Control bar :

Pushing the bar forward causes the wing to pitch nose up ,which increases its angle of attack and increases its

speed.

Maneuvering the bar laterally causes the trike to shift in the opposite direction of your movement so as the

center of gravity of the aircraft. It provokes a pitch attitude in this direction (maneuvering the bar to the left :

center of gravity shifted to the right: pitch on right).

Short take-off and landing techniques :

The minimum take-off run distance is reached by pushing the nose up from the very start of the take-off run

and keep it thus, until the wheels are airborne. Maintain a speed of 45km/h to climb according to the best

climbing angle. A short landing needs a slow approach speed of about 50 km/h. Hold the wing level with the

ground until landing. If your trike is not equipped with brakes, pull the control bar to the utmost in order to get

better aerodynamic braking once the rear wheels have touched ground.

−

Behavior during stalling :

Stalling point will be easier reached on the rear trim position. You will feel that it is close when the control bar

starts pushing back forcefully. By simple allowing this downward tendency for a moment, the wing will return

to correct speed. In that case the loss of altitude will be less than 10 m. If the control bar stays pushed out in

spite of the warning signs, the wing will drop lower and the loss of altitude may easily reaches some 30 m. An

asymmetrical start in one wing is possible, particularly during the running-in of the sail (first 50 flying hours).

To avoid tumbling risk, the stalling exercises must be imperatively carried out throttle down engine, with a

slow and steady slackening speed obtained by a progressive control bar pushing out.

−

Behavior in strong wind :

When stationary on the ground

Park the aircraft perpendicularly to the direction of the wind, with its windward wing lowered. Block the

'A' frame on the front tube of the trike with the Velcro used for packing the sails and put a wedge under the

three wheels. Take the wing off the trike and put it flat on the ground windward, if the aircraft is not going

to be used immediately.

Ground runs

Keep the sail flat into headwind.

Push the control bar against the trike front strut by tailwind. This will avoid tipping over. Slightly lower

the windward wing with side wind. It may be difficult to hold the 'A' frame in its position. Never lift the

wind lift the wing up.

Take-off and landing

As ground run distances are considerably lessened by strong wind, try to place yourself into wind. Should

this not be possible, perform the take-off or landing maneuvers with greater speed than you normally do, in

order to reduce the drift angle and counter the effects of the gradient. Keep to the axis of the runway with

the front wheel control.
