And this is correct however..\r\n\r\n**All other actions in Cleanflight that might cause a spin up come with a warning** (e.g. the motor page, setting oneshot etc.). This is even more dangerous, as it's not just arming and spinning at low-idle speeds (as with normal stick arming where throttle is naturally at zero), but you're now at the mercy of wherever the sticks of your transmitter are.\r\n\r\nReporting this as I had it happen to me in the field when (miss)using EZ-GUI. Obviously on the bench using Cleanflight I have props off, but not everyone follows this advice, and there is a danger here.\r\n\r\nNot sure the best way to prevent this - perhaps do not allow the user to save the Modes page if a save will result in ARM on.

However, poor and momentary lapse of judgement do occur. \r\n\r\nGenerally Cleanflight provides at least a cursory warning to a user when their actions are potentially dangerous, in the examples I provided. This action is arguably more dangerous and yet can be completely innocently triggered.\r\n"}}
