2 SETS OF PLANS IN ONE!

Build either the wind-powered B-19 Glider for as little as $500, which needs no engine and is towed into the air like a kite; or the engine-powered B-20 Kopter, a self-powered aircraft capable of long, sustained flights. Vortech is pleased to offer the complete plans for building both outstanding aircraft.

FLY FOR FREE . . . with the B-19 Glider . . . OR FOR PENNIES! with the B-20 Kopter

The Glider costs nothing to operate, requires no license. Towed by car, the craft becomes airborne at about 23 mph. Flight is completely pilot-controlled, limited only by the length of the tow cable. Or, by adding a cable release, once airborne the pilot may free the craft for the exhilaration of unrestricted soaring. The B-19 may easily be converted at any time to the B-20, as is fully detailed in the same Construction Plans. Take-off and flight of the Kopter is under full piston-engine power. Takes off at 30 mph. Cruises at 60 mph, with a high speed of 85+ mph. Climbs at 1,000 fpm and will reach an altitude of 12,000 ft. Engines of as little as 35 hp may be used (with reduction drive), or up to 80 hp. If flown as an ultralight, the B-20 is free of licensing or certification requirements. B-19 easily converts to B-20—detailed in Plans!

SUMMARY OF THE DESIGN:

The above 2 aircraft are the unpowered B-19 Glider, which can be towed into the air by an automobile or, if fitted with floats, by a boat. Once airborne, the cable can be released and, with proper skill and perhaps some help from the wind, the craft can continue its flight for many minutes. Once control of the glider has been mastered, the craft can be easily converted to the engine-powered B-20 Kopter. According to FAA statistics, gyroplanes have outstanding safety records.

SUMMARY OF THE PLANS:

Construction of both the B-19 and B-20 are fully detailed in our plans package, available in either a reduced format (11" X 17" manual) or as full-size blueprints with an assembly manual that provides step-by-step layout, parts’ descriptions, balancing, and so on. The full-size plans includes 3 free bonus manuals: Flying The Gyrocopter, Flying The Gyroglider, and the Helicopter Experimenter's Handbook. BUILDING COST:

Cost of constructing the B-19 can be as low as $500, or, for the B-20, as low as $1,000, final cost depending on sources of supply, cost of engine, etc. Even such critical parts as rotor blades, rotor hub and joystick may be constructed in a home shop from readily available raw materials, as detailed in the manual.

LICENSE-FREE STATUS OF THE B-19/20:

No license is required to fly the B-19/20. The unpowered B-19 is classified under Federal Aircraft Regualtion (FAR) 103 as an unpowered, ultralight aircraft since its empty weight is below 155 lbs and it is only intended to carry a single person (the pilot). To fully conform to this regulation, the Gyro-Glider must only be flown for recreational purposes during daylight hours in an area away from concentrations of population. Even when you add an engine to the B-19 and create the B-20, it would fall within the weight criterion for a powered ultralight.
