Introduction
This manual is intended to aid the user in setup and running practices associated with the
SWIWIN SW and CRX series micro turbines. This manual is not intended to take the place
of a primer on micro-turbines. It is assumed that the user has working knowledge and
experience with turbines and that each user is familiar with best practices before attempting
to run a turbine.
Non- Disclaimer
Turbines are inherently dangerous to run. Please read these instructions completely over
and over then read them over and over AGAIN. You must be entirely familiar with the
operation of this turbine before attempting to run this unit. It is strongly advised that if
this is a first time turbine that the user engage the help of a seasoned pilot or turbine
mechanic in order to help to familiarize the user with the operation and to minimize
potential risks involved. This entails risk to the engine and risk to yourself and any
bystanders.
SWIWIN USA/CRX will not assume any responsibility for any damages or injury to the user
or bystanders. Our responsibility is explicitly limited to the motor and to the internal
workings and ancillary supplies offered with the turbine.
SWIWIN USA/CRX advises ALL users (novice or pro) to test their motors in a test stand
before mounting them in a plane. The reason for this is to familiarize yourself with
SWIWIN motor operation and to ensure reliable operation before mounting the engine in
the plane.
If you have any questions, do not run the turbine. If
you are unsure about how to operate the unit, do not
run the turbine.
Safety First
Users need to be versed in model jet turbine operation. Purchaser
acknowledges the risks and dangers involved . Turbines are potentially
hazardous to operate and pose a risk to the user and any bystanders.
 Risk of expelled compressor blades (front
 Risk of expelled turbine blades (rear)
 Risk of Burns
 Risk of long range effect of inhalation of smoke from turbine
oil additives
 Risk of death or injury due to loss of control of a turbine or
turbine model
User accepts full responsibility for all risks including those to any bystanders.
Figure 1 Minimum Safe Distance

Pg. 6
User accepts responsibility and bares all risks associated with operation of SWIWIN/CRX turbine
engines.
Warning to Bystanders - User acknowledges the risk of injury or burns to bystanders during
start-up or while operating a turbine. User agrees to take all steps necessary to ensure that
all persons are situated a safe distance from the operations of the engine.
Please refer to figure 1. Always ensure, that all bystanders maintain a safe distance from the engine.
At least 10m (30ft) clear of the area to the side and rear of the engine, Turbines rarely catastrophically
malfunction but in the rare event of an issue, it is best to maintain a safe distance.
Fire extinguishers –It is absolutely crucial to have at least one CO2 extinguisher and a Class ABC
extinguisher on hand at all times. CO2 is the only recommended application for a motor fire. A dry
chemical extinguisher will work to extinguish a motor fire but the residue left behind from dry
chemical extinguishers does heavy damage to a running turbine. If a chemical extinguisher is used to
extinguish a running engine fire, the motor will need to be completely disassembled and cleaned.
The warranty is void if dry chemical extinguisher is ever used to extinguish a turbine fire.
Important Note: Please be sure to inspect all extinguishers each day that a turbine is being used.
There is nothing more disheartening than watching a plane burn because a fire extinguisher was not
operational when needed.
Failsafe -
Failsafe. Please read carefully on the notes on setting the failsafe on your radio to ensure
safe operation in event of interference or loss of signal.
Ear Protection –Turbines produce excessive Db levels of noise. Always use ear protection when
running the engine.
Burns - Exhaust gases are very hot (up to 1000°C/1800°F) and can cause burns to skin or damage to
objects close to it –keep exhausts clear of anything which is affected by such heat. The exhaust from
a turbine can and will burn grass and ignite dry brush.
Turbine Oil Toxicity - Turbine oil is poisonous. Keep it away from the mouth and eyes and from contact
with skin. Always store it in a marked container and out of reach to children.
Inhalation of Smoke from Turbine Exhaust –Smoke generated from burning turbine oil is a known
carcinogen. Prolonged and repeated exposure to turbine exhaust (1when using turbine oil) can pose a
health hazard.
Ground Assistants - Use a qualified ground assistant during all Start-Up procedures . Purchaser
agrees to use an assistant who is familiar with the operations of a micro turbine.
Keep assistants close and be sure that they understand their role before starting the engine. One
assistant should carry out the role of fireman. Ensure that they are aware of what to do in event of
1Turbine oil or Mobil DTE may be used for lubrication purposes.

Motor Setup
Introduction –For first time users and for first time use of any engine, it is strongly recommended that
the motor be placed into a test stand for the first time. I cannot count how many times, we have
gotten calls from customers that have worked tirelessly to install a motor in their plane only to
realize it had to come out and/or they experienced an issue on startup and caused damage to their
plane from an improper start. There is absolutely no reason for this. Please don’t disregard the
initial test process.
Mount the engine in a test stand that will minimally handle the full thrust of the engine. Weight the
table if needed. Do not do this indoors. Do route the exhaust outdoors if in a garage or into a pipe
that goes outdoors. Mount the ancillaries neatly where you can see them. Do not skimp on this
step. Note the orientation of the parts and the plumbing. Make sure the valve is off. Then work
on the electrical. It is difficult to mix up polarity with all of the enhancements to the wiring we
provide now but depending on how you are supplying main current, please observe correct polarity
when connecting to the ECU. If you mix up polarity on the main supply, the ecu will instantly be
destroyed. There is no warranty on a burnt ecu.

Pg. 13
1. Please refer Motor Setup above. Connect the motor festo fitting to a section of 4mm tubing
(included). Route the tubing to the filter then to the shut off as shown.
2. Connect the other end of the shutoff with 4mm tubing to the output of the pump.
3. Plumb the UAT as shown and per the UAT instructions (UAT is not included)
4. Plumb the Fuel tank per the manufacturer instructions noting orientation above.
5. Connect Input of fuel pump to UAT fuel out fitting
6. Double check your fittings
7. Use 20 gauge stainless wire to secure tubing to non-festo connections.
Pump Setup
Refer to plumbing for pumps below. Depending on the engine, you received a small pump (60) or a
large pump for 80 and up.
For 160, 170, 190 and above, fuel inlet to the pump is 6mm nylon tubing and 4mm from the pump the
engine. All motors are 4mm inlet.
Figure 11 Plumbing for pumps
Radio Setup and Radio Training –Study RC
Refer to Study RC below. It may take some getting used to the functions of the GSU. Note the signal
level changes as you raise stick and trim.
1. Highlight maximum on the GSU, raise the radio stick
and trim to max. Depress OK to lock in the new max
value.
2. Highlight idle on the GSU and lower stick to min and
trim to anything above minimum. Depress Ok to lock in
the idle value.
3. Highlight Minimum on GSU and lower the trim to
any value you wish to use as stop.
Note: when set properly, the turbine will go to cool
down when the signal value reaches the value you set as
stop.
Startup Operation
Prior to running the turbine walk around the aircraft or motor stand and make sure that all power and
data connections are placed properly.

Pg. 14
Note: First time motor use. Please be sure to prime the pump and remove all air from the lines before
attempting to start the engine.
1. Turn the fuel valve to the on position
2. Turn on power to the transmitter and receiver and observe GSU startup. The motor and GSU
will sync up with an audible signal.
3. If this is the first startup, use the test menu and locate “test pump” function.
4. Prime the lines with fuel using the test pump function. The fuel line to the motor can be placed
into a tank to circulate fuel then connected to the motor when primed. Failure to conduct this
exercise will cause the motor not to run.
Note: Some users report running the pump for a few minutes with fuel circulating to “break in”
the pump before running the engine for the first time.
5. With the throttle at minimum, raise the trim to idle and observe ECU status switches from
“stop”to “ready”.If the ECU does not transition to ready state, recheck the ECU to radio
connection and retrain if needed.
6. Raise the throttle stick to full then to min. This will initiate a start sequence.
7. The starter motor will begin to spin. The ECU will switch to ignition, then to preheat, then
to ramp.
Ignition - This the first start phase. There is a minimal flow of fuel (based on pump voltage you
select) to the plug. After a few seconds, observe pump energy on the GSU. You should hear
the burning of fuel. A sizzling can be heard. As heat increases, the engine will then transition to
preheat. View the transition on the screen. Temperature should be on a continuous rise.
Preheat –the motor increases rpm to the value set in startup –“preheat RPM”. This is
accompanied by a transition of fuel to the main jets. The amount of fuel to the plug and mains is
controlled by the gas value.
Fuelramp –After the engine EGT reaches 120 degrees (C), the engine enters the fuelramp stage.
As the motor begins to ramp, the pump begins to pump more and more aggressively. The rate
at which the engine increases speed is based on the value set for percentage fuel ramp and ramp
start values. Adjust pump start, ramp start and % ramp to fine tune the startup. Please note
that these values have no effect on the running state of the engine.
First time use - After the motor reaches idle speed the ECU will train to the motor. For first time
only use, the ECU may indicate “raise stick to high”. Raise the stick to full and allow the motor
time to reach full output. This might take a bit. Next, the ecu will indicate “lower stick”.
Respond by lowering the stick (not the trim) to minimum. After the motor reaches idle speed, the
ECU will transfer control to the user and switch to “running” status.
Shutdown Procedure
Always observe proper shutdown and cooling of the turbine. Failure to observe proper
shutdown by not properly cooling the unit will render damage and will void the warranty.
Shut down the turbine
1. Lower the stick to minimum
2. Lower trim to stop (this is the level defined in learn RC procedure). When the stick is at
minimum and as the trim is lowered to the threshold initially set, the motor will shut down
and initiate a cool down sequence by turning on the starter motor to the RPM setting found
in the “cooling” menu. Brushless starters turn continuous until 78 degrees is reached. For
brushed motors the cooling is intermittent. Turn off the fuel.

Pg. 15
3. Turn off power to the ECU and plane
4. Turn off power to your radio
EXPERT TIP: At any interval whether after shutdown or prior to startup, whenever the stick is
raised to max, the motor enters cool down mode and continues spinning at a rate defined in
the “cooling menu” until the stick is lowered back down. This provides a handy means to
initiate the starter without going to test mode. This feature works regardless of engine
temperature.

ECU
The SWIWIN ECU was designed from the ground up and is based on 32 bit microprocessor
functionality and designed specifically for Swiwin Turbines.
SWIWIN ECUs offers the following benefits:
Data Logging
Auto start
Automatic Restart
Color Screen visible in direct sunlight
Configurable thrust curve with very fast throttle response
User upgradeable off Swiwin servers (via internet)
ECU/Motor Electrical Connections
PLEASE READ - Do not exceed maximum voltages!
Manufacturer Recommended Battery for Main Turbine Power –3S LIPO
Recommended Logic voltage –connect to Rx throttle (5v nominal)
Maximum Voltage for Main Power
27.4V (2S) –18.5 (5S) (XT60)
Receiver voltage
Nominal 5V –Please follow manufacturer recommendations. The ECU will begin to exhibit erratic
operation as voltage to the ECU goes below 5 volts. Screen will fade as voltage approaches 4 volts.
Main power voltage：*Programmable Minimum - 14.5 volts
*Please refer to figure 2 to adjust minimum main voltage. Minimum voltage is programmable and
should be based on the source voltage.
High Altitudes –Altitude affects the startup of any jet engine. Since air is thinner at higher altitudes,
the engine that you receive might need to be tweaked to work in your area. CRX is at 982 FT ASL.
For areas at sea level there is no concern but for others where ASL might be at 4 or 5000 such as areas
in mountains, there are parameters that will need to be adjusted. The functions in this guide have a
