I have the 3DR 2014 DIY Quad kit, and am trying to autotune it - but my battery does not have the power to complete the process :/
I am flying with 3S Turnigy Nano-Tech 4000mAh and 5000mAh batteries and get about 5 - 6 minutes of flight time out of it.
I would like to move to 4S batteries.
Will that result in a longer flight time?
And what C rating?
I am flying stock DIY kit with 20Amp ESC's and 880kV motors.
