Trouble at the hangar.

Last year I was given three O.S. S-35 engines. I didn't really have a need for them at the time. I also got 2 more Brodak .40 engines that came to be a real good engine for my small designs. I put one of the 40's in my Jamison old time stunt plane to replace the heavier more powerful LA .46. Then I won a kit of the Dee Rice designed Oriental. I never had one and it turned out to be a good flying plane. The plans show a Fox .35 engine whick is very light at 6.5 ounces. The LA weighs around 9 ounces. The plane camne out quite light at 40 ounces so I decided to install one of the Brodak .40's and remove the LA .46. That was just what the Oriental needed as the performance improved quite a bit. Then I got the idea to install one of the .35's into one of the small models, my design "Wild Thing".I flew that and it's another winner. The local hobby shop had a kit of the Oriental on the shelf at about half price so I bought it. I'm about half way through framing it up and I needed to install the engine to move along with the fuselage. I amd going to use the Brodak 40 in this plane so I went to the Jamison that I had put one in and removed the engine and installed it in the Oriental fuselage. A couple hours later i remembered that I had removed the Brodak and installed a .35 in the Jamison and them used it to mark and drill the mounting bolt holes. I didn't realize that I was using the wrong engine until too late. When I got home I removed the brodak from the first Oriental and fitted it into the new Oriental. Luckily the holes are the same for the O.S. 35, the LA 40/46 and the Brodak 40. Even the spinner clearance is good for both engines.
