I'm running mine with a Super Eagle, plenty of power and a drop in installation. Ditch the bottom half of the by-pass, the half facing the wing, and you'll notice a nice thrust increase. No need for crow with the Flash, it has a good sink rate with no tendency to float on approach. Reduce the full flap setting 20-25 mm and make sure it is balanced per the manual. Not an incredibly fast jet but it flies on rails!
