What to do if my JetCat P120 Engine turbine doesn't ignite?
If your JetCat Engine turbine doesn't ignite, check the starting gas system for leaks and poor connections. Ensure the starting gas tank is full and consider flying in warmer conditions. Adjust the glow plug voltage to ensure it glows bright red. If the glow plug is defective, replace it. Make sure the glow plug element is extracted by at least 1/8 inch (two coils).
What to do if the JetCat Engine starting process fails?
If the JetCat Engine starting process fails, wait until the Cool Down sequence is finished (the green OK LED will stop blinking). Charge the battery and check the ECU’s battery connection. Replace the defective glow plug if the red Pump running LED blinks. Check the three-conductor cable for the starter motor and glow plug for proper connection from the ECU to the turbine.
Why does my JetCat P120 Engine turbine ignite, but the start process is discontinued?
If your JetCat Engine turbine ignites but the start process is discontinued, it could be due to air in the fuel feed lines, the fuel pump not running, or the starting gas tank being nearly empty. Examine all Festo fittings, nipples, clunk, and filter for air leaks in the fuel system. Check for fuel filter clogs. Test the pump in manual mode to ensure it runs when the red Pump running LED illuminates. Fill the starting gas tank.
Why does the JetCat P120 Engine turbine quit with Watchdog Failure?
If the JetCat Engine turbine quits with a Watchdog Failure, it may be because static discharge reset the ECU. Do not mount the ECU directly to the fiberglass body of the plane. Use a plywood mount with a layer of foam tape and Velcro between the body and the ECU. If the plane has a glossy finish and the failure happened directly after the wheels left the ground, spray the tires with an anti-static spray.
How to clean a JetCat P120 starter unit that slips and makes noise?
To address a JetCat Engine starter unit that slips and makes noise, periodically clean the O-ring and compressor nut with a cotton swab and solvent to remove dust and oil sediment.
Why doesn't the JetCat Engine ECU follow full commands from the throttle stick?
If the JetCat Engine ECU doesn't follow full commands from the throttle stick, it may be due to a programming alteration in the R/C transmitter. Check alignment with the RC-Check menu and re-align the ECU to the R/C system.
Why is my JetCat P120 Engine EGT giving erratic temperature or RPM readings?
If your JetCat Engine EGT is giving erratic temperature or RPM readings, the transmitter antenna may be too close to the model. Keep the antenna away from the model, as it may cause false readings.
