Servo mounts, set, qty 4, includes - rubber isolators, brass eyelet, mounting screws, plus servo arm screw.
Note; the rubber for these
dry out and get hard over time due to ozone in the atmosphere. I
replace the ones in my own models about every two years as part of my
winter maintenance cycle - heads up! That's when you order PDRS-CM-21-mini, which are just the rubber bits.
