QUAD with Hobbywing x11plus motor oscillating in Loiter mode

I want to increase the flight speed of a 40 kilogram drone to 100 kilometers per hour, but I am currently facing serious problems and need everyone’s help - ArduCopter / Copter 4.5 - ArduPilot Discourse

You can consider copying my settings. Although I am still experiencing some issues, my basic settings have been in use for 2 years and are very secure. The problem I encountered was due to a recent change in my blade design, which only occurred when the speed exceeded 20 meters.
You can consider using two TX150 plugs or QS8 QS9 QS10 plugs, both of which can be used safely. Because this configuration flies to 70 yards and the current is less than 200A
