And it was fly so nice...until it dropped out of the sky

I was doing an autotune today with a medium-sized quad today. Seem to track really nicely for pitch and roll, but after almost moving onto the yaw portion of the AT, it disarmed and fell to the ground. The autopilot tried to deploy the chute, just didn’t quite get opened in time lol! Any thoughts?

What indication do you have that it disarmed?

If the chute deploys, it disarms first. Unfortunately, the chute didn’t open. But there was no reason I can see for the chute to deploy… Unless the Cube interpreted all that rock roll going on in the AT as a good time to deploy. So weird.

Looks like it to me. I think there was thrust loss on Motor 2 initially, Motor 1 drops and then things go to hell as it returns to earth.

Also noticed motors 3 and 4 are hitting spin min constantly. These motors and props be too much lift, which is funny given how well it falls.

at 0.18 maybe not surprising.

Forgot to change that. I had to use larger motor and props.
