Use your body as a “torsion spring”: Draw the model from behind of your back. Unwind before the launch and in
the last launch phase twist the body and move your arm.
Move the CG and trim the elevator, so that the model climbs mildly. Play also with the CG position so that the
amount of the inherent stability suits your flying style: these models fly at low heights and often must cope with lots
of turbulent air. Larger amount of longitudinal stability provided by more forward CG position can be of advantage.
The wing flaps are in neutral position for launch and fast flights while hunting for thermals and for rapid returns
from downwind distances.
The ”neutral position” is with flat wing surface bottom.
For the low sinking rate deploy the flaps about 3 mm down (measured in the wing centre). Deploy the flaps about
40 deg down for escape from height and landing. The directional control with fully deployed flaps should be done
with rudder rather than with ailerons. The model with flaps full down slows down. When moved rapidly back to the
neutral position, the model can stall because the velocity is too low for the wing in this configuration.
Important notes:
•
NEVER launch model
if there are persons
in front of you!!! Remember, the velocity of the model can be close
to 150 km/hour
•
If released too early, the model can fly low over the ground, to the right side (right hander). BE ALWAYS SURE
there are no persons in this segment!!!
•
Secure the receiver crystal in place with adhesive tape. Otherwise, it can slip out of the socket due the launch
acceleration!!!
•
Do not launch model in weeds taller than about knee-height. You would easily damage the outer wing tip.
•
Before the first flying, make the test range of the RC set. The carbon used for the fuselage can influence the
signal reception. If you do not have the 2,4 GHz set, the “old fashioned” antenna between receiver and fin tip
still works best.
