REFLECTOR: Tips on stop drilling for cracks in the wind screen

[Brian Michalk]

I forgot to mention ... before you do this.

Check your keel where you cut out the section for the push-pull elevator 
tube.  See if your keel has deformed around this cutout area.  A hard 
landing puts the keel in compression at the top.  If the keel doesn't 
keep the canard bulkhead in its place, then the fuselage may deform 
right there at the corner of the windshield.
