Recently, I received the first part for this project, a Crossfire radio system (thank you ECE depot at the U of M!). This is a long range radio link with up and down telemetry. This radio, unlike normal RC links (2.4GHz), operates on 900MHz (@ up to 2W, but that isn't legal even with a license). This band is classified as UHF. To operate in this band, you need an amateur radio license, specifically a technician class license.
Getting a HAM License is not the easiest, but definitely not the hardest. There is a ton of study materials out there. One of the ones I've liked so far is this one:

Fairly straightforward language with plenty of sample questions in it. Another great place for finding questions is here:
This has the actual bank of test questions.
I personally have not taken the test yet, but I plan to in about a week or two. Until then, I will be starting airframe design, based on the Talon style frame.

Upon further research, this radio is authorized by the FCC and therefore can operate without a license, although it is still recommended to get one, especially if using FPV
