FLYING THE MOYES LITESPEED
Take-off
The Moy es Litespeed has slight tail heavy static balance and therefore is v ery easy to
launch in calm or windy conditions, and on steep or shallow slopes. The nose should be
held slightly above horizontal with the wings level. Your run should be a smooth acceleration
w ith appropriate pitch control for the situation, and once a safe ex cess of minimum air
speed is acquired, a slight easing out of the bar will giv e a smooth lift-off. In w inds in
excess of 10-15 mph (16-24 kph), some wire assistance may be required.
Using the VG for Take-Off
In some situations it is recommended to launch the glider w ith up to 1/3 VG. It should be
noted that the Litespeed has an enormous VG range, and 1/4 VG is equivalent to VG
loose on many other gliders. It is important nev er to use more than 1/3 VG, as the glider
will become v ery difficult to control if turbulence is encountered during or just after take off.
In w indy conditions, some VG can help the glider penetrate forw ard aw ay from the take-
off and aw ay from any danger. With 1/3 VG the glider has a more solid feel and it
becomes more difficult to ov er-control or produce pilot induced oscillations. On the other
hand, many ex perienced pilots prefer to fully open the VG during w indy or turbulent
take-offs to allow for maximum control. For y our first w indy take-off on the Litespeed it is
recommended to use 1/4 VG.
For light w ind or nil w ind take-offs some VG can help the glider lift sooner making
take-off easier. This is especially helpful for take-offs on shallow slopes as the gliders
increased performance w ill allow for a shorter take-off run. Its important to note how ev er
that w ith more VG, the glider becomes more prone to tip stalling, so if VG is used during
take-off special care must be taken to keep the wings v ery level.
For cross wind take-offs a hang glider becomes much more vulnerable to tip stalling, so
usually its best to launch with the VG fully opened in these situations.
Litespeed Variable Geometry
The Litespeed features a v ery large VG range w ith a sail and frame construction that
makes this VG ex tremely pow erful and effectiv e. The initial pull of the VG has the most
significant effect on the sail tension. When VG is half on, much of the w ashout has
already been taken out of the w ing and w ith 1/2 to 3/4 VG the sail is already beginning to
rest on the div e struts in normal flight. The remaining 1/2 to 1/4 of the VG trav el begins
to take the w ashout out of the root and mid span. The ex tra sail tension has the effect of
flattening the battens slightly and producing a better high speed airfoil. The VG system
also operates the inboard div e strut compensator system allow ing for increased pitch
stability and safety margin when the VG is not full tight. The Litespeed features a similar
enclosed VG system to recent Moy es gliders, only w ith the addition of complete bearing
pulleys featuring a double pulley assembly on the keel and a second double pulley
assembly mounted inside one upright. The pulley assembly in the upright features
miniature needle bearings w hile the pulley s on the keel are conv entional rolling ball
bearings. This system of bearings makes the VG v ery easy to operate allow ing the pilot
to fine tune the w ing w ith minimum effort.
