The Black Belt of Slope Soaring

The Japanese Ninja is a master of all the oriental fighting forms. We've given the name "Ninja" to this slope soaring glider because of its all around ability to excel on the slopes.

The Ninja was designed to be the ideal model for your first try at aerobatic slope soaring. It has the aerodynamic shape you need to penetrate the strong winds present on the slope. The Ninja wing uses the Eppler 374 airfoil because of its fast speed, gentle stall characteristics, and excellent aerobatic performance. Loops, rolls, spins, and inverted flight are routine and easy with the Ninja.

Easy To Build Kit

Modelers who value their flying time want to spend less time in the workshop and more time on the slope. The Ninja has a foam core wing, a die-cut lite-ply fuselage, and sheet balsa tail surfaces to help you get it in the air quick.
