The history of the two airplanes are on the forums here somewhere. Mike Gretz spelled it out before he passed away. The Banshee was commissioned by Glenn Sig to Mike Stott to come up with an airplane that would fly like the Chipmunk, as the first run of the Chipmunk was a success for them. So Mike Stott laid the airplane out as you see it ion the plans designed around the Fox .35, and shows no muffler. Next to nothing in the nose allowed for the longish nose moment. I believe it was designed, built and flown before the Dec, 1969 cut off date and first kits hit the shelves after the first of the year. The Twister came later and I don't think either was published anywhere. Either airplane will do well, it just depends on the nut on the handle!! It depends on how well it's built, trimmed and flown. The modifications that are out there for both airplanes work but they DO add a fair amount of weight. Both airplanes are contest proven in their stock configuration. I have related the story here MANY times of a club member here, John Garrett, taking a stock Twister from beginner all the way to expert. I'm not talking about a series of airplanes, just one! He wore out three FP-.40s along the way, all but one of those stock also, I saw him put a whoopin on several piped models with that airplane. He crashed it a couple of times, and repaired it. The last time it was pretty severe, so we pulled the engine from the wreckage and stomped on the rest to discourage him from trying to resurrect it! Some one else had the correct answer, get both! Build them stock and have your own little fly off!
Type at you later,
