     THE PORCUPINE

Our Mission

To design safe, comfortable, high performance aircraft that are affordable to build, fly and maintain.


The Porcupine follows in the tradition of STOL (Short Take-Off and Landing) aircraft like the Piper Super Cub. Built from 4130 Chromoly steel tubing and a fabric covered wood wing. Pilot and passenger fly side by side. Imagine the fun of landing on sand bars in a river or taking all of your camping gear and flying to the mountains for a week!
