I think Koli is exaggerating slightly :0)
Although, I do like to demo the aircraft to its full potential. Strangely, there doesn't seem to be a massive amount of advantage to back side of the curve approach in the Koliber/Rallaye. I think that the drag increase is so dramatic in the flare that it does the same job as waffling in under a touch of 'puissance'!
Hover-taxiing is also a bit of a giggle - especially on a quiet day at EGSX. I've tried to land going backwards in a strong wind but never managed it (nagging notion that it wasn't a good idea based on the fact that I've never managed to push any Koliber or Rallaye backwards without a tow bar).
Having flown some serious STOL machines I don't know of any aircraft which has such accessible short field performance - ease of use is the issue, really.
Koli - You have my email, just drop me a line whenever you want to do some more flying...
