FLYING SPEED
Indicated trim speed is dependent on the amount of brake the pilot is using, wing loading, altitude above sea level and the accuracy and
make of speed probe. The speeds recorded in technical data were at optimum wing loading at sea level using a Flytec 6030 thus there
could be a slight variation in speed range numbers that pilots records.
Speed readings in the flight reports could differ as this was measured during testing using various instruments and is an indication of
the difference between trim, stall and top speed. The speed range will be the same but the actual numbers may differ.
• With 0% brake and trimmers at 0 (Neutral) the HYBRID TANDEM will fly at 36-40 km/h with a sink rate of ~1.4m/s.
• Trim closed, and 25% brake the glider will fly at 30-34km/h with minimum sink rate 1.2 m/s.
• The best glide angle is achieved with closed trims and 0% brakes.
• At 80% of the brake range, the glider will fly at about 25km/h and will be close to the stall point at about 24km/h (at optimum weight).
THERMAL FLYING
HYBRID TANDEM has high internal pressure and needs very little pilot input even in very turbulent conditions.
In light lift it is advised to make flat turns to keep the glider from banking too much and avoid increasing the sink rate.
In strong lift conditions it is most effective to make small turns in the core with relatively high bank.
For the best climb rate in ridge lift we recommend using about 15% to 20% brake and
trimmers fully closed.
ASYMMETRIC COLLAPSE
If one side of the glider partially folds or collapses it is important to keep your flying direction by applying weight shift and some brake on
the opposite side of the collapse to counter any tendancy to turn towards the collapsed side.
CAUTION:
APART FROM WHEN FLARING AT LANDING THERE SHOULD BE NO REASON TO FLY WITH 70% TO 100% BRAKE. THE
SINK RATE OF THE GLIDER WILL BE EXCESSIVE AND THERE WILL BE A POSSIBILITY OF ENTERING A DEEP STALL OR
FULL STALL SITUATION. THERE IS ALSO THE RISK OF GOING NEGATIVE OR ENTERING A SPIN WHEN ATTEMPTING TO
TURN THE GLIDER NEAR THE STALL SPEED.
WARNING:
The use of the trim system in turbulent conditions or close to the ground is dangerous. While flying with the trims open, the glider has
a reduced angle of attack and is therefore more susceptible to turbulence and may collapse or partially deflate. Gliders react faster
when accelerated and may turn more. The trims should be closed in turbulent conditions.
