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.
