The UCDs from Great Planes build pretty fast. You don't have to glue the wing which helps. My Mayhem from Sig was easy to build and has great hardware. Everything goes together easy on both of these planes. I'm getting better at the UCD46 because I'm building my fourth. However, I must really be slow because the advertisments say approx 8 hours. It usually takes me about 30 hours. But I don't worry about it because I consider that part of the hobby and enjoy making each one a little better than the one before. All in all most ARF are easy to build. I just wish I was ARF.
Thanks,
Barry
