I see no point in building two engine mounts. Do a complete W series without the engine, complete with fuel and pilot and passenger, and then determine the engine location using paper and pencil. Use the center of mass of the engine for the moment arm and don't forget the weight and arm of the mount, cowl, prop, spinner, battery, etc. The front two or three inches of the CG range would be a good target with pilot and fuel if adding a passenger doesn't move the CG beyond the aft limit.

Yes I can. Do a weight and balance calculation with the engine off, then put the engine on and do another one. Now calculate the moment of the engine. Then move that moment to where the plane is balanced and that is where you put the engine. See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2011 - KR Gathering in Mt. Vernon, Il - MVN There is a time for building and it never seems to end. Daniel R.

I made everthing in one piece like the picture. Someone told when you are 90% finish, you have 90% to go, these word just fit in here. But the shape is finish, and been very nice. So I just have to put carbon on it etc. I will use one UL power at 107 hp and weight only 159 pound+oilcooler. I just love this engine. I want to have any fuel in my wings, so I have a question I hope someone can help me on. The fabric who deliver the engine will make a engine mount for me. The fuel tank in the front is removed and the engine is lighter, how far forward do I have to bring the engine to bring the right CG? Hope someone can give med some good idea how to calculate problem like this? Regard Leif G Alstadseter
