The O.S. Engines 30VG ES Electric Starter was designed to use the DuraTrax Kwik-Pit Super Start for the HPI Savage or the HPI Roto Starter System. The 30VG ES Electric Starter has the same mounting dimensions as .21 size engines, making upgrading easier.

The 30VG ES Electric Starter has advanced Bi-Metallic Liner (ABL) cylinder liner construction. This process uses a double layer of plating material rather than one thick layer. This helps the metal bond to the cylinder and makes it much more durable. Also, the plating process is more consistent, resulting in a more precise fit between piston and sleeve for better compression and longer life.
