I built one for a freind 2 years ago. ame 061, 3 hs-81. flew great, hand launched great. we set it in the grass, and it would take right off of it. We had a little problem r.o.w. without chines. bent some out of an aluminum can and servo taped them on, and r.o.w. worked then! everything about kit fine EXCEPT- thin canopy plastic wrinkled in the sun!!! would recommend buying k+s sheet and making your own, or just sheet and cover w/ black. hope this helps.
