Design
The fuselage and vertical tail of the 3X55 is a one-piece structure made from fibreglass. The firewall is a Fiberfrax ceramic/aluminium sandwich.
The cockpit is 47.5 inches (1.21 m) wide at the elbows. Crew access is via a door on each side of the cockpit that hinges upwards and is supported by a gas strut.
The control sticks are located conventionally in front of each seat. The standard throttle arrangement is one panel-mounted centre throttle, but a second throttle located on the left side of the panel is optional, allowing the left-seat pilot to fly with either hand on the throttle or stick.
The wings are strut-braced with a single spar and are made from fibreglass and foam with a 15.5% CAGI.R3 airfoil. The wing has a span of 31 .5 feet and an area of 127.4 sq ft (11.84 m2), which gives it a wing loading of 9.5 lbs/sq ft at gross weight. The aircraft has removable wings, with single locking pins and quick-disconnect controls which can be easily hooked up and inspected from inside the cockpit.
The wings have conventional Frise ailerons and slotted flaps. The elevator and rudder are also conventional. Ailerons and elevator are controlled by dual centre-mounted sticks through push-pull tubes, while the rudder is controlled by cables. The rudder cables attach to the rudder by wrapping around the wide bottom diameter of the rudder itself. The pitot tube is mounted in the left-hand strut.
The flaps are operated by a ceiling-mounted flap handle with detents for 0, 15 and 30 degrees of deflection. The flaps are controlled directly with the handle attached to a flap centre-section behind the fuselage and the wing flaps plug into the flap centre-section. Flaps are normally set to 15 degrees for take-off and 30 degrees for landing.
The plane comes in one colour – white, but owners can add their own vinyl decals to finish the plane as desired.
