Why Not Use ISM band?
How come no one has thought of using ISM band radios at 2.4 Ghz. It provides a strong signal and ranges up to 3,000 feet. Radio problems seem to happen a lot at compition. Spektrum has come out with their "DSM" (Digital Spectrum Modulation) radios for rc cars and works awsome, also no easy to damage metal antenna.
"Because of the relatively low noise in the ISM band, and the noise immunity inherent in DSSM systems, Spektrum DSM is said to be free of "glitching" (momentary corrupted or missing signals which can cause erratic movement or loss of control). Additionally, the system "binds" each transmitter to its particular receiver, ensuring that no transmitter will interfere with other nearby Spektrum DSM systems."
also, i can see the radio being more compact and useing one of the I/O pins insted of a big heavy serial cable.
