Aug 18, 2014 at 21:39 comment added Gustav Thanks! Doing that distinction between those two cases makes it much more clear. You did not write that in your answer.
Aug 18, 2014 at 19:52 comment added David Cary @Gustav: Have you considered maybe looking at Fig. 1 and the last section of the paper by Andres that I linked? When (a) optimizing for absolute maximum flight time, then yes, the weight of the batteries should be roughly two times the total weight of everything else combined. However, (b) many other characteristics -- time to get up to altitude, responsiveness, avoiding stall, etc. -- work better with less battery weight, so a better rule of thumb is batteries roughly the same (one times) the weight of everything else combined. How can I say this more clearly?
Aug 18, 2014 at 17:19 comment added Gustav This confuses me, weight of the batteries is twice as much as the weight of everything else. Does not that mean that the batteries should be 2/3 of the vessel?
