  • Page 5: Introduction

    The Litespeed incorporates the latest high performance hang gliding design technology. Since 1967, Moyes Delta Gliders has strived to be on the cutting edge of developing hang gliders of the highest calibre. A family owned business operating under homespun values, we aim to provide a comprehensive international network to service all pilots.

  • Page 6: Description Of Design

    The stability system was designed with maximum strength and stiffness in mind, and demonstrates excellent structural integrity under any flight load. The Litespeed sail has a total of 8 internal cloth ribs. These internal ribs restrict the under surface from ‘blowing out’ which prevents pilot induced oscillations. The internal ribs are cut to a specific airfoil, which produces the desired under surface camber for low drag high speed gliding.

  • Page 8: Operating Limitations

    The Moyes Litespeed is capable of easily flying at speeds greater than the VA and VNE. We recommend you use an accurate airspeed indicator and familiarise yourself with control bar positions at these speeds and normal flying speeds.

  • Page 9: Disclaimer

    LITESPEED OWNERS MANUAL DISCLAIMER The owner and operator must understand that due to the inherent risk involved in flying such a unique vehicle, no warranty is made or implied of any kind against accidents, bodily injury or death. Operations such as aerobatic manoeuvres or erratic pilot technique may ultimately produce equipment failure, and are specifically excluded from the warranty.

  • Page 10: Getting Started

    LITESPEED OWNERS MANUAL GETTING STARTED Your new Moyes Litespeed may have been shipped to you in the 4.5 metre breakdown form. If so, you can assemble your glider to its full length by following the assembly procedures. All references to ‘top’ & ‘bottom’ and ‘left’ and ‘right’ are referred to with the glider in flying mode.
  • Page 11 LITESPEED OWNERS MANUAL 3. Insert the right hand back section of leading edge. The right hand back section differs from the left in the mounting of the outer sprog. You can check this by picturing that the cable must be on the top side of the leading edge and the sprog must fold inboard.
  • Page 12 5. Repeat steps 1-4 to install the left hand back section of leading edge. Your Litespeed will now be ready for the standard assembly. Before flight, make a thorough inspection of all tubing and nuts and bolts to ensure no damage has occurred during transportation.

  • Page 13: Assembly Procedures

    1. Place the glider on the ground, zipper up. Open the bag, undo ties, remove A-frame bottom padding and battens. NOTE Take special care with the wires, the Litespeed features 1x19 cable which can easily be kinked unless special care is taken. 2. Assembly the A-Frame.
  • Page 14 LITESPEED OWNERS MANUAL 4. Insert the ring of the lower front wires in the Bailey Block making sure that the spring is firmly locked and the wires untwisted. Picture 8 Attaching the front wires to the Baileys Block. 5. Insert the nose batten. The batten may need some “feeding” through the Sail by pulling the sail forward to remove any wrinkles as the batten slides into its pocket.
  • Page 15 Picture 11 Tension the glider. 8. The Litespeed is equipped with a removable keel aft section. The glider can be left resting on it, facilitating the fitment of the washout struts, and battens. If desired, the glider may now be raised onto its keel to complete the assembly. This also assists with keeping the sail clean by keeping the tips off the ground.
  • Page 16 9. Insert battens gently from the root towards the mid span, battens 1-6 only for the Litespeed 4 & 5, battens 1-5 only for the Litespeed 3. Use only gentle pressure when inserting the battens, this will greatly extend the longevity of the batten pockets.
  • Page 17 LITESPEED OWNERS MANUAL 12. Insert the remaining mainsail battens, 7 to 11 on the Litespeed 4 & 5 and 6 to 10 on the Litespeed 3. 13. The battens have been adjusted in the factory, but may need to be readjusted upon initial assembly.

  • Page 18: Pre-Flight Check

    If your harness height from base bar needs adjustment, it is best to acquire the correct length loop from your Moyes dealer. 2. Move up to the suspension system and verify that the dingle-dangle is rotated perpendicular to the keel and is free from the nose batten pocket.
  • Page 19 LITESPEED OWNERS MANUAL 8. Move out along the wing looking and feeling for any damage. Open the zip where the side wires enter the sail and check that bottom wires are not kinked, twisted or damaged. Check the cross-bar/leading edge junction bolts and nuts and check that the ball joint is not bent.

  • Page 20: De-Rigging The Litespeed

    LITESPEED OWNERS MANUAL DE-RIGGING THE LITESPEED Disassembly of the Litespeed is virtually an exact reversal of the set-up procedure, however, a few important points must be remembered to avoid unnecessary damage. 1. If desired, the Litespeed can be disassembled on its keel.
  • Page 21 LITESPEED OWNERS MANUAL Folding the Sail Tips - METHOD 2 • Begin to roll the sail tip around the leading edge. • Continue to roll the sail until tightly rolled around leading edge. • Fit the sail and the outer dive strut into the boot.
  • Page 22 LITESPEED OWNERS MANUAL 7. Fit rear keel protector piece over bailey block assembly. Picture 20 Fitting the keel protector piece. 8. Fold and roll the sail parallel with the trailing edge. Picture 21 Rolling the sail. 9. Attach ties loosely around glider, going from wing tip to nose, and then tighten the ties, moving from nose to wing tip, adjusting the sail so that the leading edge Mylar inserts overlap smoothly with no kinks, as shown.
  • Page 23 IMPORTANT Special care must be taken with cables. The Litespeed features 1x19 cable for increased strength and low drag, but this cable is very easily kinked unless special care is taken.

  • Page 24: Flying The Moyes Litespeed

    In some situations it is recommended to launch the glider with 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 never to use more than 1/3 VG, as the glider will become very difficult to control if turbulence is encountered during or just after take off.
  • Page 25 It is possible to thermal the Litespeed with up to 1/3 VG and experience a noticeable gain in sink rate by doing this. However, when the VG is pulled 1/3 tight the Litespeed needs more significant high siding, especially at low bank angles. Handling is also quickly lost if the VG is pulled any tighter.
  • Page 26 With full VG, the Litespeed sail has far more tension than on previous Moyes gliders. The Litespeed is intended to be tuneable for all situations, and with VG full tight the glider becomes quite difficult to control. The full tight VG setting is only intended for high-speed glides, and especially high-speed diving into goal.
  • Page 27 If rain is encountered while flying your Litespeed, keep airspeed well above stall, especially near the ground. If the wing stalls you may need a significant pull in of the bar to lower the angle of attack enough to restore normal airflow.

  • Page 28: Tuning Hints

    LITESPEED OWNERS MANUAL TUNING HINTS The staff at Moyes are more than willing to provide advice or help in the tunning of your glider. Feel free to contact Moyes at: T: +61 (0)2 9316-6466 F: +61 (0)2 9316-8488 E: moyes@moyes.com.au Trim Adjustment Upon delivery, your Litespeed should have been test flown by a factory test pilot.
  • Page 29 If your glider falls into one turn direction more than the other you have a spiral turn. If you check carefully you will notice that your glider will also have a gentle turn with the VG off in straight flight. With the Litespeed, this kind of turn becomes more noticeable with VG 1/3 on.

  • Page 30: Performance Tuning

    Simply: DO NOT LOWER YOUR DIVE STICKS. Eccentric ring adjustment. The Litespeed has a series of eccentric rings along the length of the leading edge tubes which can be rotated to change the characteristics of the glider. Essentially, two sets of these rings can be used for fine tuning.
  • Page 31 LITESPEED OWNERS MANUAL How to Adjust the Eccentric Rings. The mid section ring can be adjusted freely with no consequence to safety of the glider. Do not rotate these rings beyond 45 degrees; any more rotation is unnecessary and will not provide any advantage.

  • Page 32: Glider Care

    LITESPEED OWNERS MANUAL GLIDER CARE Your Moyes Litespeed will require very little in the way of maintenance if you take a little extra time and care with your day to day treatment and use. Storage Keep the glider in its bag in a cool dry place. Store the glider off the floor or ground and free from contact with oils, solvents or acidic substances.
  • Page 33 Moyes Dealer. Special Note to Coastal Fliers The Litespeed uses thin wall 7075 tubing throughout the airframe, which is considerably more vulnerable to corrosion than the 6061 alloy used on previous gliders. The 7075 suffers corrosion for two reasons.

  • Page 34: Maintenance Schedule

    Damage in higher stress areas such as the trailing edge or centre seam need to be fixed by a professional sail maker. It is always best to consult your local dealer or consult Moyes directly about repair of sail damage.

  • Page 35: Sail Removal

    We strongly suggest that you do not attempt this if you are not familiar with this glider. We recommend that you take the glider to your nearest Moyes dealer for such procedure. 1. Lay the glider flat on the ground and unzip the glider bag, roll glider so that it is top-side up, remove all the ties, and spread the wings a few feet.

  • Page 36: List Of Fasteners & Airframe Bolts

    LITESPEED OWNERS MANUAL LIST OF FASTENERS & AIRFRAME BOLTS It is very important not to over tighten your airframe bolts. All airframe bolts should be tightened just enough to take up the slack. All bolts should show 1 1/2 threads exposed above the nyloc nut.

  • Page 37: Checking The Litespeed Stability System

    LITESPEED OWNERS MANUAL CHECKING THE LITESPEED STABILITY SYSTEM Checking the stability system of the glider consists of measuring the height of the trailing edge over (or below) the keel. The glider must be supported so that the side wires are tight. This can be achieved more easily when the VG is full tight.
  • Page 38 LITESPEED OWNERS MANUAL IMPORTANT All measures are taken from the top of the keel, if string line falls below the keel, measure from bottom of keel and add the diameter of the keel (42mm or 50mm). 2000 MODEL LITESPEEDS Batten Numbers...
