The failsafe set up procedures are on page 29 of the manual:

Setup failsafe mode and “Learn RC”. The updated ECU has the unique ability to shut-off your engine if you have a radio failure. This is accomplished by detecting that the signal from the receiver’s throttle output is either missing or outside the values that were learned during setup. YOU ARE REQUIRED TO USE THE FAILSAFE! This will not instantly shut off the engine. A timer is started when the failsafe condition occurs and the engine will immediately go to idle. After 3 seconds (2 seconds after V5.0A for AMA requirements as of March 1, 2004) the engine will then shut off. This 2 second timer is reset back to zero anytime a non-failsafe condition is met. Your R/C signal must be broken for at least 2 continuous seconds before the engine is shut off. The following is for PCM receivers only. Users of FM (PPM) receivers bypass the failsafe instructions and go to the ”Learn R/C” section in the manual. (FM Receivers are not allowed under AMA rules.) Setting the failsafe for JR PCM receivers The following procedures are for most radios like JR and Futaba. Call JetCat USA for failsafe setup procedures for Futaba 8U radios or other radio brands. If you look at the following servo travel graph, you can see how the ECU detects a failsafe condition. The dark gray bar is the transmitters throttle channel for low throttle, low throttle trim and full throttle set to 100% travel. This is the value that is set into the transmitter’s failsafe. The light gray bar is a reduced low throttle, low throttle trim travel and full throttle set to 75%. This is the value that will be taught into the ECU. If the throttle input to the ECU is between 75% for low throttle, low throttle trim and 75% for full throttle, then this would be within the normal range taught into the ECU and will operate normally. If a failsafe condition exists, the transmitter’s pre-programmed 100% low throttle, low throttle trim will be outputted by the receiver and this value would be outside of the ECU’s taught in range. The ECU will now automatically set the engine to idle (after the FailSafe delay) and start a programmable timer. The timer is set to 2 seconds by default. If the timer times out, the ECU will shut-off the engine. If at anytime during this countdown the receivers signal is reacquired, the ECU timer will be reset and the engine will go back to the speed the throttle stick is currently at. Low High throttle throttle Failsafe 100% low / 100% high throttle travel.ECU 75% low / 75% high throttle travel. Page 29/75
To accomplish this, you must execute the following steps. It is VITAL that these steps be preformed in this order for the failsafe feature to operate properly! Review your transmitter’s manual on how to set the failsafe. Examples are given for the JR 10X with S style receivers. YOU MUST PERFORM THESE STEPS! IMPORTANT: IF YOU CHANGE YOUR TRANSMITTERS FAILSAFE AGAIN IN THE FUTURE, YOU MUST REDUE THE FOLLOWING INSTRUCTIONS AGAIN. FOR TWO CHANNEL OPERATION: DO NOT SET THE AUX CHANNEL IN YOUR TRANSMITTER FOR FAILSAFE. KEEP IT IN HOLD MODE ONLY. THE AUX CHANNEL IS ALWAYS DESIGNED TO STOP THE ENGINE INSTANTLY IF COMMANDED TO DO SO. • First, set your transmitters travel parameter to 100% for low throttle and 100% for high throttle. On the JR 10X transmitter, use function 12 to access the throttle travel. • Set your transmitters failsafe for low throttle, low throttle trim. On the JR 10X transmitter use function 77 to access the failsafe. Enable the throttle channel for a failsafe (select 1 so the bar is in the top position ▀) and then set the throttle stick and throttle trim to their minimum positions. Save this minimum position by pressing STORE. • Return to the travel menu and now set the minimum and maximum throttle travel to 75%. • Now you must teach in these values into the ECU. Refer to ”Learn R/C” section in this manual for this procedure. You can verify the failsafe function in the default GSU screen. Default Display This symbol will appear when in failsafe. If you turn-off your transmitter, the default display will indicate a failsafe by displaying an . If you turn the transmitter back on, the will disappear. If the does not appear when you turn-off your transmitter, the fail-safe is not programmed properly! 21 0.0 6.9 OC: You can verify the failsafe parameters by accessing the RC Check Menu. Press and hold the Select Menu key on the GSU and by pressing the ► + key until the RC-Check Menu is displayed. Now release the Select Menu key. Time in Failsafe (seconds) If you press the ◄ - in the RC-Check Menu until you see FailSafeTime: the display will indicate the number of seconds the reciever was in failsafe. This is a total time for all the failsafe counts. If you turn-off your transmitter, it will increase every second. This is a great tool for diagnosing the quality of the RC systems RF link by checking this after each flight. FailSafeTime (s) :100.1 Page 30/75
Number of Failsafes If you press the ◄ - again you see Failsafe count: the display will indicate the number of times the receiver went into failsafe. If you turn-off and turn-on your transmitter, it will increase this count by one. This is a great tool for diagnosing the quality of the RC systems RF link by checking this after each flight. FailSafe Count :1 Refer to the Limits menu for the following parameters. Failsafe delay Setting for the period before the ECU will go into the Failsafe mode and reduce the throttle to the preset FailSafeRPM. After the FailSafeTimeOut below, the engine would then shut off. This maybe programmed from 0.1 to 20 seconds (Default = 0.1 seconds). Failsafe Delay :0.1 Failsafe timeout Setting for how long the turbine will run in a failsafe condition before the engine shuts off. This may be programmed from 0.1 to 20 seconds (Default = 2 seconds). FailSafeTimeOut :2.0 Failsafe RPM Setting for the RPM the engine will run at durring the FailSafeTimeOut. This maybe programmed from Minimum RPM to Maximum RPM (Default = Minimum RPM). FailSafeRPM :33000 If the engine is shutdown because of a failsafe, in the Info Menu the LAST-OffCond :FailSafe will be displayed. The Info Menu has selections for LastFailsafeCnt:0 and Last FailSafeTim:0.0. This is the number of times the ECU went into failsafe and the actual time period it was in failsafe during the last flight.
