I'm not sure i'm doing good..
I 'm flying with an apm 2.5, rx frsky, tx turnigy 9x.
I saw the video of Mark Harrison on youtube ( https://www.youtube.com/watch?v=r7B0Sfyb6Uo ) explaining how to setup your failsafe setup on your frsky. I did it too..It workds ! nice !
In the manual of the apm 2.5,, the failsafe is explained of an other way : https://code.google.com/p/arducopter/wiki/AC2_Failsafe?wl=en
Do i have to make the setup of the apm 2.5 like explained in the manual if i already follow the instruction of Mark Harrission (seup on the RX) ?
