H-3 Pegasus
Award-winning cantilevered low-wing monoplane designed by Bert Howland. First flew in
1988.
The H-3 is a tube and fabric-covered sport plane with construction
methods comparable to the H-2 biplane. However, instead of strut and
cable-bracing, the H-3 features a cantilevered wing with a design
G-load of +5 to -3.
It first flew with an engine of 28 horsepower, but normally is built
with engines in the 40 to 50 horsepower range now.
The clean configuration gives it a very impressive cruise speed
compared to other very light aircraft. The design won first place
awards in its category at the EAA Sun 'n Fun Fly-in at Lakeland,
Florida in both 1989 and 1990.
The designer developed a war bird variant of the H-3 in 1993, based
on the P-40 Warhawk of "Flying Tiger" fame. It was designated HP-40,
but is not offered now as a separate set of plans. However, H-3
builders who wish to opt for this variant can receive supplemental
drawings to enable them to make the minor changes.
One of those, the substitution of tube and fabric wing tips in place
of fibreglass tips on the H-3, is an option that many builders
choose for the standard H-3.
