Wing Panels on Sig Mustang Stunter

I have a kit for the Sig Mustang Stunter that is still in a sealed box, so I'd rather not open it just to check this feature. Can anyone tell me if this plane has wing panels that are equal length, or is the inner wing panel longer as on many stunters?

Bob If I remember right it is equal span wing and it is not cored out. Which will make it a little heavy. I would use a la46 for power and core the wing out and mold the plastic parts. Alan

Correct. The inboard wing has two holes drilled in it for the leadouts. It is easy to core this using the two holes for access for the wire. Don't worry so much about the outboard wing as it adds to tip weight. The wing tip blocks are thicker than needed and can be turned over on their side to increase the span another inch. then use the plastic turtle deck to mold a balsa shell. I would also make a balsa cowl rather than the plastic one since I never figured out how you are supposed to be able to choke the engine with that one. We turned the motor mount over the mounted the engine upright. It actually doesn't look all that bad (think of Al Rabe's Mustunts) and is much easier to choke that way. If so, you can just glue the plastic nose cowl into place. It is not a bad flying airplane if care is taken (as is needed with any airplane). Add adjustable leadouts, adjustable tip weight, tail weight box (if you put one in, you won't have to put anything in it. Murphy's law). go for it.

I have had two of the SIG Mustang Stunter. The first one was ordered as soon as I seen the ad. It was built box stock and powered with Fox .35 Stunt. Weight ready to fly was 41 ounces. It met its demise after about a dozen fights when the bellcrank mount came loose from the foam. Hey it was my first foam wing.

I then built a second one as I liked the first one so much. When I put the bellcrank in the wing I put plywood top and bottom in the wing. It too was powered with the same Fox .35 Stunt. It weighed about 45 ounces as I put too much finish on it. Did have a gear leg knocked out when I hit a hole flying over grass.

Using an LA 46 is over kill and would make it seriously nose heavy. Tod Lee flew a highly modified version of it for several years. I think they added length to the fuselage. Replaced all the plastic and cored the wings. It had one of his gorgeous finishes also. You can contact Jim Lee and find out all that they did to the kit.

The design as is is a good flyer, but, not a world beater without some mods. Just remember to put in proper bellcrank mount.

FYI - I have a Sig Mustang on Ebay now (item # 300305216031). The wing panels have been cored. You could bid on this one and preserve the sealed kit for collecting. Or, if you decide to sell yours some day, sealed kits generally go for a higher price. Regards, EWP

My Sig Mustang has cored wings and all the plastic pieces (except the canopy) replaced with hollowed balsa blocks. I also extended the tail moment 1/2". Weighs 40 oz and flies pretty good with a Brodak 40 in it. I should have given the stab/elevator another inch of span too, but oh well.

Good looking Mustang. Flip the engine over and it could pass for one of Al's Mustunts
