1. Directions for safe operations
1.1. General safety instructions
The jet modeler in the USA shall comply to the AMA rules for turbine
models operations. We require our customer to reading and complying
with the docs and regulations enclosed on this page:
http://www.modelaircraft.org/documents.aspx#Turbines
The operation of any jet engine can be dangerous. This also holds true for
the B300F . During operation, the jet efflux and parts of the jet nozzle
become very hot; the nozzle can reach up to 700 °C. In addition, the
turbine fans do reach very high rotation speeds, which leads to extreme
tensile loads and temperatures. Therefore, it cannot be excluded that parts
of a failing turbine fan wheels or broken fans could strike through the
housing which can lead to damage and even injury or death.
Study the operation mode and the dangers of operation before using a jet
engine. In case you have no experience with the operation of gas turbines
and jet engines, instruction by an experienced person, especially before
initial operation, is mandatory. Errors in mounting and operation of a jet
engine can lead to damage, injury, or death.
Follow AMA regulations concerning aircraft, the operation of jet engines,
and the handling of combustible liquids and gases. You are exclusively
responsible to have sufficient insurance when operating aircraft. You are
also responsible to protect other persons from injury and danger.
Operating personnel and their assistants must be in best physical and
mental condition and pay full attention to the operation.
This engine must only be used for unmanned operation in R/C aircraft.
The instructions in this manual must be exactly followed.

standards. It must only be used for the purpose it was designed for.
This device can, however, be a danger to people, animals and things
when
not operated according to the purpose it was designed for
the instructions in the manual are not correctly followed
it is changed or rebuilt
This manual introduces you to a safe operation of the device.
Therefore, careful reading and thorough understanding of the manual
is vital before operation the device.
Every person who is involved in the operation of this device must read this
manual, especially the instructions for safe operation.
Furthermore one has to follow the laws and general rules of
the avoidance of accidents
technical safety, as generally valid and accepted
the country one wants to operate the device in
Moreover,
jet engines and turbines in general must only be operated with
the highest diligence
ear protection must be worn during operation to avoid hearing
damage
indoor operation is forbidden
a fire extinguisher (CO2) must be within reach!

1.2. Warning
Consider the basic differences between gas turbines and piston engines.
Turbines will deliver power only at high rotation speeds. Then there will be
a lot of power (see diagram).
Higher loads occur when driving an R/C aircraft model with a turbine
compared to equally powerful drives like propellers or impellers.
This is a result of considerably higher air speeds caused by jet propulsion.
Maximum speeds under jet propulsion can exceed 200 mph, depending on
the model. We would like to remind you that the AMA has issued strict
rules regarding maximum speed for operating turbine powered RC
models. Please refer to the AMA regulations from the link posted above.
Servos should be carefully chosen, at least 1.5 times as strong as for
comparable models with conventional engines. Ultimate Jets supplies a
set of tools to compute servo torque requirements and choose the proper
servo for the task. Please refer to our technical publications.
During installation, seal the intake and nozzle, as well as kerosene joints
to keep dust and debris out of the engine.
Really make sure to:
first inform, then buy
have the fitting size model for your turbine
select servos that are powerful enough
construct servo wiring and rudder joints very carefully and
reinforced
seal the turbine during the installation process

1.3. Before starting the engine
Tank system, pump, shut-off kerosene valves and turbine must
be checked for correct alignments.
Loose parts in the intake area must be fixed in a way they can
never be sucked in. Loose parts or dirt can damage or destroy
the turbine. recommend the use of a FOD screen.
Have a fire extinguisher (CO2) within reach!
The kerosene system must not be leaking.
Use only kerosene or Diesel with a 5% ratio of oil (fully
syntethic 2-stroke mix oil or turbine oil).
Take off must be against the wind.
Hold the turbine with the nozzle facing downwards right before
starting so that any excess of fuel can run off to avoid a hot
start of the engine.
1.4. During operations
Always stay in front of the turbine (intake facing), never to the
side or in the exhaust area of the turbine.
Also make sure that no other persons or animals are present in
the mentioned dangerous areas.
Keep your hands and every kind of object out of the area within
20 cm of the compressor (intake). The enormous suction can
grasp everything within reach and cause severe injury or
damage.
Never look into the jet exhaust. Severe burns could result.

Ultimate Jets B300F User manual rev5. 1st June 2014 7
1.5. After shutting down the engine
Place model with the nose facing the wind. Wait until the
cooling down process is completed.
Be aware of the cooling process after engine shut down.
During this process, the electric power supply of the receiver
and the ECU must not be turned off. The cool down process
takes 1 to 2 minutes, depending on the outside air
temperature.
Do not touch the turbine during the cool-down because the
danger of burning still exists.
All tube connections must be inspected for leakage after each
flight. The fuel tanks must be emptied in case of extreme
outside air temperatures or when there is no further operations
planned for the day (danger of explosion!).

2. Installation of the turbine
2.1. Attachment Options
The frame to bracket attachment points must be parallel (check
before fastening). Otherwise uneven tensions could damage
the engine casing. The B-300F generates so much thrust that
the included bracket is not sufficient to hold the engine.
IT IS ESSENTIAL TO SECURE THE ENGINE WITH AN
ADDITIONAL AND REDUNDANT FASTENING SYSTEM. SEE
THE TWO OPTIONS BELOW ( SILICON GLUING OR
ADDITIONAL TABS )
Attach the turbine only with the provided bracket, screws and
washers (see picture 2). Use a thin bead of Loctite 5940 high
temperature silicon between the bracket and the engine
casing. Please apply a thin coat of wax on the engine casing at
the glue bead location before fastening the bracket on the
engine. This way the bracket can be removed relatively easily
from the engine.
Should you want to avoid gluing the bracket on the engine, you
can use the securing tabs provided with the engine in a
separate bag and follow the specific instructions included with
the set.

Ultimate Jets B300F User manual rev5. 1st June 2014 9
2.2. Engine mounting rules
The engine must be installed in a way that the fuel starter tube
is in the 12 o'clock position. This is absolutely vital for proper
kerosene start on the B300F engine. Otherwise, the start, i.e.
the ignition, would fail and might even lead to engine damage.
There must not be any flammable objects near the turbine. The
turbine must not be touched by flammable objects.
The nozzle and the whole area in the neighborhood of the jet
exhaust must be kept clear of any objects.
In case of mounting within a bypass enclosed system, the rear
end of the installation area and any parts which could be
affected by the hot jet exhaust should be protected with non-
flammable materials (danger of fire!). When an extension of the
nozzle is necessary, it must be constructed and installed
according to the manufacturer’s specifications (overheating!).
The turbine must be installed in a way that it can be cooled by
a bypassing air stream.
Combustible liquids and gases as well as tanks and tubes must
be kept away from or installed at a safe distance from the
engine.
The intake area (impeller / compressor) must be kept clear.
Any wires, tubes, etc. must be installed and fixed in a way they
cannot be sucked into the turbine. In general, there should not
be any objects or installations close to the front end of the
turbine.
The intake section of the model should have at least twice the
area of the impeller/compressor wheel.
You must make sure that no objects, e.g. rocks, dirt, screws,
etc., can be sucked into the turbine. It is a good idea to protect
the turbine intake with a Foreign Object Damage screen (see
accessories for FOD screen).
The intake area must absolutely be kept clear. The vacuum
generated by the intake is very strong. Make sure that the
intake duct is reinforced with carbon fiber, especially if it is
long.
