This is the O.S. Max 30VG (P) ES Electric Start, Rear Exhaust
Monster Truck Engine with Pilot Type Crankshaft.

FEATURES: Preinstalled E.S. Starter backplate is designed to use the DuraTrax
Kwik-Pit Super Start for the HPI Savage or the HPI
Roto Starter System (HPIP8711), see COMMENTS
Same mounting dimensions as .21 size engines making upgrading easier
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 is
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.
Machined aluminum piston, 3-port cylinder liner and double bushed
knife edge connecting rod
21E single needle Slide Valve Carburetor (OSMG2456) with insulated
sleeve to prevent fuel vaporization
SG (pilot) type oversized crankshaft with rubber-sealed front bearing
and oversized rear bearing to handle high torque loads
Two year limited warranty

INCLUDES: O.S. Max 30VG (P) ES Electric Start Monster Truck Engine, illustrated
manual, #8 glow plug, #203 air filter, two foam filters, two air
filter O-rings and preinstalled E.S. Starter backplate

REQUIRES: Duratrax Kwik-Pit Super Start System or the HPI Savage
Roto Starter System (HPIP8711)
Car blend nitromethane fuel with 10-30% nitromethane content,
20% nitro content recommended as starting point
Most of the fuels we carry meet or exceed the lubricant content
required for optimum performance and maximum engine life. In the
past, the conventional lubricant content used in fuel was 18%. But
with new advanced technologies, fuels like Red Alert and O'Donnell
for example, have a better quality of lubricants even though the
percentages of lubricant content are lower. These high-tech
lubricants provide exceptional cooling and protection.

COMMENTS: The manual says to install the backplate from the HPI Roto Starter
System onto the engine. This is incorrect, the compatible backplate
is already installed on the engine.
The backplate for the HPI K4.6 engine will not fit on this engine.

To use this engine on the Duratrax Nitro Warhead, use OFNG0098 Clutch
Nut.
