I had the Flatana and then designed my own foamy with SFGs similar to hte Turmoil. First off, take your time with the build. THe hinges are a pain to use but once all set up work flawlessly. Also, either build it without the landing gear, or if you put the gear on, reinforce the area where the gear crosses through the fuselage with a couple strips of packing tape. THat'll help keep the gear from ripping through the fuse. As for the SFGs, I leave them on my designed foamy all the time, and I only fly outdoors in a good amount of wind most of the time.
