Why are Nomadio radios better?

First, most radios are limited to a specific frequency, and that frequency is derived from a crystal. This is a big problem at races because there are only 30 or so frequencies to choose from. It is very common for racers to have their car "hijacked" by accident when someone in the pits accidentally transmits commands on the same frequency as their car Race organizers are forced to tabulate and organize frequencies before races, and it is common for racers to own six or seven sets of crystals to provide frequency choice in a race.

Second, because these analog radios are one-way, there is no flow of information back from the car. Users cannot tell how fast their car is going, when the batteries are running low, or if the motor is overheating. Cars that are powered by internal combustion engines (known as nitro cars) are very dependent on the temperature of the engine for top performance. At present, drivers can only check engine temperature at the beginning or end of a race, by disassembling the car and using an infrared temperature detector.

RC hobbyists need a radio system with the following features:

Provide two way communication so the car's condition is displayed on the controller
Ensure that nobody else can "hijack" his or her car during a race.
Eliminate fixed frequency crystals, and the need to purchase them in quantity
Add intelligence to their car for dynamic steering or anti-lock braking
Provide future expansion capability to add more servos or more information to report back
Capture race information for later analysis using a PC

These features are precisely what the Nomadio Systems provide, and at a price that is comparable to the top-end controllers that they grossly outperform.
