c) Flight specifications
WARNING:
The wing has not been designed for aerobatic flying.
Pitch attitudes limited to + or - 30°
•
Roll banking limited to 60°
•
No inverted flight
•
V.N.E. (velocity never exceed) : 81 mph (130 km/h)
•
Stalls authorized only in glide path with a progressive speed reduction and
•
throttle to idle position.
Over these limits, some stability problems, loss of control, structural failure or
irreversible "tumbling" motions can occur.
Better handling will only be reached after about 10 flying hours and roll control will be more difficult
during the first flights.

Control bar :
Pushing the control bar forward causes the wing to pitch nose up ,which increases the angle of attack (the
aircraft will climb) - primary effect, and a decrease in air speed- second effect.
Maneuvering the control bar laterally causes the trike to shift in the opposite direction of your movement, thus
changing the center of gravity of the aircraft. It produces a roll movement in the direction of the trike
displacement (control bar handed on the left, center of gravity moved on the right : .roll movement on the right)
−
Trim :
The neutral position of the trim corresponds to the alignment of the mobile nicopress stop in the control
window with the "O" of the scale. This setting is recommended for take-off and landing maneuvers. To
hand-off cruising speed
increase the
mark appears on top of the control window, facing the "rabbit". Do not try to turn above this position or the
control cable may turn in reverse direction. To decrease the cruise speed , turn the control knob clockwise. You
reach the minimum once mark appears on bottom of the control window, facing the "tortoise".
To counter ageing effects on the sail and the increase of the billow that decrease the trim efficiency, you can
move the sheath end on the A-frame strut upwards in order to tense the cable. Just unscrew the tightening nut,
choose your setting, place the nut back, and bring the exceeding piece of sheath into the empty part located
between the top of the A-frame strut and the king post. Keep the same value as this one to move the cable-
clamp set below the sheath stop upwards, in order to do not change the positioning of the mark within the
window.
−
Short take-off and landing techniques :
The minimum take-off roll distance is reached by increasing R.P.M. to full power with brake, and pushing the
control bar fully forward. The control bar should be brought backwards immediately once the wheels are in the
air to obtain a climbing speed ranging of 70 km/h ( mph) according to the load. A short landing needs a slow
approach speed ranging of 70 km/h ( mph) and raise the nose a few meters before touching the ground, in order
to touch the wheels at stalling speed. Brake and pull the control bar at its maximum in order to reach a better
aerodynamic braking once the rear wheels have touched ground.
