Loctite
Roger,
When I did my annual, this month, I found a quarter inch slop in the
starboard tailplane. Not wanting to rip everything apart, I decided to
use the Loc-tite method. What I did was to spray out the parts with
automotive choke cleaner, being careful not to get any on the paint.
Then I blew it out with compressed air and allowed it to air dry for a
hour or two. I then started saturating the joint with Permatex's
version of 603. It's the wicking type (green) found in most automotive
parts stores. After I was satisfied that I'd gotten as much in as I
possibly could, I let it set for 24 hours. Checking the joint by
twisting as hard as I could, nothing moved. I've got 6+ hours on the
repair with probably 10 landings and no movement at all. I check the
tailplanes every time I do pre and post flights. They are tight - no
movement. My bird is a tri-gear with steel spring front suspension.
Flights have included 45-50 degree turns and other 2+ G maneuvers...
Hope this helps,
Jeff - Baby Blue
