12 IMPORTANT UPDATES 

As the use of the 

JET CENTRAL 

motors increase, we find some important things to update 

the user. One every owner will receive a current update page as it is released. 

1. 

IMPORTANT

 Use the supplied hangar 9 fuel filter just between the fuel pump and 

the turb

ine, this will insure you don’t clog the oil flow reducer. If you don’t use this filter 

you can damage the motor by reducing the flow of fuel/oil to the rear bearing! 

2.  Make sure to bring the trim to the lowest position to start the auto cool on the motor! 

3. 

IMPORTANT!

 Use only 5 cell 6V packs on your receiver; this will insure proper 

operation of the turbine electronics. You can use a regulator if wished but we find 6V 
packs work just fine with today's radio equipment. Tests have proven that all turbine 
electronics can get glitches by lower 4.8 Volt packs running you radio system. 

4. 

If it’s cold outside, 8°C (45°F) or below, and you get a time out message this is due to 
the start gas flow not being enough, just leave your fill supply hooked up and open as 
you cycle the throttle to start. Then, once you get a pre-heat message or Ramp 
message, disconnect the fill bottle and let the engine finish the ramping just from the 
onboard gas tank. Just Gas Start. 

5.  If you experience any type of engine failure make sure to check the last power down 

cause and fix the issue. You do this by turning the receiver power switch off and on, 
wait until you get the main menu, then push and hold the menu down. The 

I.C.S.

 will 

tell you why the turbine was shut down and important parameters 

to verify. Don’t try to 

restart the turbine again until you have wrote parameters down for future reference, 
they will be reset after the next run. 

6.  Charge your batteries properly and make sure your packs are no less than 2 flights 

low. You can go more if y

ou wish, but it’s a good habit to re-charge after every second 

flight. 

7.  IT IS IMPORTANT IF YOU FLY ANOTHER BRAND OF TURBINE TO MAKE SURE 

YOU UNDERSTAND THE STARTING PROCEDURES OF THE JET CENTRAL 
I.C.S. ECU AND UNDERSTAND THE DIFFERANCE. 

Programming the transmitter when the HDT asks for stick up and trim up, place the trim all 
the way to the top; then when the HDT asks for stick low trim at idle place the trim only to the 
center during this learn feature. 

Follow the above steps and now if needed after your turbine is running you can use the 
seconded half of your trim movement to idle up your motor to create some residual thrust to 
help in taxing and for landing if wished.
