i have built two of them they go together in about a week if you work a couple hours a day,i put the Irvine 53 on mine that makes it really hot when you want to switch to high rates.i would suggest installing the rear wires on the tale with that engine.on high rates with those large ailerons it will do about 3 spins a second.ans slowed down on low rates it will float in.i wouldn't put on the wheel pants if you are gonna take off on grass they wont last long.and the wing i have seen a few people here use screws or plastic ties, screws you need to modify the wings some.i have some photos of the second one i built i will try and post them for you.hope this helps some....happy flying
