    JOJO WINGS – SONIC Picking The Right Canopy It is important for your safety and enjoyment that you match your canopy with your ability and weight. Jojowings canopies are built in several models that span a wide range of canopy surface area.

  • Page 9: A Note About Slope Soaring

    JOJO WINGS – SONIC A Note About Slope Soaring Parachutes were frequently used for slope soaring or paragliding in the past. While this is an acceptable use, it can be very dangerous. The following guidelines will reduce the danger: 1) Obtain competent instructor before atempting any slope soaring. Many countries have organization that certify instructors.

  • Page 10: Assembly

    (Performed at assembly and after every 50 jumps or 120 days, whichever comes first.) As mentioned above, your Sonic canopy must be inspected thoroughly before it is jumped the first time and periodically thereafter. This procedure is more thorough than the inspection which should be completed each time the parachute is packed.
  • Page 11 JOJO WINGS – SONIC Here is one recommended procedure for inspecting your SONIC main canopy. Consult the owners manual for your rig and other components for instructions on inspecting them. It’s best to inspect your canopy in a careful, systematic way. We recommend starting at the top of the canopy and working down to the risers.

  • Page 12: Pre-Packing Instructions

    In other words, it is difficult to pack a ram-air main canopy so it won’t open. We’re not saying other packing methods won’t work with your Sonic canopy. But the method shown here will probably help your canopy open more consistently.

  • Page 13: A Word About Help

    JOJO WINGS – SONIC A Word About Help When you’re learning to pack, never hesitate to ask a rigger or your instructor to help. They will show you tips that will make the process faster and easier. Be sure they refer to this manual, however, as they might not know our packing method.

  • Page 14: Note

    JOJO WINGS – SONIC Note Sonics are designed for a slow-to-medium speed opening when packed as described in the manual - with each side of the nose rolled four complete turns towards the center. Do not tuck the nose into the center cells. The new airfoil design causes the center cells to form a pocket that can hold the rolls there during opening.
  • Page 15 JOJO WINGS – SONIC Risers. Check the riser releases carefully. They must be installed and assembled properly. Be sure the release cables are inserted correctly in the white loops. Check the steering lines and toggles. Look for damage, loose knots and slipping toggles. (Serious injuries could result if an incorrectly attached toggle detaches from the steering line during the landing flare –...

  • Page 16: Packing Procedure

    JOJO WINGS – SONIC Packing Procedures Stretch your parachute system out on the ground with the rig laying with the containers facing up. (If someone were wearing your rig at this point, he would be lying face down with his head towards your canopy.) Pull the lines straight before setting the rig down.

  • Page 17: Slider Preparation

    JOJO WINGS – SONIC Slider preparation The slider is designed to slow the speed of the canopy opening and thereby reduce the dynamic impact. The slider is made of polyamide fabric. It has the shape of a rectangle in the corners of which the rings are inserted - the grommets.

  • Page 18: Folding The Canopy

    JOJO WINGS – SONIC Folding the Canopy- „Pro-pack“ 1) Crouch next to the risers and face your canopy. Slip the fingers of your left hand between each left-hand riser and between the left-hand steering line and the risers. Do the same with your right hand.
  • Page 19 JOJO WINGS – SONIC 3) If the lines look something like this, then a Obr.3 steering line or riser group passed around everything else. A steering line that passes around everything else will result in a malfunction that will almost surely require a breakaway.
  • Page 20 JOJO WINGS – SONIC Obr.5 5) The nose openings should be facing the rig and the tail should be farthest from the rig. If the reverse is true, double check to be sure the rig is container-side up (the back pad is on the ground). If the rig is...
  • Page 21 JOJO WINGS – SONIC Obr.7 Obr.8 Obr.9 7) Starting with the end cell nearest your legs, flake the entire nose with one hand as shown. 8) Pull each cell completely out, and keep it in your hand. 9) Then pick up the next, taking care not to miss any until all of them are in your hand.
  • Page 22 JOJO WINGS – SONIC 10 a 11) When you have the entire nose flaked, tuck it between your knees and hold it there. If your canopy is new, or it tends to open comfortably fast, then follow your steps 12 through 15.
  • Page 23 JOJO WINGS – SONIC Obr.15 Obr.16 15) Do the same on the other side. When you´re finished rolling the nose, it should look like the above illustration. Put the rolled nose between your legs and grip it with your knees to prevent it from unrolling during the rest of the packing procedure.
  • Page 24 JOJO WINGS – SONIC 19) Find the group of A lines on one side of the canopy. With the canopy Obr.19 Obr.20 held in front of you as you have it now, the A lines are the front part of the line...
  • Page 25 JOJO WINGS – SONIC 22) Now find the D line group, the group of lines nearest the tail. (Not the steering lines, they are attached at the trailing edge.) Pull the left-hand steering lines off to the left (to get them out of the way).
  • Page 26 JOJO WINGS – SONIC Obr.25 Obr.26 25) Now grasp the steering lines where they attach to the tail, pull the entire tail out and drop it straight down 26) Now organize the steering lines and tail so the canopy looks like this.
  • Page 27 JOJO WINGS – SONIC a line-over malfunction and canopy damage may result. Obr.29 Obr.30 Obr.31 29) Wrap that part of the tail half way around the canopy. Hold in place with your knees. Fold the tail on the other side of the canopy the same way.
  • Page 28 JOJO WINGS – SONIC Obr.34 Obr.35 35) Dress canopy to a width slightly wider than the width of the bag. All the slider should stay inside the rolled tail. The slider must not be allowed to move down the lines - even the smallest downward movement of the slider may increase opening shock and decrease reliability.
  • Page 29 JOJO WINGS – SONIC Obr.38 Obr.39 38) Now put one hand under the top of the bundle and make an S fold in the opposite direction as shown. The remaining material can be rolled under the fold. 39) You should now have a neat compact bundle.

  • Page 30: Cleaning Your Canopy

    JOJO WINGS – SONIC Cleaning Your Canopy Standard Materials Avoid washing or cleaning your canopy if at all possible. Cleaning the material will increase the porosity, causing reduced performance. Only clean areas that are contaminated with a substance that will degrade the material. Mild soap and water will remove most contaminants. If necessary, mineral spirits may be used for grease or oil.
