3W 70iB2 CS Engine with Electronic Ignition
The engine is ideally suited for towing and 3D flights as well as for flight models with a mass of up to 10 kg. Here the engine distinguishes itself with extreme running smoothness and a very good me-dium-range running characteristics.
The 3W Competition series (CS version) distinguishes itself through greater performance, more rapid response behaviour, and high torque. The engine thereby achieves a high standard of per-formance. Transfer ports in the cylinder and crankcase are modified.
