I am predominately an electric flyer, from smaller parkflier and 3D, to large sport scale aircraft and I have been building for quite a few years. About 2 months ago at work, I was asked by a co-worker to build his Carl Goldberg Piper Cub (76" span) with a Supertiger 61 and Pitts muffler. He has not flown an airplane in many many years, and is currently getting a trainer and building it this fall but planning on learning to fly next spring. Originally, I was to build the plane, with full cockpit scaling and some other touches, break the engine in, make the maiden flight, and then turn it over to him where he is going to hang it in his two-story kitchen space till he learns to fly well next year.

My question is, I can easily see this plane being flown, and having a sucessful maiden, but I am concerned about the engine during storage over what may be a long period of time. Should I break this engine in, make flight, and then let it hang for 9 mo, 12 mo, or longer? I would think that the engine is in good shape now having been factory oiled, with no glow fuel run through it, and that I should hang it up this way with the glow plug and carb capped off to protect from dust.

Any thoughts would be appreciated.
