Really would like to know what most people do and why.
Second - there are not ANY advantages to running separate battery packs that I can think of. There are several con's however.
- One battery is not as capable and you fly a tad too long and you have one motor quit before the other
- Battery failure and one motor quits
- Different charge state of the battery is lessened with parallel
It is really about keeping both spinning.
