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.

Ultimate Jets B300F User manual rev5. 1st June 2014 4

Follow the Safety Rules!

Non-adherence of the following safety rules can be fatal!

This device was manufactured to the highest current technological
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!

Ultimate Jets B300F User manual rev5. 1st June 2014 5

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

Ultimate Jets B300F User manual rev5. 1st June 2014 6

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!).

Ultimate Jets B300F User manual rev5. 1st June 2014 8

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 non­flammable 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.

Ultimate Jets B300F User manual rev5. 1st June 2014 10

2.3. Assembly of the complete system

 Please look at the installation schematics number 1 as well as

the installation picture number 2 in the appendix section.

 The optimum size of the fuel tank depends on the model but

should be at least 2.5 liters. The optimum size for the

B300F

is 4 - 5 liters, which is enough for an average air time of 6 – 8
minutes, depending on your style of flying. For further
information please see technical data, fuel consumption. There
must be a clunk in the tank.

 The tank set up should be made using a new generation

hopper tank. Please refer to the installation schematics "
engine fuel supply". All the fuel lines and vents must be of at

least 4 mm ID.

 Use yellow, highly flexible Tygon tube, attach it to the pump

and secure with safety wire. Fuel system accessories can be
found in the Ultimate Jets line of products.

 The fuel pump must be installed directly after the hopper tank.

Be careful to install the pump correctly (brass fitting = draw
side). The electric wiring of the pump hast to be done with the
correct polarity (+ / -). If the pump is not wired correctly, it will
not work properly and will transport no fuel

 Install the fine filter on the pressure side downstream the

Hausl fuel pump (side out). Install, a Y Festo quick connector
downstream the filter; using the red and blue 4mm tubes
provided. Plug each tube to a fuel valve, respecting the flow
direction engraved on the valve ( thin arrow engraved on the
top of the valve ).
The electric connection of the main line valve should be made
at the ECU “KERO VALVE” input. The fuel line should be
connected to the turbine using the engine quick connector

labeled „ KEROSINE “

The electric connection of the start line valve should be made
at the ECU “PROP-VALVE“ input. The fuel line should be
connected to the turbine using the engine quick connector

labeled „IGNITION“.

Ultimate Jets B300F User manual rev5. 1st June 2014 11

 All FESTO quick connectors (blue head) are self-locking.

They are connected and disconnected this way:

Insert the tube strongly. There should be no resistance felt for
the first 6mm of travel. However on the next 6mm
(approximately) resistance should be felt. Only then the tube is
perfectly locked in.
For release, push the blue cap in the direction of the
connector's body and remove the tube by pulling.

 Now the turbine should be electrically wired to the ECU:

Connect the turbine via power lead to the ECU at the Glow /
Starter output. Also connect the black data cable to the turbine
and the Sensors input of the ECU.

 Connect the I/O Interface with the ECU at the “Terminal“

connection. Then the data terminal can be connected to the
I/O Interface. The I/O Interface serves as control interface; it
features acoustic and optic control. The data terminal does
not need to be installed in the model for day to day operations.

 Power supply:

Rechargable batteries of at least 30C rating and 3500 mAh and
up to 5500mAh of 3 cells type must be used.

We recommend high rating 3S Lipo and a maximum of 12 volts.

Connect the battery to the “BATTERY” input of the ECU. Use

a high quality pure copper or silver cable of gauge cable of 10
AWG, especially if the distance between the battery and the
engine is long.

Disconnect the battery from the ECU when not in use to
prevent discharge. Check for the right polarity at power plug!
Long battery wires should be twisted!

 Finally connect the receiver to your ECU. The cable is welded

on the ECU. Only use original adaptor cables if other receiver
plugs are necessary. The ECU is only operated by one input
channel (engine power limiter).

Ultimate Jets B300F User manual rev5. 1st June 2014 12

3. First Turbine Operations

3.1. Initial steps

 Fill the fuel tank with kerosene. Ensure a 5% oil mix.
 Make sure the tank breather is open!
 Filter your fuel when filling up using a line filter on your jerrycan.
 Make sure that both the ECU battery and the receiver battery are

charged.

 Test your remote control range with and without the ECU turned

on.

 Always place the model with the nose into the wind and make

sure that the jet blast will not be set in the direction of persons or
equipment.

 Turn the transmitter and the receiver ON.
 The Pro-Jet ECU is mostly pre-adjusted and tuned to your

turbine. If the unit starts in German, you can change the

language to English in menu 3.2 ( System-> Sprache ).

 However you'll have to teach your remote control unit throttle

range to the ECU. The failsafe range should be programmed at

this stage. Please refer to 3.3 below. Then, follow the ProJet

instructions on page 16, to learn RC from menu 2.1.

 It is necessary to prime the fuel system before the first operation

in a new model. That means both starter and main fuel lines must
be filled with kerosene up to the engine. Priming is done
manually with throttle back, and trim low on the transmitter. Press
the small black smc push button on the left side of the I/O board.
This will open both fuel valves and start the pump. Check the
kerosene progression in the lines carefully to prevent the turbine
from being flooded. Stop priming just before kerosene enters the
turbine. Do not pump kerosene into the turbine.

 This procedure must be done before the first engine run as well

as if dry running has occurred due to tanks emptying or
unpriming.

 Should the turbine have been flooded, place the model with the

nozzle facing downwards ( nose up ) to allow excess kerosene to
exit the turbine. This should avoid a hot start, that can damage
the turbine.

Ultimate Jets B300F User manual rev5. 1st June 2014 13

3.2. Starting your turbine

 Be sure to have a fire extinguisher (CO2) within reach.
 The ECU runs through an automated calibration routine to

adjust fuel metering to outside air parameters as well as tube
length. The Hornet III ECU, does this routine at every start.

 On the first boot-up the ECU will adjust the temperature probe

and the pump's starting voltage.
The turbine is then ready for start (green I/O LED ON ).

Set trim to max, then throttle to max. The terminal will indicate
"STANDBY". The ECU is waiting for your order to start ( red I/O
LED ON ).
Simply retard throttle stick to minimum and within three seconds

to full.
The starting sequence will run. See the Pro Jet instructions (page

26).
Note that during the sequence, the turbine will calibrate for idle

and mid rev at ca. 60 000 rpm. Hold or adjust your model for this
procedure. The procedure can be interrupted any time using
emergency stop by pulling the trim and throttle stick in the aft
position.

 After that auto calibration routine, the turbine can be controlled

with the throttle ( red I/O LED OFF ).

 All the parameters necessary for the turbine's safe operation

are now controlled by the ECU.

 Conduct a test run of your turbine, possibly while testing the

range of your model.

 Shut off the turbine at mid rev range. This is done by putting

the throttle stick to mid position, then setting the trim back all
the way and then pulling the throttle stick back to idle position.

An engine shut-off from medium rotation speeds achieves a
gentler cool down of the rear ball bearings and the whole
system.

 Put the model against the wind and wait until the after cooling

process is over (around 2 minutes). When completed, you can
turn off the receiver unit.

 Check the model’s fuel supply connections and de-fuel, if

necessary.

Ultimate Jets B300F User manual rev5. 1st June 2014 14

3.3. Control Functions and failsafe

 In case of error, check the ProJet manual. From p. 16 onwards

you will find some concise error descriptions and explanations.

 Transmitter signal lost: Auto shut off happens if the transmitter

signal fails on PPM receivers. Attention! With PCM receivers,
the fail safe function should be programmed to idle in order to
avoid emergency stops upon intermittent receiving errors.

 With 2.4 Ghz receivers, the throttle range has to be

programmed and failsafe position teached to the transmitter.

 Setup the throttle ATV from the transmitter at +- 150%. Then

program the failsafe throttle point at -150%.

 Adjust the throttle ATV range back to +- 100%. Make sure that

no throttle curve is programmed in the transmitter. Learn RC
from the ECU ground support unit in menu 2.1. Please refer to
the transmitter user manual to set the failsafe point.

 The fail safe auto shutdown must be checked at the field. With

the turbine running, switch off the transmitter and make sure
that the turbine shuts down. The ECU status should read

"failsafe" and the I/O board should beep continuously. This is

an AMA requirement.

3.4. Tuning Options / Electronics

 Please refer to the Pro Jet manual for tuning options. You

should study the latter carefully.

 Avoid a system reset!!!

As a result, the ECU may have to be updated at the Ultimate
Jets factory again.

 The ECU features a code controlled menu system. Every

number features an individual menu point. From these menu
points you have options of changing different pre-set
parameters. This should, if at all, be done very carefully
because the factory setting of most parameters is already
optimal.

 The following parameters are to be verified, i.e. changed, also

after a system reset (see attached sheet).

3.1 Battery voltage

2.3 Adjustment of the temperature probe

2.2 Glow voltage

2.1 Pulse width of the sender signal

1.4 Pump starting voltage

Ultimate Jets B300F User manual rev5. 1st June 2014 15

4. Maintenance Instructions

4.1. Correct Maintenance of Your Turbine

BF turbines only need little maintenance under normal operating
conditions. However, some points must be considered to guarantee a
faultless operations of the engine. This includes regular cleaning and
inspection.

 Dirt and grease deposit can cause slippage of the starter unit

clutch. If this happens, clean the rubber o’ring and the

compressor nut with a degreaser like alcohol or naphta.

 The felt clunks mounted into the tanks should be cleaned or

changed after 10 hours of operation.

 The pressure line filter between the pump and the turbine

should be cleaned every 5 hours of operation.

Do this very carefully and make sure that no particle will
enter the fuel supply tube. Destruction of the turbine could
result!

Make sure the o-ring is in the correct position when screwing
the filter back together. Check for leak integrity!

 Cover the intake and nozzle areas when the turbine is not in

use.

 Keep the turbine in a dry and dust-free environment when it is

not used for a longer time. We recommend a dehumidifier to
prevent corrosion.

 Check the battery condition regularly.

 Your turbine’s maintenance interval is at 40 to 50 hours

(about 300 flights). After this time as well as after a special
event (crash, etc.) the turbine should be returned to the
factory.

Ultimate Jets B300F User manual rev5. 1st June 2014 16

4.2. Repair Work

Repair and maintenance work which include the disassembly of the
turbine must only be performed by professional personnel.

Please contact Ultimate Jets with all service related questions.
Warranty return can only be carried out by Ultimate Jets for the USA
Maintenance and repair work performed by non authorized personnel will

void the warranty.

6.3. Other considerations and pictures

When the turbine is not used or
returned to the factory, the kerosene
and propane joints must always be
sealed. Please use included plugs.
Miniscule particles can clog
kerosene tubes and fault free
operation of the turbine cannot be
guaranteed.

Repair costs of up to 360 Euros
can be the result.

Tank size must be determined by
the user. See technical data, fuel
consumption. Usually 2 – 3 liter

tanks are used with

B300F

turbines. Drill a 6 mm hole in the fuel
tank cap of your choice.

Use the included tank pendulum
device and screw it together with the
tank cap. Check for tightness.
Cut a piece of Tygon tube with a
length of ca. 120 – 150 mm. This is
the ideal length for the typically used

1.5 liter and 2.0 liter Coca Cola
bottles. The length of the tank
pendulum, however, depends on the

type of tank used. We recommend
to choose the length the way that the
felt pendulum lies at around 75% of
the tank length.

Now place a 6mm flat washer on the
felt pendulum and connect it with the

Ultimate Jets B300F User manual rev5. 1st June 2014 28

Tygon tube. This will prevent slippage of the felt body.
Then secure the Tygon tube connections with wire. Again, check for leak
tightness.

Weld the battery cable to your chosen
battery. Red = plus, black = minus.
We recommend a good quality 3S
Lipo of a capacity of at least
3500mAh and 30C discharge
capacity have proven to be ideal for

turbines of type

B300F

. Energy
consumption is roughly 450 – 550
mAh, depending on your style of

flying, for a 8 minutes flight and cool
down period.

When using a nozzle extension with
your model, the diameter of the
extension pipe and the distance from
nozzle to nozzle extension must be

correct. With

B300F

turbines the

entry diameter of the extension pipe
should be around 130mm while the
end diameter should measure around
110mm. The shorter the nozzle
extension the smaller the loss of
power.

When using BF Turbines nozzle
extension pipes for

B300F

type

turbines, the distance from the end of
the aluminum turbine housing to the
aluminum hopper should be 3 – 4 cm.
The extension pipe must be securely
attached to the model.
