Fill the on board tanks through the UAT tank filling tube. Make sure the “fuel dot” is fitted after refueling. It
is important to check the “fuel dot” for a secure fit. If it leaks, the UAT can fill with air, causing the turbine to
shut down.
Prime the pump and system (Not needed for the RXi)
To prime the fuel pump and fuel lines (or for fuel pump test purposes), it is necessary to open the fuel
solenoid shutoff valve and run the fuel pump manually. For this purpose, use the Test–Functions Menu
selection, Fuel Pump Test (Purge Fuel). This test opens the fuel valve and acts as a speed control for
running the pump. Note: RX engines have internal solenoids so the valve function is irrelevant.
Before activating the purge pump mode, ALWAYS remove the fuel feed line
connected to the turbine.
Pump Test / Purge Fuel allows the fuel pump to operate without the turbine running.
However, if the fuel feed line is not removed from the turbine during this procedure; it will
become flooded with fuel. When this occurs, the next turbine start can become highly
combustible!
Use the select menu key and select the Test-Functions menu.
Press the Change Value/Item key to run the pump. If you want to change the voltage the pump runs at,
press either the ◄ - or ►+ while pressing the Change Value/Item key. It is best to lower the pump voltage
back down to the 0.5V default amount when finished.
Running the turbine for the first time
The Checklist
Before Running the Turbine
Charge ECU Battery. You must read and obey warnings on the LiPo/LiFePo battery pack.
Prepare CO2 fire extinguisher
Check fuel lines and filter. Make sure they are clean with no restrictions
Check that the fuel tank vent is unobstructed
Mix 5 % oil in fuel (i.e.: 1 quart per 5 gallons of kerosene)
Fill fuel tank(s). Make sure the main and header tanks are full
Turn on receiver switch
Place the model with nose into the wind
Activate brakes and start turbine
After Stopping the Turbine
Turn model into the wind. Activate brakes and stop turbine
During the cooling process the receiver switch can be shut off at any time. When the cooling
process is complete, the ECU will automatically shut off
After each flying session, defuel the tanks before storing.
WARNING!
In case of a mishap, fire extinguishers should be on hand at all times. JetCat recommends the
CO/2 variety. Powdered extinguishers will corrode the precision components inside the
turbine and void your warranty.
Remember when the Select Menu key is pressed and held, the ◄ - / ►+ keys are used to
select another menu. When a desired menu is reached, release the Select Menu key, and
your selection becomes the currently displayed menu.
