The TrackStar Epic Fail Safe detects low RX voltage, loss of radio signal or interference and automatically applies the brake servo to prevent a runaway model. It can also work with other model types by shutting down the throttle servo.
Use this handy device to prevent having your own costly "Epic Fail" when running your model!

I received today the Epic fail safe, but until now it is being a EPIC FAIL :(
I'am trying to use this fail safe with a CRIOS AIO board. After note that the S, ,- wires are wrong and switched to the correct order, the Led green and red stay blinking, two led's in same time. When i turn off my TX, the green led turn off and seems that the fail safe is activated (all ok until now), but with transmitter on and the green and red led's blinking in the same time, the throttle signal that arrives to my CRIUS AIO is constantly glitching, between the TX actual signal and the Fail safe signal (920pwm, I thing). I'm doing some mistake here? Why the 2 led's still always flashing ?
Hi, I am currently using the stock 9x with my Naza FC. The stock rx that came with the 9x dosen't support failsafe. So instead of buying the frSky TX module and Rx, do you think I can use this little unit?
If I use it on the flight control channel of the Naza, do you think I can use it to trigger the failsafe algorith when the radio signal is lost?
Ok I received the EPIC Fail safe unit from Hobbyking.
And I can report that it works! I have the U channel of the NAZA (flight mode) plugged to channel 6 on the Turnigy receiver. So I just unplugged the servo from the receiver, plugged it in the failsafe unit, and plugged the fail safe unit to the Naza U channel. I programmed my 3 way switch in order to trigger failsafe as the down position. Now, to set the failsafe unit, I put the switch in the fail safe position, and I press the SET button on the failsafe unit. 3 flashes tells me that the setting have been saved.
Now, the failsafe unit detect the lost of connection (out of range or powr off) and send this impulse to the naza.
I can now put back the settings of my 3 way switch to gps - atti manual since the setting of the unit is done.
So for 4$ you can get the failsafe to the stock Turnigy 9X system.
If the fail safe unit is plugged in the throttle channel, you can program it to do exactly that. If you use it with a FC like me, and you plug it in the flight mode channel, then no, the throttle signal will stay at the last value received before loosing signal. But for failsafe with a Flight controller like the Naza, it is not needed. But if you absolutly want the throttle signal to drop to 0 in that specific application, you can use 2 failsafe unit, one in the throttle channel, one in the fligth mode channel.
A must have device for all the nitro powered things around. If your servo runs out of power it will center so the motor will receive half throttle. Not a good thing! This will protect from this situation. Should be used in combination with a proper failsafe setting on the receiver. This only works when the power of the receiver runs out. Not for out of range.
