near the root. As you feed the frame slowly into the sail don't forget to insert the keel into the keel pocket of the sail.
Check periodically to see that none of the hardware is snagging on the sail or internal sail ribs.
7. Make sure you untie all sprogs from the leading edges and get them out of the sail through the sprog access
zippers.
8. Continue to slide the frame into the sail until you will be able to get the nose of the frame out trough the nose hole
of the sail.
9. Mount the sail mount webbing straps on the plastic caps of the rear leading edge tubes and secure them with the
sail mount webbing velcro. (See the section at the beginning of the manual about re-assembly after shipping.)
10. Attach the keel retainer webbing strap to the keel tube with the screw.
11. Attach the hang point tower with the spreader bar and a hang loop to the keel tube. Check that the routing of the
sweep wire and all VG ropes around the spreader bar is right and clear.
12. Insert the side wires through the side wires holes out of the sail. Mount the side wires to the corresponding
downtube fittings, making sure that no cable is wrapped around a leading edge or crossbar, and that no thimbles are
cocked or twisted.
13. Attach the rear wires to the rear of the keel.
14. Set the glider up onto the control bar.
15. Spread the wings slowly and carefully, making sure that the sail rides forward as necessary at the nose without
catching.
Be careful: you can easily tear the sail open at the nose.
NOTE
When spreading the wings with the sail mount tangs been detached check that the sail mount
webbing is in proper position in the slot of the end cap of the leading edge # 3.
16. Finish the assembly of the glider completely according to the normal assembly procedures.
NOTE
Secure the sail mount tangs with the nuts at the nose plates after you accomplish all steps in
section "Combat-C set-up procedure" from item 1 through item 8.
17. Do a very careful and complete preflight of the glider according to the normal preflight procedure as explained
earlier in this manual.

COMBAT-C STABILITY SYSTEMS

Several design features of the Combat determine the glider's degree of stability in pitch:
- The combination of wing sweep and spanwise twist.
- Reflex in the root section.
- Main (inboard) sprogs, and the height at which they and the transverse battens support the trailing edge.
- Outboard sprogs, and the height at which they and the transverse battens support the trailing edge.
- The shape of the preformed battens and the internal fabric ribs, and adjustment of the internal velcro attachments,
which define the airfoil.
Correct attachment and proper adjustment of the inboard and outboard sprogs are critical to providing adequate
stability at low angles of attack, particularly those below the normal operating range.

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 glider, which require it. Safety requires that your glider be fully airworthy for every flight. Nuts and bolts
must always be secure, safeties must always be in place, and damage to any part, which could compromise the
airworthiness of the glider, cannot be tolerated. If you have a question about the need to repair or replace some part
