I beefed up the link mounts a little on these. This is our BOA/servo mount for the Super 8 axles. Will allow a small 2-3s battery to be ran on the axle opposite of the servo. Depending on servo and shocks used modifications to the mount, shocks or spacers may be necessary. Servo attaches with m2 screws(not included). Remember, this is a printed mount and is not built to survive numerous tumbles.
