SONIC OWNERS MANUAL INTRODUCTION Thank you for choosing your Moyes Sonic. You have made a wise choice as this intermediate glider epitomises all the qualities of safety, performance, and handling that is the Moyes tradition. The development of the Sonic is indicative of the dedication of the Moyes design team who strive to offer a range of high quality hang gliders for ALL pilots.
SONIC OWNERS MANUAL DESCRIPTION OF DESIGN The Moyes Sonic, crafted with double surface and internal floating crossbar, is a combination of state of the art design features and materials, and high quality manufacturing standards, resulting in a uniquely high performing yet easy to fly flex wing hang glider. The cut of the sail has been carefully crafted to determine a controlled twist distribution with a perfect match to the leading edge curve, giving flutter free performance throughout the speed range.

SONIC OWNERS MANUAL OPERATING LIMITATIONS The Sonic has been tested and found to comply with current U.S.H.G.M.A Airworthiness Requirements. These standards require static aerodynamic load testing: • with a positive 30° angle of attack at 65 mph; • with a negative 30° angle of attack at 46 mph; • with a negative 150° angle of attack at 32 mph; and, • Pitching moment tests at 20, 35 and 50 mph to display the gliders inherent positive pitch stability through a broad range of angles of attack.
SONIC 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.
SONIC OWNERS MANUAL ASSEMBLY PROCEDURES The following procedures have been tried and tested as the most efficient method of setup. Your dealer should demonstrate both set-up and appropriate pack-up procedures when you take delivery of your new Sonic. Please note that the glider can sustain serious damage if the correct procedures for both set-up and pack-up are not followed. Refer to diagram insert for clarification. 1.
SONIC OWNERS MANUAL ! CHECK Check that the bridle lines are not twisted or kinked. ! CHECK Check that the rear top wire is not through or around any of the bridle lines. The king post should now be firmly fixed in a vertical position. 7. Take the battens from their bag and lay the green-tipped battens behind the right wing, starting with the keel (longest) batten, out to #7 near the wing tip. (The right wing is on your right when facing forward with the glider as if to fly.
SONIC OWNERS MANUAL Move to the rear of the glider at the keel and pull back the double wire crossbar restrainer cable so the stainless steel shackle will clip into the Bailey Block at the rear of the keel. ! NOTE FLAT SET UP Move to the rear of the glider at the keel and pull back the double wire cross bar restrainer cable. Raise the keel 10” (250mm) off the ground so the stainless steel shackle will clip into the bailey block. 9. The tip (#7) battens can now be installed.
SONIC OWNERS MANUAL PRE-FLIGHT CHECK On the Sonic many of the assemblies and parts to check that are normally visible on beginner or intermediate-type gliders are concealed to reduce parasitic drag. It is still imperative that you have a complete and systematic checking procedure that is performed before every flight. It is best to start at the same place and follow the same routine, returning to the start point for every pre-flight.
SONIC OWNERS MANUAL 7. Release the bottom of the nose fairing and inspect the nose plate assembly: nuts, bolts, and top wire tangs and thimbles. Check Bailey Block for proper attachment of nose wires. Refasten nose fairing. 8. Sight along each leading edge checking that they have a similar curve. Any noticeable difference would indicate a bent leading edge that would cause a substantial “turn” in the glider’s trim. 9. Move out along the wings feeling for dents in the tube. 10.
SONIC OWNERS MANUAL DE-RIGGING THE SONIC Laying the Glider Flat If the wind is over 10 mph and you wish to park the glider safely, it is best to lay the glider flat on the ground with the nose into the wind. To do this, simply lift the nose fairing to expose the nose catch assembly.
SONIC OWNERS MANUAL 6. Unclip the king post and lay it forward. Clip the wire to the reinforced sail area around the king post base. Attach the reflex bridle clip to the same area. Don’t forget the padded cover for the top of the king post. 7. Slide the padded sleeve up the keel until it covers the tangs and fittings at the rear of the keel. Place a tie under the glider (around the middle) and lift the two sail halves by wrapping the Mylar pockets up toward each other.
SONIC OWNERS MANUAL 4. Remove remaining battens and pack them in the batten bag as per flat pack-up description. 5. Release reflex bridles and clip onto the sail at king post base. Undo top back wire and clip onto same place, allowing the king post to fold forward. Cover king post top with padded bag. 6. Walk in each wing making sure that the crossbars don’t jam between the leading edges. Pull the sail out and over the leading edges and fold them forward. 7.
SONIC OWNERS MANUAL FLYING THE MOYES SONIC Harness Adjustment In any glider it is important to have your harness and hang loop arrangement as simple and safe as possible, as well as being arranged to give the most comfortable and controllable position throughout the entire flight, from the start of your take-off run until your feet finally touch down at landing.
SONIC OWNERS MANUAL In windier conditions, hold the glider at the angle of attack that allows the wing to generate maximum lift without stalling or causing wing balance problems, but at the same time allows you to stand comfortably without being lifted or holding any glider weight. If wire assistance is available, have them hold the front and side wire, but ensure you have advised them of what you require and what your commands will be.
SONIC OWNERS MANUAL this tends to be a rather mellow reaction, and as the Sonic is highly spin resistant, control should be easily regained within 180 degrees of rotation. Pulling the bar in from trim position and increasing air speed requires very little effort and as is normal with most aircraft, with the increased air speed we get a faster lateral response of roll rate. It is here that the erratic/tense flier will discover control problems.
SONIC OWNERS MANUAL If you have been flying lower-performing beginner type gliders, then the extra glide and ground effect of the Sonic must be allowed for in the planning of the approach. Secondly, always fly your approach with moderate speed, even through turbulence so that no excessive yawing can develop. Nothing spoils a landing approach like a glider that keeps pointing off course.
SONIC OWNERS MANUAL GENERAL TUNING HINTS As your new Sonic is test flown prior to delivery, you can have reasonable confidence that unless it has been damaged in transport it will arrive with standard factory trim. This setting is achieved when the sum of the dynamic air pressures of the aerofoil (centre of pressure) are centred in the same position on the glider as the sum of the gravitational forces (centre of gravity).
SONIC OWNERS MANUAL Bent or Damaged Leading Edge: Remove the leading edges (start with the one on the side to which the glider seems to turn) and check them for bends or dings. If you can not find a bend, one of them may have been stressed and as a result, now displays a slightly different flexing characteristic to the other. (You will find directions for sail removal and leading edge removal in the Maintenance section.) If the leading edge is bent beyond straightening (ie.
SONIC OWNERS MANUAL Trim Speed Trim speed adjustment can be achieved by moving the hang loops forward to increase trim speed or aft to bring the speed closer to stall. Once again, never move the loops more than 1/2” at a time, ensuring that they are secured in their new position. At any stage it is unlikely that adjustment beyond an inch or two is ever necessary. Should you feel that greater adjustment is required than please ask your dealer to retest the glider.
SONIC OWNERS MANUAL GLIDER CARE The modern hang glider requires very little in the way of maintenance, especially if you take a little extra care with your day to day use and treatment. Storage Keep the glider in its bag and store in a cool, dry place. It is best if the glider is stored on some suitably padded racks where the air can circulate. Avoid leaving the glider on the floor or ground for any length of time as this allows ground moisture and small creatures to work their way into the sail.
SONIC OWNERS MANUAL Take care with the battens and avoid unnecessary damage by packing them in the correct manner. If reshaping is required, avoid over working the tube as this will soften the alloy causing the batten to lose shape more easily. Take care when removing the battens. If you are packing up using the “on-frame” method, don’t allow the fibreglass end to get caught on the ground behind you.
SONIC OWNERS MANUAL The hardware fittings are often the cause of sail and tube wear if they are not padded correctly. The plastic components are tough and carry very little load, but once again, unusual impacts may cause stress fractures. It is therefore important to be aware of their condition. Avoid over-tightening nuts. Junctions should be free to swivel, especially rigging tangs and terminations. Transportation Always have sufficient padding between the glider and supports.
SONIC OWNERS MANUAL MAINTENANCE SCHEDULE Apart from your normal pre-flight checks, and even if you have conscientiously maintained the glider in A1 condition, more thorough checks of the glider are necessary from time to time. If you follow the schedule faithfully, you will not only extend the possible life of the glider, but give yourself many more hours of anxiety-free flying. Every 10 hours: • Check top and bottom surface battens against template.
SONIC OWNERS MANUAL CHECKING THE SONIC STABILITY SYSTEM Use No. 8 Plaited Nylon Bricklayers Line to check the luff lines of your glider, this is done by using a string with a loop on each end, place one end of the string over the batten, below the luff line which is being measured. Attach the other end of the string tightly over the batten of the same luff line in the opposite wing. Measure the height of the string above the keel to the proper height. Use the same method to measure the second luff line.
