TUNING
Your Sting 3 was test flown and delivered to you in trimmed ready to fly. If, however, any
adjustments are made to your glider, we recommend that they be recorded in your maintenance log
at the rear of this manual.
If you feel that the glider requires adjustment to trim in the roll or pitch axis you should check that the
problem is not caused by something asymmetrical in the frame or battens. In order of priority, check
the following:
•
Ensure that the wires are correctly routed;
•
Check the battens against the profile;
•
Check that the battens have the same tension on both sides. Battens should be checked for
normal and even operation;
•
Check that the keel is straight;
•
Check that the sail is correctly mounted on the leading edges;
•
Check leading edges are straight and the rear leading edges are located correctly;
PITCH TRIM
To make the glider trim faster move the main hang strap forward and to trim slower move the hang
loop rearward. This is done by moving the king post forward or rearward, one hole at a time only.
To move the hang strap, note the current position of the king post on the keel (eg using a pencil),
unclip the front wire, let the tension off the cross bar, and ensure the side wires are loose. Undo the
nut holding the king post in place, and carefully move the king post assembly to the new hole. The
reserve hang loop can be moved as the king post assembly is moved. Re-attach the nut securing
the king post being careful not to over-tighten, inspect and test fly.
