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.

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.

The Complete B-19/20
Plans
comes in 2 sizes:
Our plans for the B-19/20 in
either size format are complete, clearly drawn and detailed, and
include full plans for building the rotorblades as well.
