Glass Goose
The Glass Goose is an
all-fibreglass, two-place, side-by-side biplane amphibian with a
retractable tricycle landing gear and an upper-mounted pusher engine
utilizing a 62-inch four-bladed Warp Drive prop. The flaperons on
each of the four wings all serve as both flaps and ailerons. The
wings are built as one piece and are not removable once installed on
the fuselage. There's a water rudder on the bottom of the air
rudder. The rudder is controlled by a conventional cable-and-pulley
system, while the elevator and flaperons are controlled by push-pull
tube systems. Some of these tubes are aluminium, others are
stainless steel. All of the weldments in the aircraft are stainless
steel. The gear is hydraulically actuated via an electric pump. The
main gear are attached to the underside of the lower wing and
retract up under the wing in a trailing pod. Retraction and
extension are accomplished in about five seconds. The main gear have
two tires and wheels on each side, and the Matco hydraulic disc
brakes are a part of this assembly. With the two tires, the plane is
able to negotiate over soft-sand beaches much more easily, and in an
emergency, should you get a flat, you can operate on the other
single tire. The nose gear retracts in a forward arc up into the
nose of the plane, and the nose-gear door closes over it.
Glass Goose has a very large amount of baggage room.
There's a big baggage area behind the seats between the wings, and
there's that much more baggage room below the lower wing! There's
even additional storage under the floorboards and seats for stowing
such necessities as an anchor and rope. (The paddle goes behind the
seats.) Seating in a semi-reclined position with your feet out in
front is very comfortable. The cockpit is 42 inches wide, and head
room is more than adequate, even for very tall people. The canopy is
hinged at the back. The front lifts up aided by gas lift-struts and
affords plenty of room for entering and leaving the cockpit. The
instrument panel is mounted in the canopy and therefore lifts up and
out of the way when the canopy is opened. On hot days, it's
especially nice to be able to open the canopy while taxiing on land
or on the water. This also makes the back of the instrument panel a
dream to work on--you can do it easily while standing alongside the
airplane. The sponsons on the sides of the fuselage are meant to be
walked on and can be utilized to gain easy access to the engine and
when returning to the plane from the water after swimming. To dock
the plane, you simply nose the plane into the dock and step over the
nose onto the dock.
Four 17.5-gallon fuel tanks, one in each wing,
provide a total of 70 gallons capacity for a range of 1,200
miles--phenomenal for a plane of this size. Scott's Glass Goose has
actually flown from Dallas to Oshkosh non-stop--a flight of slightly
more than 1,000 miles. Fuel tank selection is handled by three
electrically-activated fuel-selector valves. The switches are on the
instrument panel directly in front
the pilot
and passenger. Indicator lights and the position of the switches
show exactly which tank is selected. The instrument panel has plenty
of room to handle full IFR and the plane is easily equipped for
night operation. Visibility from the cockpit is fabulous.
The Glass Goose kit is supplied as follows: A boat
section (forward fuselage) with the two pre-moulded halves of the
fuselage are already joined at the factory. The empennage is in two
pre-moulded halves. The wings come as top and bottom pre-moulded
skins, 27 feet long. The spars, ribs and leading edges are pre-moulded,
and the builder only has to do the trimming
and cut out the spars and ribs prior to assembly. The pylons,
vertical fin, engine cowling, spray rails, scuppers and all the
bulkheads for the fuselage also come pre-moulded. The flaperons are
available pre-assembled. The horizontal stabilizer, elevator and
rudder are made using the hot-wire method and the templates
furnished in the instructions. The wheels, fires, brakes, lines,
cables, pulleys, bolts, nuts, washers, cotter keys, weldments,
cylinders, hydraulic pump, epoxy, fibreglass, tubing, etc., are all
furnished in the kit--almost everything to build the structure of
the plane itself, less the engine, instruments, paint or related
items. For the most part, the builder trims and fits parts to their
mates, then joins them with strips of fibreglass tape and epoxy. The
company trains the builder in the processes at the time of purchase.
Quikkit applies a material called Peel-Ply to all
possible surfaces. When the builder removes the Peel-Ply, the
surface is clean and bondable, thus eliminating the need for
preparatory sanding and the associated work and resulting dust.
Peel-Ply is just one of the many refinements utilized by Quikkit to
greatly reduce the build time for the builder. Another is the
incorporation of extensive "joggling" that also greatly reduces the
amount of finish work during the completion of the aircraft.
Remembering that the original wouldn't take off from the water,
Scott's Glass Goose has solved all these problems. I asked him to
describe in detail the technique he uses for water takeoffs. He said
that the Glass Goose is a delight on the water. For a relatively
small seaplane, it can handle waves much rougher than most--a 10- to
12-inch chop won't even phase the Glass Goose--and it has been known
to handle much worse. From idle power, as the pilot applies the
throttle, the nose of the Glass Goose rises immediately as the hull
begins to climb the water in front of the plane to get on step. It
seems as if the plane is rolling up onto and over a log as the hull
crests the bow wave and rolls over onto the step.
This usually takes two to five seconds, depending on
the loading and the water conditions. As the hull reaches the level
position on top of the water, the full force of the 160-hp Lycoming
is felt, and the pilot and passenger are pressed back in their seats
from the acceleration. With the stick in the neutral position, the
pilot hardly has time to enjoy the takeoff run before the plane is
lifting off the water. When landing the Glass Goose on water, the
pilot sets up with full flaps and makes his approach. Once in the
very strong ground effect afforded by the large bottom surface of
the plane, the speed is reduced to very nearly stall and the tail
contacts the water first. The hull settles onto the water, the
throttle is reduced to idle, and the flaps are retracted as the
plane rapidly loses speed and settles into the water. The spray
rails do a good job of deflecting the bow spray away from the
cockpit. Yes, Scott stuck with a project long after so many people
thought it was a lost cause, and turned what was an ugly-flying
duckling into what is now the Glass Goose--a beautiful, high-flying
swan.
