API Flange Mounted Quick-Change Motor Retainers in sizes from 54mm through 150mm
There is a flange on the retainer body that attaches to the lower centering ring instead of bonding to the motor mount tube. Stainless steel socket head screws and threaded inserts are included. Like our standard 24mm through 75mm motor retainers the flanged motor retainer assemblies have screw on caps for fast, tool-free motor change. Minimum airframe ID`s are as follows: RA54 = 3.000" min, RA75 = 3.875" min, RA98 = 5.000" min, RA150 = 8.500" min.
