evoJet 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. The heat causes the air to expand rapidly, enabling it to drive an

axial turbine rotor, which in turn drives the aforementioned compressor via a shaft (open circuit gas

turbine).

At the exhaust cone, the hot air leaves the engine at a speed of more than 1000 km/h (620 mph),

generating the required thrust for the jet aircraft model. An electric starter motor and a new electric

kerosene ignition system allow fully automated engine control from the R/C transmitter, controlled

and monitored by the JETRONIC control unit, which regulates all operating parameters to their

optimal values. This new generation of model jet engines does not require dangerous auxiliary

gases like propane or butane any more. Power is supplied to the engine by a separate

rechargeable lithium manganese battery, which is used to power all system components, such as

fuel pump, kerosene ignition, valve etc.

State of the art precision CNC and laser cutting technology allow a previously impossible

production accuracy, ensuring both high performance and durability. The included display and

programming unit (EDT = Engine Data Terminal) is equipped with an illuminated LC Display and

can be connected to (and disconnected from) the running system at any time to check the current

operating data or to change parameters. Besides the current operating parameters, such as

exhaust gas temperature (EGT), turbine revolutions per minute (rpm) and thrust (throttle),

additional information like total hours of operation, rpm and temperature statistics, number of

engine starts, battery voltage etc. can be displayed as well.

All parameters and user entries are displayed in plain text in a menu based interface. The turbine

is started fully automatically via the throttle stick on the R/C transmitter. The pilot then adjusts the

desired thrust by moving the stick proptionally. The JETRONIC control unit is connected to the R/C

receiver via R/C 1. R/C 2 can be connected optionally for switching functions.

IMPORT NT NOTE:

Operating a jet aircraft model requires greatest care and special knowledge. When

installing and operating your jet engine, always observe the safety rules in this manual !

Warnings and Safety Notes

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. Since it is a genuine jet engine, it requires know how,

discipline and regular service and maintenance – for your own protection and that of other people.

If you want to install and operate this jet engine in your model aircraft, you mus be trained in its

handling. The model with the jet engine should only be operated under supervision of an

experienced person, who can support you in order to avoid mistakes. If there is a local R/C club in

your area offering training and support, we recommend that you become a member. Mistakes

made during the assembly or operation of a jet powered model aircraft can lead to serious injuries

or even death.

lways observe the law

Before operating a model aircraft with this jet engine, you should be informed about the legal

regulations regarding such aircraft. From a legal point of view, a model aircraft is considered an

aircraft like any other in most countries and is subject to the corresponding laws, which must be

observed by all means. Please check the applicable air traffic laws of your country carefully before

flying your model. Your local R/C club will likely be able to provide you with the required info

rmation and documents. In many countries, jet powered model aircraft require a special licence

and/or a special insurance. Furthermore, regulations regarding the protection against interference

between R/C transmitters and radio networks must be observed. Please make sure to comply with

all applicable laws and regulations in your country.

C UTION – keep a safe distance!

It is your responsibility to protect others against injuries. The operating distance of your aircraft

from residential areas must be at least 1.5 km (1 mile) in order to ensure the safety of people,

animals and buildings. Keep a safe distance from power lines. Never fly your model in bad weather

with low clouds or fog. Never fly directly against the sunlight – otherwise you might lose visual

contact with your model. To avoid collisions with manned or unmanned aircraft, land your model

immediately if an aircraft is approaching. Persons and animals must keep the following minimum

distance to the jet engine (see also the figure on page 6):

In front of the engine: 1 m (3 ft)

At the sides of the engine: 12 m (36 ft)

Behind the engine: 10 m (30 ft)

evoJet B90 – B130vx – B160vx – Instructions 4.0

W RNING !

Operating the model and/or the jet engine under the influence of alcohol, drugs etc. is strictly

forbidden. The jet engine may only be handled by persons with an excellent physical and mental

condition and concentration. This applies to the operator as well as any assistants.

This jet engine was designed solely for use in model aircraft and is not suitable for any other

purpose. Never use it for persons, objects or vehicles other than suitably constructed model

aircraft, as any other use can lead to personal injury or death.

Any deviation from the specifications in this manual, the use of non approved parts or materials or

modifications to the system construction or setup can have a negative effect on the functionality

and safety of the jet engine and must be avoided by all means.

W RNING !

The jet engine may only be operated in exact compliance with the instructions in this manual.

Furthermore, the specifications of the aircraft model regarding the centre of gravity and rudder

manipulations must be adhered to. The configuration recommended by the model manufacturer

must be observed. Before taking off with a model equipped with this jet engine, all functions and all

rudders as well as the range of the R/C transmitter must be tested with the transmiter turned on

and the antenna retracted. This range test must be repeated with the jet engine running while

another person is holding the model in place. Furthermore, the instructions by the R/C system

manufacturer must be followed closely.

Safety Notes

✔lways have a fully functional CO2 fire extinguisher with at least 2 kg (4.4 lb) of filling

weight at hand.

✔Only test the jet engine at suitable places outdoor and observe the applicable laws

and regulations.

✔lways keep the following safety distances from the running jet engine

(1 m = 3 ft, 10 m = 30 ft, 12 m = 36 ft):

✔Never look straight into the exhaust jet and never touch it with your hands.

✔Whenever possible, wear hearing protection.

✔Keep away from the engine intake (electric starter). The air stream has an enormous

suction power, which can lead to severe injuries.

✔fter the first installation, and afterwards in regular intervals, test the transmission

range of your R/C system with the jet engine running.

✔Before operating the engine, remove all loose objects near the engine intake, such

as cleaning cloths, screws, nuts, cables or other material. Before operating your

model for the first time, make sure that there are no loose objects in the engine

intake, such as clippings, screws or swarf from building the model. Such objects can

damage the turbine. When installing the engine in your aircraft model, cover the

engine intake and exhaust opening, for example with adhesive tape, to keep

clippings/swarf and other objects from entering the engine.

✔Make sure that about 5 % of turbine oil is added to the fuel. Use prefered special

aircraft turbine oil like EROSHELL 500/560.

evoJet B90 – B130vx – B160vx – Instructions 4.0

Warning:

Compared to an ducted fan model aircraft, the model with a real jet engine reaches much higher

airspeeds due to the considerably higher exhaust speed at the same static thrust. The achievable

airspeeds of more than 300 km/h (190 mph) normally exceed the speed range an aircraft model is

approved for (risk of rudder flutter, sudden nose dives and overload of the fuselage and the

servos).

Therefore always take care of the following: After taking off and accelerating to normal airspeed,

always pull the throttle back. For horizontal flight, 50 % of thrust is sufficient to achieve the same

flight performance as with an ducted fan !

Only use the full thrust of the jet engine for takeoff and for vertical climbing in aerobatics!

For limiting the airspeed, we highly recommend using the optionally available Airspeed Sensor

(part no. 8135) !

Warranty Conditions
