This is the Novarossi Mito 4 Tuned 4-Port .21 Off-Road Nitro Engine, with front and rear Steel Bearings. Introduced for the 2015 season, Novarossi presents the Mito line of on-road and off-road engines. Features include the exclusive shifted patented carburetor design, updated rear ball bearing design, improved cooling head and updated 3 needle carburetor. All these features help the Mito provide improved fuel efficiency and an optimized power curve.


  • Patented Carburetor: The shifted carburetor grants a better mixture flow inside through the crankase's intake. This gives the engine an improved fuel efficiency and a better power curve.
  • Rear Ball Bearing: The updated ball bearing reduces the inertia of the rotating masses and increases the engine's scavenging. These novelties give an increased throttle response and a higher top speed.
  • Cooling Head: Featured on the Mito 4 is an updated cooling head that has been heavily milled for reduced weight and enhanced cooling properties.
  • Carburetor: The carburetor of this engine is made from plastic and in "reverse" style and has a sliding throttle valve. The updated three tuning needles gives a better idle and improves the ability of the engine to return to low rpm after throttling.
