B90 – B130vx – B160vx – Instructions 4.0 Introduction The model jet engines of the evoJet-VX series uses the same functional principle as a "big" jet engine. A high performance compressor compresses ingested air, which is then heated by a fuel flame in the combustion chamber.
Welcome to the era of model jet aircraft! Please never forget: Operating a jet engine like the evoJet-VX can be dangerous. An aircraft model equipped with the evoJet-VX can reach speeds of more than 400 km/h (250 mph) and temperatures up to 500 °C (930 °F) at the engine housing and up to 750 °C (1380 °F) at the exhaust jet.

The operation of the aircraft model and the jet engine takes place solely at the operator's own risk! By operating the jet engine, you confirm to be aware of the fact that evoJet cannot supervise or control the compliance with the instructions in this manual regarding assembly, operation and use of the aircraft model, jet engine and remote control unit.

B90 – B130vx – B160vx – Instructions 4.0 Airspeed Sensor [8135] The JETRONIC-Vx allows the connection of an optional airspeed sensor to the AUXiliary con- nector. For the measurement, a pitot tube (Prandtl type) and an electronic pressure sensor are used.
Page 32
B90 – B130vx – B160vx – Instructions 4.0 Hints In order to achieve a precise airspeed measurement, the pitot tube should measure the stagnation pressure possibly free or only on parts that are parallel to the incoming airflow. Do not mount the tube on conical areas.
