Here are Flying Models MPS 138 plans for the Bill Simmon's P-39 Aircobra.. this was his first published design .. this is a classic legal design.. I still don't know how this thing flew with a Fox 35 .. it sports a 56" WS ... Bill tried to keep these designs in the 48-50 ozs ... if you can build this in the 45-46 oz range an LA 46 should pull it along OK .. if not choose a bigger engine set up for stunt..

I was able to find the article online and posted it here .. I had to work for this info.. there isn't a lot of info on this plane .. his Shoestring is more popular of a build ...

I will combine shipping
