Dick,
By the way. Are Rogerson Kratos units fitted to any current production aircraft?
Apparently: Bell 412, Bell 427, Bell 430, Agusta A109E Helicopter, USAF C-18, Zeppelin NT, Boeing 727, 727 Simulators, Gulfstream 62, S-60, AS332, Erickson Air-Crane, Zeppelin LZ-07
I think you are chasing things the wrong way - go back to your friendly Agusta dealer and get Standard Exchange and suck it up.
RK probably have no connection or interest in the "end user".
I deal with Thales gear all the time and just do "standard exchange".
Fixed price - move on.
Getting your own gear fixed is the old way of doing things - we just change black boxes these days.
Plus it will be at the latest mod status.
