Hi everyone.

I’m trying to vent the drone without a joustick.

First, I send MAV_CMD_COMPONENT_ARM_DISARM command, and drone looks like arm in mission planner, then i send MAV_CMD_NAV_TAKEOFF command, and nothings happen.

Do you have a suggestion about this?

In which flight mode are you doing it? And please update to ArduCopter 4.1.5.
