I have a good flying buddy that finished his up this spring. It flies AWESOME, but has some small problems as most kits do. He started off with an ASP .75 and that engine really sucked, he couldn't get it to run right. He then went with an old Trusty OS .91 Surpass and it flies very scale, plenty of power. I think a 1.20 would be Awesome! I have flown it a few times, and enjoyed it. As with all WWI tail-draggers you have to be right on the rudder on take-offs. It lands very nice, floats in. He has had a TON of problems with the tail wheel/skid, he kept tearing the whole thing off including the rudder on landings. When the small wheel/skid hits anything on the runway, small hole, rock, etc. We have a very rough field, so I am sure that is the problem. You wouldn't have this problem on pavement or smooth grass---- But be sure to pin your rudder hinges and use good 1/4 hinges-DO NOT use CA type hinges, unless you love them! LOL I am not sure about many scale things he did, except for the options on the plans. He enjoys it, and here are a few pics. He used the Flat Monokote, and it is OK, it is very brittle, and in cold weather it will break like glass, if you get a rock or bump the thing. It was a builders kit, typical of Dynaflite , very nice. He had no Real problems building. I would love to build one in time, but I already have my winter project already dusted off! Hope the pics help. Good Luck! Happy Building and Flying!!
