RC Switch does arm but NOT DISARM

Hello together,

I am new to ArduRover and i was fighting through setup yesterday, things start working but I am having a problem with RC switch arming. I can arm the rover with the switch but i can not disarm it.

RC Inputs are calibrated.
I have attached my parameters. the message log does not mention anything. I am using Manual Mode at the moment.

Hardware is Pixhawk 1M with newest firmware, Taranis x9d.

Thanks for your help!

RC5_MIN,1494 might be the reason, it’s probably not low enough to disarm.

Thanks for the tip, i switched to a full scale channel, which was working.

I was assuming the threshold is somewhere between calibrated min/max.
