The aircraft carriage is constructed from a combination of bolted aluminium and 4130 steel tubing. Inflight steering is accomplished via a weight-shift tilt-bar that actuates the canopy brakes, creating roll and yaw. On the ground the aircraft has lever-controlled nosewheel steering. The factory-provided canopy is an Apco Aviation Ram Air with an area of 550sqft (51m2). The landing gear incorporates independent hydraulic struts for suspension. The aircraft was factory-supplied in the form of an assembly kit that required 50 hours to complete.[1][3]
Reviewer Andre Cliche described the Hercules as "a heavy hauler brute powered by an amazing 110 hp Hirth 4-cylinder 2-stroke engine."[1]
