My 4 ele SteppIR regularly slips on the mast, and I have
to recalibrate the AlfaSpid.  It has probably made at least
a half dozen complete revolutions in 4 years.  I tried retightening
the clamps and it had no effect.  My observation is that the clamping
force is plateau'ed due to the mast/boom plate bending and/or
the U bolts stretching (or the mast flattening).  I have an aluminum mast,
FWIW.  I intend to eventually install a Slipp-Nott.
