For those of you who are relatively new to the whole concept of model flying, the whole issue of whether to choose between 35MHz and 2.4GHz may not really seem much of an issue. However, there are a number of key differences between the two.
When put simply, they basically refer to the frequency at which the transmitter and receiver operate at in order to fly radio control helicopters.
The 35MHz frequency, which utilises crystals to determine its precise frequency, has been around now for many years. If you were using your copter in a field with other models together you would have to ensure the two frequencies did not clash or interference may cause a crash to happen.
With the more recent 2.4 GHz transmitter, once it is paired with the receiver, it is actually locked onto its own particular frequency. This eliminates the problems mentioned above as there is no risk of interference between numerous aircraft flying within the same area, all at the same time.
There are other differences between the two frequencies used by RC models. We will look more closely at these in the next article.
