Examine all Festo fittings,
nipples, clunk, filter, etc.
Check for fuel filter clogs.
Test the pump in manual mode

Clean O-ring and compressor
nut periodically, with cotton
swab and solvent.
EGT giving erratic

RPM readings.
Transmitter antenna too close

Keep the antenna away from the
model. It may cause false

Watchdog Failure
Static discharge reset the ECU. Do not mount 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 available from
electronic or hardware supply
stores.
Reason for Shut-Down
There are three ways to diagnose why the engine flamed out.
1. In the info menu the "LAST OFF-COND" variable will tell you why. For example,
low RPM, high temp, fail-safe etc.
This parameter is non-volatile and will be
available until the engine is run again.
2. With V4.0g and later ECU you can view the last 4 seconds of the flight before it
shut-down. This data is updated every 0.2 seconds. This allows you to see the
trend leading up to the shut-down. This mode is entered by pressing the "+" key
of the GSU while powering up the ECU. You can scroll through the data using
the (+ or -) keys and scroll forward and backward through time using the (info or
min/max) keys.
This parameter is non-volatile and will be available until the
engine is run again.
