Ran across this new design being developed that would make an excellent scale subject. I don't like the hassle of retracts in any plane but do love twins. Looks like good moments and a large rudder which always makes for good twin performance.

very nice looking.

Here is another noce fixed gear and forgiving twin to consider!

Looks like a Shortz but I don't recognize the model. Would indeed make a nice model!
