Yea but, SOMETIMES my landing speed is much faster then my stall speed!!! Need a brake in the air, not lift. If the under belly flap helps out to slow her down to almost a stall speed it will be more then I was lokking for in this simple to use and make setup. PS. ITS NOT ALL FOR FUN!!! Am trying to learn from experence and wisdom from some of you old time modelers who I, and I hope many others tip our hats to. Just think, the next generation gets to learn about innovations from from,from, YES AAARRRRFFFFEEERRRRSSSS. So guess thats what I am wanting to do. Use conventional wisdom with out the computer radio. Love simplicity that is well executed in planes.After this project is accomplished this winter, will be moving on to my next one which is already in the works. OHHH BOY!!! You guys are going to love this one.Imagine this. Ceramic screens fitted on the end of your muffler that heat up and burn unburnt lubricant residue to keep your plane forever clean, AND give a free by nature a smoke trail. So far I found I need more heat from the muff. Could get it from a battery operated glow device I imagine on the screens. A engineer suggested a horse shoe type muff to restrict and generate more heat. By the end of the winter this sig midstar for sure will be like no other. KELLDOG
