I have been using 2 HXT D9 G2 2200mAh 3S 20-32C, http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=2045 in my 500.

As you can see in the attached Eagle Tree graph the RPM drops significantly when the AMP draw peaks. Does this mean the batteries ain't good enough?

This log is from a flight with a 100-95-90-95-100 thr curve, but I see the same when I have used different curves. I use stock engine with 13T pinion.

Those packs look a little weak.
They would probably do Ok on a 12 tooth pinion at 100% throttle.
