Stabilator Counter Balance Addendum
Note: Very early prototype models have flown dozens of flights with no stab “C” balance and
have had no flutter issues.
Adding this 2oz lead rod to the stab L.E. broadens the speed range of the F-16.
Use a Perma-Grit RF-6c to start the hole in
the stab root rib at the L.E. Use a Perma-
Grit RF-5f to enlarge the hole sufficiently to
accept the 3/8” lead rod.
Prior to inserting the rod into the stab, drill a
5/64” hole about 3/8” deep into one end of
the lead rod. Partially insert a servo
mounting screw that will serve as a handle
to maneuver the rod while gluing it into the
stab.
