A CNC machined aluminium X mount for brushless outrunners with a 30mm diagonal bolt pattern, countersunk on both faces. Black anodised, 4mm thick.

The motor bolts to the four inner holes, the arm tips bolt to your firewall or standoffs, and the open centre clears the shaft and bell. Stiffer than the plywood or plastic mounts supplied with most ARFs, and it won't crack around the screw holes after a season of vibration.

This is the dual-sided version. The firewall holes are countersunk on the front face and the motor holes on the rear face, so each screw head recesses on the side it actually sits on and both mating surfaces finish flush — nothing stands proud against the firewall or under the motor. If you only need recessed heads on one face, the XMM30A does the same job for less.

The holes take M3 or M4 screws, so this mount suits larger motors than the 25mm pattern typically carries.

Check your motor's bolt pattern before ordering — spacing varies between manufacturers.
