A side view of Steve Hillman's SIG "Hog Bipe".

This is Dr. Steve Hillman's newest airplane.

It is a 60 size Great Planes Tiger Moth (ARF). He is using a Sato 100 for power. Steve added ailerons to the top wing, this increased the roll rate significantly. He also added Side Force Generators between the interplane struts, which (theoretically) allows long smooth Knife Edge passes. He flew it for the first time this morning and everyone was impressed!
