Well that's a whole different ballgame. It wouldn't hurt to possibly get bigger batteries (more ampere) and kind of chew up some of that balancing. besides you can never have to much battery. Then whatever is left over then add weight. Of course 3/4 lbs. to that bird will make little difference. I just hate adding weight, I like to find other useful ways of adding weight, possibly two battery packs. Weights sometime tend to come loose.
