The H5 is a development of the Hummel Ultracruiser Plus and has a gross weight that is heavier than the original Hummel Bird.[2]
The H5 features a cantilever low-wing, a single-seat enclosed cockpit under a bubble canopy, fixed conventional landing gear, or optionally tricycle landing gear, and a single engine in tractor configuration. The cockpit is 24.50NaN0 wide.
The aircraft is made from sheet aluminum. Its 22.51NaN1 (optionally 251NaN1) span wing employs a Harry Ribblett GA30-618 airfoil and has an area of 100square feet. The aircraft's recommended engine power range is 60to and standard engines used include the 60to Volkswagen air-cooled engine four-stroke. Construction time from the supplied kit is estimated as 420 hours.
By December 2011 twelve examples had been completed and flown.
