That's a Midwest Strikemaster. It originally was a plan from RCM until Midwest kitted it. I had one of these oh so many years ago. Watch how much elevator you give it as mine had a tendency to snap at the top of a loop. I loved this plane. Once on a deadstick landing I hit a 55 gallon drum and only broke the spinner. Mine was powered by an OS .40 FSR. You are lucky as the .46 you are using is a great engine.
