Well basically there seems to be two options:

    FM Transciever approach
requires modulation of data into audio channel plus demodulation on ground (both ways for control)
            cheap for long range
            some cheap ones support both long range and video

    Radio modem approach
            expensive for long range
expensive for decent bandwidth to tx video + teletry and rx control (optional)
            errrr... no soft modulation required

As for the power, it's too device-specific. Some use it correctly and some waste it horribly. Though for electric airframes this is an issue.

Well i guess i have decided... Now i just have to choose i nice set of 2 fm transcievers and a nice set of antennae. Anyone care to speak about their experiences?
