The main issue was the fact that the distance between the main wheel and the original tail wheel position was quite short - with the rotax engine take off performance was very brisk and - compared to the falke - quite a high threshold speed (65kts) for landing. Basic geometry would also suggest that the tail wheel being closer to the mainwheel gives a marginally greater deck angle, there is a mod which most of the fleet have incorporated which moves the tail wheel 6in further back Which apparently makes a big difference.
Someone at my club is building a motor glider version and I'm looking forward to comparing it to our "I can't believe it's not an XS".
Oh and the Europa one of the types the LAA were trailing for approval to fly in IMC. Though if the conditions are so crap you've resorted to an ILS to get down I wouldn't particularly want to be in a mono wheel for the eventual landing!
