and quickly at speed a little higher than the trim speed. As the glider begins to turn, you may push the bar
out a little for making the turn faster, and then move it back.
Don’t do this at low speed.
You must keep
the speed corresponding to the bank angle. Stalker Phantom is stable in multiple 360-degree turns in both
directions and has no sideslip.
4.5. Using RVG
RVG system is designed for increasing glide ratio at high speed. That system decrease the aileron set up
angle on 3deg. Therefore the pitch stability is decreased also and, as result, bar pressure becomes lower.
Trim speed with RVG ON becomes higher on 12-14km/h.
Climbing. RVG mode – OFF(rope is released). Excellent control at low speed, best possibility for
finding good climb. Too much bar pressure at high speed.
Gliding. RVG mode –ON (rope is pulled). Use that mode if you are going to fly for a long time at
speed higher than 75-80km/h. Glider has best glide ratio at high speed. Bar pressure do not make you tired
during long flight at high speed. That is quite difficult to climb with RVG ON due to high trim speed and
not that comfortable handling as with RVG OFF. Also in combination with backward CG position at low
speed the pitch stability can be not enough for climbing in turbulent conditions. So do not use that mode for
climbing.
4.5. Using flaps
The Stalker Phantom has flaps deflection range 0~55deg. After full flaps deflection trim speed is decreased
by 8~10 km/h and speedbar moves backward by 150 mm.
The 0 deg. flaps is the best glide ratio and min sink ratio configuration.
The 15-20 deg. flaps is the climbing configuration – glider has best control with good sink ratio
Big flaps deflection angles are not recommended for climbing due to substantial increase in sink speed and
decrease in glide ratio. These big angles can be used for landing and quick descent.
4.6. Landing
As the Stalker Phantom is a high performance glider, you should land only up the wind and avoid going
downhill. Stalker Phantom requires thorough handling during landing.
For landing it is recommended to use from half flap up to full flap configuration.
That is not allowed to do big flare up. In case of big flare there is high possibility to hit the ground with the
tip and damage the tip.
Keep the wings level, speed the glider up slightly and fly right down till the altitude is 0,5 - 0,8 m from the
ground to the speedbar. At this altitude decrease descent rate by pushing slightly on the control bar. When
you feel the glider unresponsive to the bar movement, quickly ease the bar out all the way before your feet
touch the ground. With a good sharp final thrust, the sudden increase in drag will slow the glider very
suddenly and you will land softly. In zero wind conditions you will make few steps to stop the glider.
REMEMBER. Do not ease the bar out with surplus speed! It leads to sudden flare up and falling. It is much
better not to move the bar out at all, than move it too early.
We
wish
you
soft
landing
!
