You may want to make a few mods while you build it. I would suggest adding some 1/16x3/8 balsa strips to the inside of the wing sheeting. Also you may want to increase the size of the rudder/elevator if you ever plan on trying to hover. Replace the stock tailwheel too. Lastly if you don't already have the engine, you should check out the Irvine .53. I've got a .61 on mine but I still wish I'd gone with the .53. I've heard nothing but good things about that combo.
