RE: GP minnow/OS91 surpass..what prop
100mph is great for fast sport flying. You have a very nice engine/plane set up, I say just fly the crap out of it and have a blast. I saw the toni flying at my field one day and was very impressed with how well if flew high speed aerobatics. If the minnow flies as well as the toni I know I would have a blast flying it, and looking at the design it looks like it might fly even better.
