[QUOTE="suprPHREAK, post: 32140, member: 1505"] The cells are run in series in order to give the volts needed to run everything. A 3S battery (which the Spark has) is ~12V, if you took away one or two, it would drop to 8v and 4v respectively. You could probably get away with smaller cells, but then you would need a higher C battery in order to match the output. You are right there isn't much to shave off. Suggstions I would have all rely on the body. Punch holes in the arms, the body, the top lid, the battery casing. But even then, probably just a few grams, not sure it would do much. Modding to a smaller battery for very short flights might be your best bet. [/QUOTE]
