Just recieved my Phoenix simulator today and working great. The problem is after a short 40 minutes my fully charged battery went dead and now it will take 18 hrs to fully charge it up, I am using an Hitec Optic 6. So my question is this is there anyway I can use my simulator and not have to quit after such a short time because my battery went dead. Getting more batteries and having to connect and disconnect seems like a hassle. Thanks, Nikolai
