I don't know if you're pulling my leg or not,but..
some reasons a Running the engine gives a lot of personal satisfaction; debugging the instrumentation and operating parameters as actually connected to the planes panel and not on a test stand; something to do while awaiting parts, whatever; can figure out exhaust and mufflers layout; can figure out cowling fit; can solve any heating/cooling problems; etc, etc.. Boils down to my project and whatever makes me happy G "guynoir" wrote in message ... I still don't understand why you want to break in an engine on a non-flying aircraft. What's the point? You're going to have to finish putting the aircraft together anyway, and it will probably be days, weeks or months between the assembly and actual airworthiness. Why not run the engine then? Dick wrote: Midget Mustang, single seater experimental. There are 2 other planes crammed into the hanger and having wings installed is not an option at this time. The builders on the field have broke-in engines on a fuselage without wings several times previously. Safety of course is most important. I find builders innovative and some, basically cheap (myself). Hence the 2x4 approach. Although my stand has no duct tape, we did race a formula Vee back in the 60's and sometimes used duct tape for securing body skin at 95-100 mph.. -- John Kimmel Naturally, these humorous remarks are all entirely my own opinion, based solely on rumor, supposition, innuendo and damned lies, and should be interpreted in a spirit of fun.

Your reasons for running the engine suck. A proper, deliberate and
methodical approach to finishing your aircraft will result in a finished flying aircraft in the minimum time and with fewest problems. Disasters like the Skystar incident are rare, but pursuit of instant gratification is all the invitation needed. I agree with your reasons for having the engine mounted on the fuselage. You have already figured out a way to support the fuselage with the engine on it, since you have the fuselage completed and the engine is mounted on it. It seems to me that there is no obstacle to your completing the aircraft. Final debugging can be done with the wings and landing gear installed, as has been the usual practice for everyone else who's ever built a midget mustang or mustang 2.

I was originally going to suggest making a structure that would bolt to
the ends of the main spar fittings, but that could impart stress on those fittings that could damage them. The bed/carpet sling idea is OK, except that you will be running the engine, not just moving the assembly around. How about making a wood structure that "sandwiches" the wing stub ( say about a foot outboard of the fuselage sides ) Think of the "clapboard" that the movie industry uses before each "take" of a scene. Cut out the shape of the airfoil between (2) 2 x 8's. Hinge the 2 x 8's on one end and bolt them together on the opposite end. Then extend a vertical board on the forward end of the structure and put casters/wheels on the end. You could arrange the casters far enough forward that you wouldn't have to add weight to the tail with the wings removed. Make one for each side and maybe secure each structure to the other one for rigidity. Of course making the whole thing stout as hell and protect the wing. Might work. Neal |

Neal,
Leaning towards a stub-out wing section with permanent gear mounted. This allows me to: complete braking system; still fit project alongside my flying plane; continue folding wing mechanism developement; etc. Thanks for positive thoughts, Dick wrote in message ups.com...
