Throttle Runaway?

I ran a static test of my quad in my basement - I used ceramic tiles laid across the landing skids to secure it to the ground while throttling it up with propellers attached. I had the flight mode set to Stabilize.

After arming the aircraft, I gently increased the throttle and the motors responded. But at some point, as I increased further, the motors suddenly spun up to a much higher level than I commanded, and they would not respond when I moved the stick to idle. I had to throw the arm/disarm switch in order to shut the motors down.

Has anyone experienced this sort of behavior? I’m afraid to take it out to the field for a test flight out of fear that it may suddenly go full throttle, and I won’t be able to control it without disarming it in flight.

Stabalize is a closed loop control loop.

By using the tiles you opened the control loop, no wonder it went crazy.

Just go outside and test it, you will be fine.

Many have. This misunderstanding has been producing posts for years. It rivals wrong motor order and direction posts.

Okay, when the weather improves and I’m feeling confident, I will take it out for a test flight. Thanks!
