Hello,
How can i set failsafe to cut all energy when lose signal from transmitter? I really want to cut energy instead throttle at zero because on my setup my motors still spin when throttle is at 0.

Thank you

here the setup..
try the throttle value -100

It's all in the system tab. The picture from the above reply.  Set throttle to -100 and if you switch arm, set that to -100 also. Then SAVE at the top with the red arrow. I forget which one. Just hover over and it will pop up and tell you. But save and quick test with props off and your GTG. Super easy

I'm not sure that setting the throttle to -100 will help in all cases (always stabilize when armed, motors set to run at zero throttle).

I always set up my RC receiver to stop sending pulses when the transmitter is switched off, then just leave the default FC failsafe which is to stop all motors if the RC receiver stops sending pulses to the FC.

I haven't researched it in a while, I think this requires that your Configuration->Outputs (ESC inputs) be set so that "Min" stops the motors.

Of course the final thing is to do a simple test.  Set throttle so motors are running slowly on the ground; switch transmitter off.  Motors should stop.

I had to set -100 for my arm and throttle. Because it will keep the motors at idle with and x4r set to no pulses. I've tested extensively. It works. One I have set to no pulses and the other two I set the throttle and arm switch in the RX to switch off and go to -100. But I had to set the failsafe on the cc3d to -100 for throttle and arm

The default for all three of my copters running 15.09 were throttle -1. Which kept them ideling. I know I'm right I just went through a whole big deal with this. And had to prove my failsafe. -100 on throttle and arm so it defietly stops everything.
