here you go
http://wireless.fcc.gov/prs/radcntrl.html. read my quote from fcc Which R/C channels may I use?
"R/C Rule 7 lists 50 channels in the 72-73 MHz VHF range that may only be used to operate model aircraft devices and 30 channels in the 75.4-76.0 MHz VHF range that may only be used to operate model surface craft devices. You must stop such transmissions, however, if they interfere with authorized radio operations in those VHF ranges or with broadcast TV reception on channels 4 or 5. R/C Rule 7 also lists HF channels at 26.995, 27.045, 27.095, 27.145, 27.195, and 27.244 MHz that may be used to operate any kind of device including model aircraft and surface craft devices. R/C channels are not afforded any protection from interference due to the operation of fixed and mobile stations in other services assigned to the same or adjacent frequencies.
What is a "model"?
A model aircraft device is any small imitation of an aircraft. A model surface craft device is any small imitation of a boat, car or vehicle for carrying people or objects, except aircraft. "
now if only hobbico or tomy took advantage of all these frequencies. I need to reaseach this more but i got to go. so i will get back on this later.
