http://sujan.hallikainen.org/FCC/FccRules/2008/95/603/ states "(b) Each
R/C transmitter (a transmitter that operates or is intended to operate at
a station authorized in the R/C) must be certificated, except one that 
transmits  only  in  the 26.27 MHz frequency band and is crystal
controlled (where the transmitted frequency is established by a crystal (a
quartz piezo-electric element)).

The list of  R/C frequencies is listed at
http://sujan.hallikainen.org/FCC/FccRules/2008/95/623/ .

http://sujan.hallikainen.org/FCC/FccRules/2008/95/631/ states "(b) An R/C
transmitter may transmit any appropriate non-voice emission which meets
the emission limitations of  Sec. 95.633."

http://sujan.hallikainen.org/FCC/FccRules/2008/95/633/ states "(b) The
authorized bandwidth for any emission type transmitted by an R/C
transmitter is 8 kHz."

http://sujan.hallikainen.org/FCC/FccRules/2008/95/639/ states "(b) No R/C
transmitter, under any condition of modulation, shall exceed a carrier
power or peak envelope TP (single-sideband only) of:
   (1) 4 W in the 26–27 MHz frequency band, except on channel frequency
27.255 MHz;
   (2) 25 W on channel frequency 27.255 MHz;
   (3) 0.75 W in the 72.76 MHz frequency band.
