NN.R57HR3D : NOVAROSSI REX 57 HELICOPTER 3D ENGINE

Product Information

This engine is designed specifically for the demanding performance of today's 3D helicopter pilots!
NovaRossi pipe is highly recommended for optimum performance.

Cooling head:
The cooling head of our R57HR 3D engine is made from aluminium that is been chosen for its heat conducting capacity.
The R57HR 3D cooling head is "carb-smart" ready.


Compression rings:
The ignition timing is controlled with these little rings of various thickness.
To change the ignition timing you can add or remove a ring of a certain thickness.
Note that the ignition timing is related to the percentage of Nitro in the fuel and the altitude (above sealevel) of your model.


Piston ring:
The "Dykes" type piston ring has implemented to improve the sealing between the piston and the cilinder.


Conrod:
This conrod is made from a superlight alluminium which has been checked ultrasonic to prevent premature failures. The specific form creates little turbulence inside the engine which aids the internal gas-flows.


Sleeve:
The sleeve has 5 transfer ports and is made from iron.

Crankcase:
The crankcase is made from an special alloy, developed by novarossi to make obtain the best possible strength to weight ratio.
