I have build a quadcopter (Alien 560 Frame) with APM 2.6 and Firmware 3.2.
In the last week, I fly the copter with a 3S Lipo with 4000mah. The copter fly very stable and fine.
Yesterday, I have changed the Lipo to 4S with 5800mah. This weighs more.
The copter starts easy and fly stable, but the motors regulate up and down.
(The Motors and the ESCs can work with 4S).
Do I need to adjust by Hand?
Or can I use autotune?
At the moment I do not know if it’s good to fly the copter with Up and Down the motors …
Motor: AX-2810Q (750) 388W
