Here you see the plug-in landing gear used by the designer to operate this flying boat off of terra-firma. They are made from music wire and simply slide into
brass tube sockets built into the fuselage sides.
The engine is located in front of the wing with the fuel tank slung under the
wing and just aft of the firewall. The designer converted an industrial 30cc gas
engine to power his flying boat but a Zenoah G- 38 ( horizonhobby.com) or similar size engine will do just as well. The throttle servo is installed in the wing
foam, and then need to be covered with
fiberglass and resin. They bolt to plywood
mounting points in the lower wing.
The control linkage from the servos
(installed in the fuselage) to the elevators
and rudder are done with pull-pull cables
like the full-scale airplane. Plastic-covered
stranded fishing leader or Du-Bro
( dubro.com) and Sullivan (
sullivanproducts.com) control cables and hardware can
be used. The battery pack is located forward
toward the nose to adjust the CG balance
and can be accessed through the cockpit.
IN THE AIR
The prototype required some nose weight to
balance properly. The 16-ounce fuel tank is
located below the wing and behind the
engine. The first flight of the Aeromarine was
with a 16x6 prop but the power was just about
adequate. A switch to a 16x8 prop proved
much better with increased performance.
The Aeromarine is seen occasionally flying from our club field, and Larry says he’s
looking for a suitable body of water to fly
from within a reasonable distance. The aircraft performs in a scale manner, but being
an antique aircraft design, no aerobatics or
have been tried. The model is best flown
slow and low. Try some flybys and the interesting appearance of the Aeromarine
Tractor Sport Boat will add fun to anyone’s
day. That’s what fun flying is all about.
