Quad Weight Distribution


#1

I’m experimenting with adding more batteries to my quad to extend flight time. I am considering either adding an additional 4s battery to the center of the quad, vs adding 4 1s batteries wired in series on the 4 arms of the quad. My immediate reaction is that putting more weight further from the center would mean more rotational inertia for the quad. The advantage is that not all of the weight would be stacked onto the center, sticking out from the top and the bottom. Any thoughts?

Apart from the extra hassle, having the weight on the arms would make the quadcopter slower to respond so I personally things its not a good idea.

Also if you are flying a FPV quad, the power to weight ratio is so high that the COG realy does not make much difference so I wouldnt worry about that.
