Of course a switch can be used for arming.

Please post your config file.

here you go,
its not that i cant arm , but when flm2 is selected , direct dead stop / where i dont have when yaw-l is used

Be sure you don't have some mixing between channel 5 (flight mode) and channel 8 (used for arming) in your radio.

Your second flight mode uses GPS Assist.

Have you configured GPS?

It may be a bug in that it should give a arming or GCS error to stop you from flying a non GPS mode with GPS Assist (when GPS is not set up and calibrated) like it already does for the obvious GPS modes.

Since the algorithm is INS13 i think the GPS is configured or he cannot arm at all.

gps enabled yes ,, but even if no gps setup still full drop
and gps is working have around 10+ sat's and i cant arm btw if it was bad.

also just tested basic

arm(1)-> idle spin (flm1) -> flm2 -> dead
arm(1) -> idle spin (flm1->arm/0->flm2) dead 
using arm yaw or any all oke

You should consider you are using Next, sometimes there is issues.

Please do a log file that shows the disarm while switching to Fm2.
May not need flying, just on ground.

 i only use next

i think i have found my problem ( wrong key setup wen looking a tx monitor)
seems that when flight mode is anything but 1 , that key will be 0

[Jhinta]

yes that was the problem, wrong tx setup
my tx has key setup per flight mode, i only had it for the first

So issue resolved
