CG ADJUSTMENT
CG adjustment is done by changing the location of the hang point along the keel. The farther
forward your hang point is, the faster the wing will trim, the less effort will be required to fly fast,
and the more effort will be required to fly slow.
On Sting Ray the hang point position is adjusted by trim device, repositioning the hang block along
the keel tube in flight and on the ground.
10. MAINTENANCE
This section contains a recommended schedule of periodic maintenance. None of the items in this
section are a substitute for the continual and consistent practice of proper pre-flight inspections
and immediate maintenance of any items on the wing, which require it. Safety requires that your
wing be fully airworthy for every flight. Nuts and bolts must always be secure, safety rings must
always be in place, and damage to any part, which could compromise the airworthiness of the
wing, cannot be tolerated. If you have a question about the need to repair or replace some part of
your wing, feel free to contact your dealer or Aeros directly. It is not always obvious which item
may require attention and which may not. Minor dents or dings in a non-critical location on the
airframe tube may not require any repair or maintenance. On the other hand, a wire that has been
kinked one time can fail very quickly after that, and should be replaced immediately.
We recommend that you have all maintenance work done by your Aeros dealer.
EVERY SIX MONTHS
1. Check the sail washout as described in the SPROG MEASUREMENT section.
2. Check all battens on a flat level floor against the batten diagram provided, and correct any that
deviate from the pattern by more than 5 mm (1/5").
3. Have a complete inspection performed on the wing and replace any suspension system
component that shows any wear and any cable that shows any kinks, wear, damage, corrosion,
etc.
4. Inspect all bolts for tightness, all safety rings for proper installation and possible damage.
Inspect plates and fittings for damage, holes in tubes for elongation.
5. Inspect the sail for wear, tears, UV damage, loose stitching, etc.
6. Lightly spray all zippers on the wing with silicone spray lubricant. Also spray your battens before
you install them in the wing to lubricate the insides of the batten pockets. Do not use any other type
of lubricant. Wipe off any excess silicone so that it does not attract dirt.
7. Inspect the inboard and outboard sprogs and sprog cables for possible damage.
EVERY YEAR
In addition to the normal six month service items, also perform the following:
1. Have the sail completely removed from the frame and disassemble all frame components.
Inspect every part of the wing for any damage or wear. Inspect the tubes for straightness and for
signs of corrosion.
2. Anytime you have the sail off the frame, inspect all of the batten pockets and batten pocket
stops.
3. Replace the hang block heart bolt.
