Safety Notes
Please remember the engine is not a toy and has the potential to cause bodily harm to you
and others if misused. The MERLIN XBL SERIES is a sophisticated piece of machinery and
should be
treated with a high level of safety when it is in operation.
The following guidelines should be read carefully and adhered to.
1. Always keep a CO2 or similar fire extinguisher of at least 2Kg of CO2 contents close
when starting and operating the engine
2. Always protect eyes and ears during the starting procedure.
3. Be aware of the extreme intake suction hazard, we advise the use of a suitable
commercial wire mesh Foreign Object Damage guard to protect the engine intake. Ensure
you have no loose items of clothing (ties, etc.) or equipment which can readily be sucked into
the engine intake, even from adjacent to the engine.
4. Always operate your engine in open air away from confined spaces as the engine exhaust
contains gases which can cause asphyxiation and nuisance smells.
5. Do not touch the engine whilst it is running. Turbines rotate at a very high rpm and the
engine casing and exhaust can reach very high temperatures. Ensure anything affected by
heat is kept well clear of the engine and exhaust during operation.
6. Never use the engine near to sources of flammable gases, liquids or materials.
7. Keep unauthorized persons, spectators, children and animals well away from the starting
area (at least 30ft or 10 meters away).
8. Always handle turbine fuel and oil with care as they are highly flammable. Store them in
appropriate labeled containers. Never dispose inappropriately. We recommend the use of
suitable disposable protective gloves for the mixing of turbine oil/fuel.

Engine Description
The engine is a turbojet of a single shaft design specifically designed to power RC aircraft.
The engine starts automatically thanks to an installed electric starter situated in the front.
The starting sequence is controlled by an electronic unit that initiates the starting sequence
and controls the parameters of the engine within the design limits.
The engine uses a system of direct liquid preheating, ignited by a long life ceramic glow plug
situated inside the engine. After the initial preheat the liquid fuel is gradually introduced. The
fuel should contain a small percentage of oil and uses part of this fuel to lubricate its two
ceramic high speed bearings.
The fuel for the engine is provided from a fuel tank through a small electrical pump that uses
a three phase brushless motor. The engine speed between idle and maximum is controlled
by varying the speed of the fuel pump through an electronic controller called an ECU
(electronic control unit), that is connected to the engine trough a 3 wire digital data bus.
Installation Notes
1. The engine should be mounted using the strap mount supplied or an approved equivalent.
2. The signal cables from the engine must be carefully routed away from the engine intake
so there is no possibility of accidental ingestion of the wire.
3. Fuel pipe should be routed similarly clear of the intake.
4. The fuel pump should be preferably mounted with the spindle in the vertical position with
the motor uppermost. In the event of any fuel seeping from the pump this will not pass
through the electric motor. Note the pump is supplied fitted with built in suppression filter
to reduce radio frequency noise.
5. The centre of the fuel tank should be mounted laterally, as near to the centre of gravity
(CofG) of the model as possible. This will minimize the CofG shift as the fuel is used during
flight.
6. Any air ducting to the inlet of the engine must have sufficient diameter of at least twice
of the engine intake diameter.
7. If an extended exhaust duct is required, it should be of sufficient diameter and strength
for optimum engine performance.
8. Extreme care should be exercised to ensure that no foreign object, loose parts of the
model or debris are allowed to enter the compartment where the engine is installed.
We recommend testing the engine on a test stand prior airframe installation.
You should have a clear idea of how to arrange the components needed to run the engine
inside the model. The main issue is the fuel tank, you will need to arrange the CofG in the
centre of the tank and adjust the receiver and ECU batteries to achieve the correct
location.
M100XBL Instruction Manual M-XBL Series Instruction Manual
Electronic Control Unit (ECU)
The ECU is custom designed for the M-XBL series engines and must not be changed for
any other, as this may result in improper control of the engine. Your engine has been set up
and run with this ECU at the factory and the settings should be left as default. The ECU plugs
into your receiver throttle channel and is powered from the receiver rechargeable battery.
The ECU is pre-programmed and only requires simply setting to your radio.
Smart Data terminal
The Smart Data terminal plugs into the ECU via the lead supplied. The display can be
installed permanently on board. This socket also doubles as digital connection to a computer.
The Smart Data terminal includes dedicated screens for radio checking, last shutdown
cause and other special turbine operations. The most innovative and useful function is the
internal recorder/playback function. The terminal continuously stores all the data received
from the ecu, keeping in its permanent memory all the data of last 66 minutes of engine run,
without the need of the memory card. After the flight, the terminal can be pulled out of the
plane and, without connecting to the ecu, just using an 5-10V battery, the data stored can be
played back in real time, same presentation as if the engine was running. Playback mode
can be still, forward or reverse, speed x1, x 10 and x100 in both directions, so that would be
easy to investigate any issue at the field without the need of a computer or any other type of
reader.
Data, including all engine parameters, can be saved later to a memory card, where it can be
read using a text editor, or our viewer software. Also can be sent to engine manufacturer to
be studied, and changes uploaded back to the ecu.
Check the instructions page 24. The function of the buttons is described later in the “ECU
setup”.

Engine installation: Electrical connections
Connect the power lead of the battery to the male Multiplex socket.
PLEASE: DOUBLE CHECK THE BATTERY POLARITY BEFORE CONNECTING IT TO
THE ENGINE.
A reverse polarity connection will immediately damage the electronic components on both
the ecu and the engine. Recommended battery is a LiPo of 7,4V and at least 2000mAh /15C.
Optionally is possible to use an A123 battery of 9,9V, although the engine is happier with
7,4V. 3s Lipo is not supported.
Battery should be connected directly, DO NOT use switches (electronic or mechanical),
electronic regulators, diodes, voltage regulators, etc. Multiple battery operation is possible,
but at least one battery must be directly connected to the ecu.
Connect the throttle channel from your receiver to the socket in the ecu labeled “throttle”
and the data terminal to the socket “Terminal”. Maximum voltage at throttle input port is 10V.
Connect the fuel pump to the ecu. Check the colors. If connector is placed reversed, the
pump will run backwards.
Connect the 3 wire powerbus to the engine and to the ecu. This lead can be extended.
Although Data signal can be used with lead lengths up to 10 meters, the power looses on
power wires (red and black) will increase with length, so thicker cooper section must be used
on long lengths. Up to 1 meter, 1mm2 section is OK. If you make your own extension lead,
DOUBLE CHECK THE POLARITY. You will damage the electronics inside the engine if
polarity is reversed.

Engine installation: Fuel system
Install the fuel system components as seen in the picture placed in page 10.
Connect the fuel pump to the ecu. Check the colors. If connector is placed reversed, the
pump will run backwards.
Pump: Note that the fuel pump has an arrow engraved in the front face indicating the
direction of the fuel flow. There are 2 types of pumps. Model 1304 are used on the engines
up to 120N; model 1307 is used on engines from 120 to 220N.
Never disassemble the fuel pump, warranty from pump manufacturer will become
void.
Fuel filter
The fuel filter must be installed close to the input port on the pump to prevent any particle to
enter in the pump and to damage it. Use a suitable length of the 4mm clear tubing supplied,
keep the tubing on the suction side as short as possible. Direction of flow inside the filter is
not important, but should be always the same after first use.
Do not run the engine without the fuel filter.
Finally connect the fuel pump engine as shown. The fuel pump is a delicate element,
dropping it on the floor can damage it, always handle with care and install using the provided
mount, leave the motor part loose so that it don’t move in respect to the pump part.
It is strongly recommended that, after a new installation or modification on the fuel
system, to disconnect the fuel hose from the engine, routing it to a appropriate container,
and run the pump few seconds using the “pump test function” on the ecu so that some fuel
clean all the possible dirt particles that could have entered in the system during installation.
ECU (Engine Control Unit) Set Up
The ECU supplied is supplied programmed for the engine. The engine has already been set
up and tested using the same ECU and pump supplied so there is very little to adjust in order
to get the engine running. Confirm you have connected the ECU input to the throttle channel
of your receiver, DISCONNECT the ecu battery, and connect the Data Terminal into the
ECU. Remove all rates, mixes and throttle travel settings in the transmitter. Before doing
any adjustment on the ecu, check that your transmitter is sending the correct signal by
checking the reading of “Pulse” in the data terminal. I should be between 900-1050uS at
STOP, position, between 1100 and 1300uS at IDLE position and between 1800 and 2200 at
Full Power position. Please note that these readings on the ecu are measured directly from
the signal received from your RC system, so you should readjust your transmitter if the
values read are outside that the ones suggested. The setup assumes the use of a transmitter
with manual trims.
If you use a TX with digital trims, is essential to use the switch in the TX
programmed for the function "Throttle cut", or “engine cut” which normally has the
effect of producing the “trim-down” function. Using a digital trim cause unstable idle,
and excessive delay in shutting off the engine in emergency.
Check your radio manual for this before you start. DO NOT use the digital trim in any
case.
