Just wondering if it would be possible, and advantageous to hook two stock batteries in parralel. Voltage stays the same, but wouldn't you get 300mah and a much longer flight time? With guys making changes and stuffing in..or hanging under...some bigger batteries...i can see two 'stock' S107 batteries fitting inside my soon to be modified S107G to a 'gunship'
With the slight bit of added weight of the armament and other 'goodies' and new bodywork, I can see running the throttle a bit higher to maintain altitude and hover, and as a result, lessen my flight time on just one stock battery.
any thoughts? or better to just sling a biggie between the skids?
Well, the thing with that is, you have the same voltage (V is constant over parallel circuts) but the current would be doubled, and I'm not sure what that would do to the circuts. Now, there's a few people who have done things with putting two batteries in, and have flown alright.
That said, well, the people who have tried this, from what they've posted, have said that the s107 just can't lift the weight of two batteries. You could put a 300 mAh battery in it, and have less weight, but back then the one guy (I think it was BVC or JM Bishop) did extensive testing on the batteries, he found that somewhere between a 220 and 250 mah battery is the best place, because at 250 mAh, the heli has to produce so much more lift that it can't sustain as long of a flight. (which is also not ideal because that wears out the motors very badly and gives it a lot more mass for when it crashes, causing more damage in a crash)
