RE: Should an ARF go together so fast?
I built the .40 sized Ultra Stick, The hardest part was folding a 3/4ths inch wide strip of covering in half, so I could seal the hinge gaps. I used the flapperon version, instead of the separate flaps/ailerons. This added a whole new dimension to this plane's use. I crashed my stick at the end of last season. I will have another soon. If I had a .90 four stroke, I'd go with the .60 size, like you did. I'll power mine with my new O.S. .46AX.
I found the UStick to be a great airplane, easy to fly and assemble. This ARF is of extreme high quality and I have nothing but praise for it. I think the .60 sized is even better that the .40. I could see myself always having an Ultra Stick as a knock-around plane for everyday flying. I hope Hanger 9 keeps producing them!
