Ed,

180 hours is about right.  I have 178 hours on my bird, a pair of tires are ready to install during the annual in May, the disks have shown wear, the pads are holding up fine.  The owner of Matco saw the installation last year
at the Hill AFB air show.  N94RJ was on static display with two other

Experimental birds and his comment was "You are showing good service on the old style rotors, make sure you change them out next annual." Apparantly the newer rotors are more durable.   the airframe was produced in 1991 serial no
170.  One tire is bald the other shows some tread so it is time to change out.  I believe you will get 180 hours if you don't jam on the
brakes to exit the first and sometimes second taxiway.  Let the plane run out and dissipate the forward momentum and use the brakes only for slight braking and directional control.  They will last quite a long time.
