Bolt That Servo Horn Quick Pit Tip

Often servos come with an insufficient servo horn bolt for racing purposes. That tiny Phillips head bolt that came with the servo is more prone to stripping and also letting you down in the final turn. Most metal splined servos can use common 3 mm motor Allen hex screws that offer 2.5 mm of grip. This allows for a better connection, and is much less prone to damage. In the photo above I am replacing the stock bolt with a Lunsford titanium screw for both increased durability and weight loss. A very minimal amount of blue (temporary) thread locking compound should also be used, however this is one area that you do not want to go overboard. Last, ensure that the screw is the  proper length for your application or damage may result.

Note: This tip is not recommended for Nylon splined servos.
