This is an awesome thread and the OP gets the thumbs up in my book. I'd want the 500 to swing true 500mm blades as a next challenge. But much respect, the thing is awesome. Align used to make some 1100mah 6s packs. Too bad they discontinued them.

To the comments about efficiency. People really need to learn what efficiency means. It is the ratio of current consumed to power produced. So a power system could use a TON of current and still be efficient- all it has to do is make enough power to balance out the equation.

When you double the voltage like he did in this thread, you basically drop the current in half. So this helicopter is making a LOT more power and torque and using about half the current to do it. It is much more "efficient" than the 6s system was.

If you looked at his logs... the current consumed on average would be lower... and the power produced would be higher. The 6s system average current consumed would be higher and the power produced would be lower. That's the power of voltage- an electromotive force. And yea, it's more efficient.
