    I have aircraft and first I use 7,2V 1800mA SANYO and standard motor and my
    fly time was around 15 to 20 minutes if I lucky. After I change to Litium
    Polymer 11.6V and 2000mA and brushles my flyingtime was at most 48 minutes
    and that when playing att ground not try go upp with some termike.
    I think my storry tell everything.
    But one warning it can start fire if you crach the aircraft or you make to
    much load to and is not posible to charging so many time like Nic or Nim.

    Best regards Peter

    I am impressed by the rapid improvement of NiMH batteries. I was told
    that Lipoly batteries are better for radio controlled aircraft. After
    doing a little research, I noticed they might be poorly designed and
    hazardous in the sizes required. But I like the voltage. What about
    using regular lithium batteries? The problem is still going to be
    regulation, charging and discharging, isn't it? Comments about any
    useful types are invited. Thank you.

    Li-based cells are intrinsically better for aircraft because they offer
    better weight/energy ratios.

    Also, if you mount them correctly, you can get a rocket powered aircraft
    briefly when they vent.

    The Li based cells that don't explode from, time to time, usually don't
    have as high of a mximum current. For short blasts of high current NiCad
    or NiMH batteries may be better.

    Are you using this for an electric powered RC model, or to power the
    receiver?

    At any rate, the LiIon batteries are getting popular for e-power, but
    they have issues (but then, gasoline has issues too, you just have to
    pay attention to them).

    That would be for the aircraft, not the controller/transmitter.
