Roto Motor 70cc V2 Gas / Petrol Twin Cylinder 2 Stroke Engine
ROTO motor 70 V2 is two cylinder 2 stroke gasoline engine made specifically for the model airplanes up to 3.2 m (10.5’) and 20 kg (44,2 lb). These dates are for recreational flying.
The Engine was developed in Europe with the assistance of CAD systems (Solidworks) and optimized for the liquid flow in the Flow software (made by Solidworks).
All ROTO engines and its components are made and programed by utilizing the state of art 5 axis machinery made by American companies HASS and Siemens NX.
Every engine, made by ROTO MOTOR Company is bench tested and adjusted by qualified technician on the Engine Star equipment to ensure its peak performance.

Manufacturing technology ROTO 70 V2
- Crank case (kit) – it is rough-worked of the cast at the CNC milling cutter. After that it is covered or slashed with a special colour. Cylinder (roll) – it is made of one piece of dural with pressed insole from the mild-granular cast iron, it is sharpened and honed to the correct size.
- Piston – it is casted from silicon alloy with one sealing circle. The aparature for the bung 8 mm is honed.
- Piston rod – it is forging, which is completely worked. Two needle focuses are moulded into piston rod, it is made for the piston and cranked bung.
- Crank shaft – it is made of one piece of steel, it is cemented and hardened and it is completely sharpened.
- Back lid of the engine – it is worked casting, in which is hardened and sharpened rolled slide - valve layed.
Pieces of engine are after clearing by the scan pieced together in preparations at the special workplace.
