Helping a friend set up P70 with ECU version 6.0 for fail safe. We dont have any instructions so we are sort of winging it. Neither of us has much Jet Cat experience. I tried to do it the way my other egines are done but it didnt work. I set travel to 125 and then did the radio bind to set fail safe. Then went back set travel to 100 and did rebind. I think some where in there I was supposed to do a reteach of the ECU.

Can someone give me a step by step list of how to get the fail safe correctly set.

For my v10 JCs you bind the Rxer at 100%. Then set the travel to 50% and then do the RC learn.

You're close. Attached is a JetCat manual.

You need to decide whether to use the Aux Channel, most of us don't and typically use single channel mode.

Look that up and do as you want. I do the following for failsafe & throttle range:

Set Low Throttle end point to -150% and bind. Reset Low Throttle end point to -100% & High Throttle to +100% and bind again.

Do a Learn RC. On the GSU, hold Select Menu & power on. Hold the button until it says release to Learn RC.

Set trim low & throttle low and press the Select Menu button.
Set trim high & throttle low and press the Select Menu button
Set trim high & throttle high and press the Select menu button

I forgot to mention we are using single channel set up. Thanks Thud driver. I was going to try 150 % for my next try but it is good to get confirmation that it is the right thing to do. I will give this a try in the morning. I sure appreciate the help.

I don't use Spektrum anymore so I forgot that you shouldn't do the second bind the way I said above. Every time you bind, you need to set low throttle back to -150% to keep the correct failsafe. Afterwards reset to -100% without rebinding for proper operation.

To set up the failsafe on your p-70 with the v6.0 ECU. You want to bind the airplane with the turbine throttle travels settings at -100/+100. Then learn the ECU at -50/+50 and leave the settings at this. this was standard for both JR and Spektrum radios using the single channel settings. Then if you do any other adjustments to your set-up you just have to remember to bind the system with the throttle at -100/+100 and after you do a bind just reset the values back to -50/+50 and the ECU will retain the fail safe settings.

Is there a difference between ECU Version 6 and Version 10? Greg is correct for Version 10.

Binding throttle travel adjust at -150 and then at -100 simply erases the first -150 bind and resets the setting to 100. Just set throttle travel adjust at -100 and +100 and bind once. Then do the RC Learn with the throttle travel adjust at + and - 50%. Once you have done the RC Learn, the ECU sees the bands of travel below + and - 50 by using the throttle trim. Trim below -50% = off. Trim above +50% = on.

Failsafe is set in V 10 by using the GSU to select the Failsafe setting - Off or On. Then in another menu setting the related timing can be adjusted. However, the default failsafe settings should be good, unless someone changed them. Generally speaking, this is how it is addressed in V10. I am not sure how it is done in V 6.

Len,

What i have described is how i was told to do it for versions 4.0,5.0,and 6.0. I have never owend a jet cat with a v10.0 ECU.

According the the attached V6 manual, the RC learn settings on the V6 ECU is +75% and -75%. Other than those RC Learn settings everything looks pretty much the same as a V10. The initial bind is still at +100 and -100.

That was back before 2.4 came out then when that happened it was changed to-50/+50.

You can do it the way the manual says if you want, but I've done thousands of flights with it set at -150% and +/- 100%. It's all about getting the failsafe setting sufficiently far away from the normal operating range. Just set -150% in the Tx (for those that work that way) or bind at -150% and then set +/- 100% after. Works fine, 2.4, 72, whatever.
