RC Plane – SU-29 1100mm

The SU-29 is perfect to learn 3D aerobatics without the fear of crashing an expensive model. It is a semi scale design with a vast fuselage side area, assuring a perfect knife-edge flight.

The wings are detachable for easy transportation in small cars or while your next vacation trip. Its low weight and wing loading makes it easy to fly in tight spaces.

The design is optimized for vase mode printing.

If you would like to support the project and help to make future projects possible, I would be happy about a donation on PayPal.
