Hi Gang,
Thanks for the replies. So the current reduction is as dramatic as I had thought!

Of course, there is a limit as to how small we can make our flight packs: both for cell resistance /regulator dropout reasons, and because one binding servo will still pull the same high current. We probably need enough to withstand a full flight with a near stalled servo. Provided you do a voltage check after each flight, that should prevent an unnecessary disaster.

later,
Dean
