The Red-belly snake (Storeria occipitomaculata) is a relatively small snake that rarely exceeds 12 inches in length. It is native to North America, Mexico and Central America, and it is NOT venomous.
The electromagnetic frequency of a wave is defined as how many times the peak of this oscillation moves past a point each second. This has a major effect on the properties of the wave, including its energy.
The frequency of a controller / receiver basically equates to the number of times the signal completes one wave a second. The higher the frequency, the more electromagnetic waves a second and the higher the energy of the signal. On R/C vehicles, the frequency is generally 25-75MHz or 2.4GHz - a higher energy frequency.
