These are my plans for a simple profile SU-31 3D aerobatic model. This design features easy tabbed construction so it goes together quickly. This airplane is designed to be made out of 6mm Depron foam but lots of materials will work, you might just have to adjust the tabs.
Additionally, the slots for the motor mount may have to be adjusted, depending on which motor you choose to use.
I designed this model a little larger than my other models, so its certainly best flown outdoors. Also, the use of carbon rods and supports is recommended.
Wing span: 105 cm (41 inches) | Length: 98 cm (39 inches) | CoG location: 5.7 cm (2.2 inches) behind wing leading edge.
Zip file contains full size and tiled plans in A4 and Letter size. Also includes cockpit artwork.
