Well I finally made my first flight without the buddy box last week end and brought my plane home all in one piece. I was wondering if anyone can give me an idea of how long I can fly on a full tank of fuel. I have a Hobbico Hobbi Star with a OS 65LA. I realize it depends on how hard I am flying the plane. Say for the most part I was flying about 3/4 throttle. Also whats the best way to keep up with time I can fly? I have the Futaba 6EXAP but it doesn't any timers on it that I can see. DO any transmitters have timers on them?

Also I am fixen to purchase a park zone T-28D BNF. I have a DX5e I was planning on using with it. My instructor doesn't like the DX5e transmitter for some reason. Any one have any feed back on using this transmitter with this plane?

Any help would be greatly appreciated.
