Being only 260 pounds fully loaded, with an impressive 60 horsepower 2-Stroke made into a 1->2 gearbox ratio into to a 3 bladed aluminum prop, this amazing bird gets an inane power to weight ratio of .24/1. An impressive top speed of 75 Mph and a stall speed of 27 Mph. Nearly doubling the speed of a regular ultralight. However, this, is no ultralight. It is the combined work of 1 year, 3 planes, and 52 massive failures.
I present you,
