After a bas experience with an Hexa loss control, I decided to setup my Failsafe function on my MP32.
I have a Jeti RMK2 PPMSUM receiver with a Futaba FF9 2.4ghz Jeti module.
I used my Jeti Box Mini to execute the process.
I also used a WIKI link about Mikrokopter.

Follow all the steps on the scheme and you'll get the wanted result.
I made setup only on the channel 3 (throttle) but you can setup every channel if you want.
Step 15 is very important for setting the right value for your model. I held my model by hand I tried to power off my transmitter to see the failsafe behaviour.
For a safe process, it is better to execute test without props !
