SONIC OWNERS MANUAL

24 Version 1.01

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. This

causes some pilots to think the batten is stuck and the resulting extra force snaps the

fibreglass end.

The tip batten should never be lifted when being removed as the plastic tip may jam in

its cup and be snapped.

Rigging Wires

At the first sign of any fraying or kinks you should replace the wire immediately. Keep a

constant eye for damage to the outer plastic coating or any discolouration as these are a

sign that damage may exist either from an external force or from corrosion.

If the thimble has been elongated, then the cable, thimble and nico-press have been

exposed to a force of over 300-400 lbs. Once again, replacement of the wire is advised.

If you frequently set-up or break-down on rocky ground, you will need to inspect and

replace your cables more often.

If by some chance your wires are immersed in salt water, it is advisable to at least

replace your bottom side wires. Wires are not expensive but do play a rather major role

in holding the glider together.

Tubing

Once again, contact with salt air and water are a major concern and removal of the tube

end caps will be required to thoroughly flush out with fresh water. Corrosion and

electrolysis set up amazingly fast; follow your maintenance schedule conscientiously.

If wear marks or scratches begin to appear on any tubing, carefully investigate your

pack-up procedure and pad the areas showing wear.

Following any hard landing, check the impact areas for dents and bends. Opening the

sail upside-down and inspection inside the double surface will probably be required.

Hardware

All the Sonic hardware is of aircraft quality and stainless steel. However, there is no

such thing as an indestructible material, so regularly check for bent bolts, especially

following harder than normal landings or impacts.

Ensure that thread is exposed above all locknuts.
