ImpulseRC Apex Soft Mount Arm Guards (Set of 4)
These are soft mount arm guards made for the ImpulseRC Apex frame. They are great for protecting your arm ends from cracking and splitting. They also double as a motor soft mount to dampen vibration. If you choose to not soft mount, you can install the arm guards upside down.
The arm guards are also available in a version that has no lip that wraps over the carbon fiber arm so that you can still use the stock injection molded arm skids.
