Scott, I'd like to see more data before coming to any conclusions. If the packs consistently perform like this then I'd say #1 is really good and the others not bad. I don't like the fact that they aren't matched to each other. I'd imagine that you can really tell the difference in flight requiring different throttle settings. To me, consistency is very important.

Are you still using the Spin 99? How is the start up? Where do you set the acceleration? I've never been happy with mine.
