ok i am looking at getting some more battery packs. what i have now is a 8.4v 1100mah bat at about 5.4 oz. so my wing loding is around 9 oz. sq foot. that other two packs i'am looking at are 9.6v 750mah with would drop my wing loading to 8 oz. sq foot or a 9.6v 1050mah which would raise my wing loading to 9.75 oz. sq foot. my question is would i get about the same flight time with the 750 with a liter wing loading or a 1050 with the heaver wing loading. i think that the lighter one would be better but i am unsure.
