with nose down parking. To fill the tanks to the full 50 gallon
capacity, the nose wheel must be extended to level the aircraft.
Be careful to hold the nose down during this operation. The nose
can be lowered after full up fueling with the caps on without
leaking. However, heat expansion may force fuel out the vents.
Filling to the full capacity should be done only when required low
gross weight, extended-range trips.
CAUTION
Fuel additives should be checked for compatibility prior to use.
Some fuel additives such as MEK, and deicing fluids like
"Canned Heat", and auto gas (especially the high aromatic
content, no-lead) should NEVER be used. Even extremely small
amounts of dissolved epoxy can gum up and plug the carburetor.
CONTROL SYSTEM
Pitch is controlled by a full-span canard slotted flap providing a
large allowable c.g. range. Roll is controlled by conventional
ailerons on the rear wing. The cockpit controls are similar to
most aircraft with pitch and roll controlled by the side sticks and
rudder pedals for yaw. The side stick controllers are employed to
give the pilot the smallest workload control arrangement
possible. The rudders, located on the winglets at the wing tips,
operate outboard only, providing two totally independent
systems. The rudders are used singly for yaw control or can be
deployed together as a mild speed brake.
BRAKES
Brakes are provided on the main wheels. They are used
together for deceleration on the ground and individually for
directional control at low speed on the ground. The brake
actuating mechanism is the rudder pedal; after full rudder
deflection is reached, the brakes are actuated. The brake master
cylinder is the rudder stop. This system aids in keeping brake
maintenance low by insuring that full aerodynamic control or
braking is employed before wheel brakes are applied.
The parking brake is provided by the rubber bumper on the nose
gear (nose down parking). For those aircraft not equipped with a
starter there is a brief period, after the engine is hand prop
started, while the pilot enters the cockpit that the aircraft could
roll forward before he can get his feet on the brakes, unless, of
course, the passenger has already boarded, in which case the
front seat passenger can hold the brakes while the pilot boards.
