I am running my ArduCopter without any form of remote control. Today, I attached the props for the first time and tried to takeoff using a "TAKEOFF" waypoint in auto mode.
The motors spun enough to almost lift the copter off the ground, but not quite enough. It wobbled a tiny bit as it struggled to get off of the ground, but never actually lifted off.
Any ideas on how to fix this?
As a sidenote, I never did get a chance to calibrate my ESCs. Could this be related? From the wiki, I seemed to gather the calibration is typically for use with your RC system, to get used to the throttle and such. If I'm not using RC, is there any reason (or even way) to calibrate my ESCs?
