Hi, I'm brand new here and also very new to RC vehicles so I appreciate any answers and patience.
I have a PX4 I'm using it in a 450 quad frame. I have installed firmware and set everything up from qgroundcontrol. Everything works, but when I arm the motors, they spin up fast enought that the quad takes off even with the throttle all the way down. I have calibrated everything and double checked my set up. I'm not sure what else I can do. This happens in both manual and auto level modes.
I have searched for hours to try to find an answer. There seems to be a parameter called MOT_SPIN_ARMED that can be adjusted, but I can not find it anywhere in the parameters in qgc. Can someone explains to me like I'm a 5 year old how to adjust this parameter using qgroundcontrol for Mac? Or perhaps if there's something else I should try first? I would actually prefer that the motors don't start to spin when armed, but if I have to live with that at least maybe I could fix the uncontrolled take off and disarm crash landing?
Thanks for your help.
