Quote from: teslahed on Thursday,February 28, 2013, 10:16:37 Surprisingly not - i haven';t even retuned the PIDs, although i probably should - i might be able to get slightly smoother video if i lower my P on roll and pitch by 0.2 or so.
Quote from: Biffa on Thursday,February 28, 2013, 10:29:14 That is surprising, you would have thought with the weight on the top it would be fighting to keep upright all the time and stop tipping over. I wonder if the motors are working harder to keep it stable with the Gopro on top as well as coping with the extra payload.Didn';t sound over stressed though.
Quote from: teslahed on Thursday,February 28, 2013, 10:52:08 I would like to know more about the theory here. Because the way a quadcopter balances is a bit like an inverted pendulum (like balancing a broomstick on your finger). If you';ve ever balanced a broomstick you';ll know that the longer the stick and the higher the Centre of Gravity, the easier it is to balance.
