No. No eagle tree. I have one but, I gave up on worrying about the details like that. I havent even touched it in years. As long as the pack delivers the punch and doesnt puff when I beat on it its a good pack to me.
As far as run time.... It depends on the track really. If its a tight track where you are picking through alot of technical stuff and you cant really lean on it then I get more run time, but if the traction is up and the track has room to let it run then I can blast through the mah. Same as anyone. The tracks around here tend to be on the large side so they do require some juice.
