This would be a great project !
This could be an alternative route....
the Hog bipe looks so much like a 4 star fuse with two wings, I would just by me a 120 size 4 star and a spare wing kit. then change the formers to cheat it out
Of course no need for that if you like blowing up plans and cutting kits.
I have no idea why the 4 star has never been offered as a bipe?
years ago in the local club a guy built an 80-90 inch wingspan Smith Mini Plane, wow was that gorgeous !
I sure like seeing these threads where people are thinking off the normal course.. makes me feel less alone
