Novarossi Mantra 3.5cc off-road engine
Novarossi have announced that their Mantra 3.5cc nitro off-road engine is now also available with a rear ceramic bearing. The square stroke power plant is of a 4-port design and it comes with a specially shaped crankshaft for optimised mixture flow, a rear crankcase cover with steel insert for reduced friction and with an O-ring sealed composition camber insert for reduced vibrations and better sealing. The ceramic rear ball bearing will minimise wear while improving acceleration and fuel consumption.
