Well I got four more flights on it today and it just seems like one side of the two tanks always seems to have a little bit more fuel than the other one I take it apart I can't tell any difference between the two I'm not worried about it anymore got a guy who's building a third tank for me so I can add some capacity and I'll just have the two tanks Feed into that one large tank then to the U a T I think that'll take care of my issue
