As the only way to remotely operate the EDU RC is now by a hobby radio, I imagine that FIRST had the EDU bot in mind as more of a platform for testing code that does not require input, ie Autonomous Mode. If they had intended the major use to be with a radio, I imagine they would have bundled one with the kit, so that we do not have to buy $100 worth of extra electronics.
Also, I found that most aircraft radios such as these:

also come in models for 75MHz. Does this make them acceptable for ground vehicles, of do aircraft use this frequency as well?
