importance of a thorough pre-flight cannot be over emphasized. You
should follow the factory recommended pre-flight and develop a systematic, habitual approach. Once established,
never vary from your method and of course, always do your own
at the nose of the craft and during your pre-flight, work around
the Ouicksilver MX in a counter- clockwise manner. If any
questions arise, consult the assembly instructions.
Checking the "integrity" of a tube means to check for
bends, dents, scratches, etc. Checking the "integrity"
of a wire means to check wire ends for bolt and/or other
fastener security, and to check for twisted or jammed thimbles.
Wires should be free of kinks, frays, abrasions, broken strands,
etc. Wires should be free of sagging, but not so tight that they
"twang" when plucked.

contains impurities, drain until contamination is gone. Remember,
water in the gas can cause engine failure!
Check pull starter and all engine components for obvious problems.

This suggested outline for a Pre-Flight Inspection generally
covers the critical areas that MUST be checked prior to each
flight. In addition, EVERY component must be examined after
construction, properly maintained, and correctly stored or
transported to ensure structural integrity and safe flying
characteristics of your Quicksilver MX
