Here in the USA Ikarus' are in the category of Light Sport Aircraft. To fly a LSA you need a sport pilot license which are almost as difficult to obtain as a Private Pilot's License, but you can fly w/o a medical certificate VFR day only. I've flown a few homebuilts w/ Rotax engines and the amount of power fom 5 gals/hours is amazing. I'm sure you had some fun. O'Neille
