DESCRIPTION OF DESIGN

Designed by elite competition pilots, the M oyes Litesport is intend ed for competitio n and
enjoyable high performance cross countr y flying. The Lite sport utilises a planform sim ilar
to the Litespeed.

The Litesport features a 7075T6 aluminium airfra me, which allows a co nsider able weight
saving over more conventional alloys. The leading edge uses a step down taper design
with revised sleeving and tube diameters. This produces a lighter outer leading edge
with an improved flex distribution. The low roll in ertia provides pleasant handling.

The elliptical fibreglass wing tip has been a feature of Moyes high performance gl iders
since the early 80’s. The fibreglass tip creates better turn coordination compared to
conventional designs. With the VG fully engaged, t he fibreglass tip produces a tighter
mainsail and more desirable washout distribut ion.

The pitch stability system utilises a cable braced outer aluminium sprog, providing
support for battens 8 and 9 via a transversal batten. This system was designed with
maximum strength and stiffness in mind, and demonstrates excell ent structural integrity
under any flight load. In addition, the k ingpost incorporates the G-string compensation
system, which lowers the rear of the sail when the VG is engaged. This allows the luff
line to adjust to the decrease in washout produced by the VG system.

The Litesport sail has a total of 8 internal cloth ribs. These ribs prevent the under
surface from ‘blowing down’, which makes pilot i nduced oscillations less likely. These
internal ribs are shaped to produce th e desired under surface camber for low drag at
high speeds.

OPERATING LIMITATIONS

Your Moyes Litesport is a sophisticated high performance hang glider. If maintained
correctly it will give you years of safe enjoyable so arin g. Howev er, it is im porta nt that you
display a healthy respect for all aspects of aviation and that you understand the
increased risks of flying in danger ous c onditio ns or in a m anner that exc eeds t he gli der’ s
operating limitations.

• Flight operation should be limited to no n-aerobatic manoeuvres where the glider’s
attitude does not exceed 30 degrees above or belo w the horizon and bank angles
do not exceed 60 degrees.

• The Moyes Litesport has been designed for foot launched soaring flight and should
not be flown by more than one person at a t i me. It sh oul d not be fl ow n bac kwar ds o r
inverted.

• The recommended minimum pilot skill level is Intermediate.

• The Moyes Litesport can be flown with a uxiliary power when fitted accord ing to the

recommendations of the manufacturer. The user assumes all liabilities.

• The Moyes Litesport should not be flown in excess of the placarded VNE or VA.

• VNE (speed never to exceed): 53mph / 85kph

• VA (maximum rough air manoeuvring speed): 46mph / 74kph

• Stall speed with maximum pilot weight: Less than 25mph / 40kph

• Maximum speed with minimum pilot weight: Less than 50mph / 80kph

The Moyes Litesport will resist spinning and will recover quickly if control forces are
relaxed. Recovery from a stalled turn ca n be achieved with little height loss and without
much attitude change if the control bar is brought back to a normal flying po sition. This
will allow the glider to return to normal flight within half a turn.

The Moyes Litesport has been tested to the following:

• Maximum lift angle of attack at a speed of 65mph/105k ph

• Negative 30 degrees angle of attack at a speed of 46mph/74kph

• Negative 150 degrees angle of attack at a speed of 32mph/54kph

• Pitch moment tests at 20/32, 37/59 and 54/87 (mph/kph)

These tests confirmed the glider’s structural integrity and positive pitch stability
throughout a broad range of angles of attack.

The Moyes Litesport is capable of flying at speeds gr eater than the VA and VNE. We
recommend the use of an accurat e airs p eed i ndic ator to beco me fam ili ar with co ntr ol bar
positions at these speeds and normal flying speeds.

GETTING STARTED

Your new Moyes Litesport may have been shipped to you in the 4.5m breakdown form.
If so, you can assemble your glider to its full length by following these assembly
procedures. All references to ‘top’, ‘bottom’, ‘left’, and ‘right’ refer to the glider and pilot
in flying mode.

Please check your packing list.

• Glider

• 2 x back section leading edges: note that the back s ections are labelled left and

right.

• 1 x batten set: red = left/ green = right/ blue = undersurface

• 1 x speed bar

• 2 x tip bags

• 4 x padding pieces: A-frame top & bottom, keel sleeve, king post top

• 1 x Snack Pack with owners’ manual, batten pattern, a nd promotional wear.

Assembly from 4.5m Breakdown Form

1. Open the glider bag and roll the glider onto its undersurface. Undo the straps and
extend the sail.

Picture 1

Lay the glider on
its undersurface
and unfold the sail.

2. Expose the leading edge/cross bar junction through the inspection zipper. Remove
the bubble wrap and tape from the leading edge/cross bar junction and the end of
the middle sleeve.

LITESPORT OWNERS MANUAL

Version 1.01 9

3. Insert the right back section of the leading edge. The left and right back sections
differ from each other in the mounting of the outer sprog. You can check this by
picturing that the cable must be on the top of the leading edge and the sprog must
fold outwards. Push the back section into the mid sleeve while depressing the push
button pin. Continue to slide the back section in until it reaches its stop, then rotate
the back section until the mid sleeve location hol es align with the push button pin.
Closely check that the push button pin has fully release d a nd that the back section
cannot be rotated.

ends of the leading
edge.

4. Secure the sail by attaching the tip webbin g to the end of the leading edge, using
the clevis pin and safety ring supplied. Insert the pin through the webbing and into
the bottom hole at an angle. Straighten the clev is pin while sliding the webbing
towards the leading edge as shown in P icture 3. Ensure the tip webbing is not
twisted and is on the bottom of the leading edge.

Picture 3

Insert the sail pin
Into the end of the
leading edge.

5. Repeat 1-4 to install the left back section. Your Litesport wil l now be ready for
standard assembly. Before each flight, carefully inspect all tubing, nuts, and bolts, to
ensure no damage has occurred during transportation.

The outer sprog must exit the sail from the long cord wise zipper. The zipper
must be opened when the glider is in standard break down form with the
sprog folding towards the wing tip.

7. Carefully spread each wing, making sure that you do not raise them above the level
of the keel. Ensure that the king post rises straight up. This preve nts the twisting of
the keel mount channel bracket.

Picture 8

Spread the wings carefully.

8. To tension the crossbar, pull the cord coming out of the keel pocket. Check that the
cable and rope are not twisted and that the shackle is secured within the Bailey
Block. Attach the king post rear wire behind the shackle, in the Bailey Block. In
strong winds the glider can be difficult to tension. Have a helper gently raise and
pull forward one wing.

Picture 9

Tension the Glider.

Check bottom wires are not twisted or kinked.

NOTE

!

DO NOT USE EXCESSIVE FORCE WHEN TENSIONING THE GLIDER.

If excess force is encountered check:

! The side wires are not twisted or kinked
! The cross bar retainer wire is not caught on the nose plate assembly
! The pull back wire or VG pulleys are not caught in the hang loop assembly

9. The Litesport is equipped with a rem ovable keel aft section. The glider can be left
resting on it, facilitating the fitment of the washout strut and battens. If desired, the
glider may now be raised onto its keel to complete the assem bly. This also assists
with keeping the sail clean by keeping the tips off the ground.

Picture 10

Raising the glider onto the keel can m ake
assembly easier and keeps the sail clean.

10. Gently insert battens 1- 6, moving from the centre of the wing towards the mid span.
Use light force when inserting the battens, as this will greatly extend the longevity of
the batten pockets. Red tipped battens are for the left wing, green for the right, and
blue for the under surface.

11. Open the zipper at the tip of the sail. Slide the fibreglass rod through the end of the
sail and into the end of the leading edge. Ensure that the rod is pushed hard against
its stop.

Picture 11
