Here's a buddy (Andy Woerner) and his scratch built minimum diameter powered with an M2500...on its way to a 28,500' flight and a succesful recovery. Andy is the owner of Polecat Aerospace and What's Up Hobbies, the largest HPR retailer in the US. Andy is also a very active RC pilot here in San Diego.
