Glanville GA 2C Skymaster Gyroplane

A Variation Of The Hollmann HA-2M Sportster

ARTICLE DATE: October 1979

BACK IN 1976, C.A. (Kemp) Glanville, president of EAA Chapter 112 in St Thomas, Ontario, Canada, and his two sons, Mike, 22, and Ed, 15, bought a set of plans for the Hollmann HA-2M Sportster gyroplane. Within a year, working on it together, they had it far enough along to take their new GA-2C Skymaster the annual Popular Rotorcraft Association convention at Rockford, Illinois.

But — they got there the night the show closed, due to confusion in dates, so off they went to Oshkosh with their fun machine, which proceeded to win them a couple of trophies. Being Canadians, they decided a few changes were needed to make the Hollmann gyroplane suitable for cold, winter flying, so they completely enclosed the cockpit area.

Glanville decided that the changes required a new name for their rotorcraft, and they christened it the Glanville GA-2C Skymaster Mods included steel disc brakes on the mains and re-positioning of the fuel tank to the CG. so that the tankage can be increased without disturbing the balance on burnoff.

Father-and-son homebuilding team, C.A. (Kemp) Glanville and Ed, 15, pose with their Skymaster at Oshkosh ’78.

The aerodynamic clean-up of the canopy, they estimate, will add 20 mph to Vmax and cruise speeds. They also added an electric starter and external power supply. In addition, they fitted their Lycoming 0-320 of 150 hp with a VW oil cooler to the GA-2C Skymaster.

The next problem was learning to fly their whirlybird, so father and sons drove their motorhome down to Paducah, Kentucky, where Don Farrington runs a rotorcraft flight training operation. Farrington got Mike all checked out in three days.

By last November 14 they’d won full DOT approval for the GA-2C Skymaster in Canada, and began logging time, making some 50 crosswind landings Kemp said they discovered that the basic Hollmann design, as modified, handled far better in a cross-wind than any fixed-wing aircraft he’d ever flown.

At last report they’d added a new fin and rudder combination with smaller surface area as a cosmetic change, and were at work designing a prespin jump-takeoff rotor head for the GA-2C Skymaster. The Glanvilles, of course, visited Oshkosh again this summer to show off their fancy bird.
