These are motor soft mount pads to help reduce vibration to your flight controller.
Some people like to soft mount their flight controller completely and some their motors.
Both work great. Just put these pads under your motors on top of the carbon and bolt your motor on like normal! Enjoy!
Package includes: 8 pcs.
WILL ONLY WORK WITH 16X16 BOLT PATTERN MOTORS LIKE THE HYPERLITE LINE AND SIMILAR MOTORS
