    take a look at botmite.com - camera page. This is not suggestion: Maynard Hill flew his autopilot plane some 1800 miles across the Atlantic Ocean using satellite telemetry updates losing four planes dunking in the Atlantic Ocean before he clinched a landing in Ireland to take the record. I am pretty sure he called FAA and filed a NOTAM staying below 1,000 AGL. But you should have spotters and a well tested platform: flying and control.

    Lower frequencies penetrate further for the same power output of other frequencies. Lower the frequency the less information can be stored within it. Lower frequencies also propagate more easily allowing non-LOS in some cases.
    Common radio frequencies in use by modellers 27MHz, 35MHz, 50MHz, 900MHz, 1.2GHz, 2.4GHz, 5.8GHz (I'm sure I've missed a couple). Not all frequencies are legal in all countries though so check your own regulations to be sure.
    35MHz is widely touted by FPVers as a good choice and the only data being sent is the control so I would recommend it. Also this leaves plenty of frequencies for you to use for video, telemetry etc.

    Generally the lower the better,

    There are other consderations (available bandwidth, line of sight, interference rejection) but it's a safe rule of thumb.
