I haven't built one myself but know someone who has. A member of my RC model club helped his son with it. Working with the composite materials made him ill so the son finished it himself. He's since flown in it many times & tells me it's great fun. I think it's a delightful little aircraft.

PS. The last I heard he wants to sell it in order to purchase another kit & start again. This time a replica Spit like Ozzy's. I think the Jabiru would suit me better.
