RC Helicopters 2.4 GHz Radio System

Until lately, frequency security was a major concern for anybody flying RC airplanes or helicopters, but with two.4 GHz radios that is no longer an issue. Given the added advantages of faster response and longer flight time and battery life, anyone new to flying RC airplanes ought to undoubtedly contemplate a two.four GHz system.

With conventional narrowband sets, a separate frequency is necessary to send data from the transmitter (TX) towards the receiver (RX) and then on towards the servos. If pilots B and C are flying RC airplanes on the same frequency as pilot A, they'll interfer with A's signal and most likely cause him to crash.

Spread spectrum technologies works differently, utilizing a wider band of frequencies and "spreading" the signal over that wider location to eliminate interference from narrowband sets or other 2.4 GHz radios.

There are two primary forms of spread spectrum systems, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS). DSSS radios send data more than a wide range of frequencies but remain within a fixed component of the 2.4 GHz band, while FHSS systems operate on a narrower band inside the 2.4 range, jumping hundreds of occasions a second to distinct frequencies. Spektrum and JR radio systems use DSSS technologies, Futaba and Airtronics two.4 GHz sets employ FHSS.

Each methods of signal transmission carry out equally well in blocking interference. Both also use less current than narrowband sets, meaning longer flight times and extended life for your batteries.

Several RC pilots nonetheless like their narrowband radios, but 2.4 makes achievable flying RC airplanes without fear of interference. If you're just coming towards the hobby, or thinking about upgrading your old radio sysytem, spread spectrum 2.four GHz will be the approach to go!
