Thanks so much for all the info I really appreciate it.
I did end up buying the lipos for my micros some time ago from Hobby City. got 10 of them as the lipos that came with the su and the p-51 did not last long at all. I was a little skeptical because everything was so cheap, but I got the batteries yesterday with no issues. So I am really happy with Hobby City.
Thanks again for the info...It helps a lot...
