Compatibility
Compatibility of the controller with specific RC models. For many popular models, their own specialized remote controls are produced, which are initially tailored to the characteristics of a particular model. However, it is often possible to replace the “native” controller with a third-party one - many models of this type are produced with compatibility for a certain list of RC equipment. Before purchasing, it makes sense to check compatibility to avoid unpleasant surprises.
Controls
The total number of controls in the remote control directly depends on the design, manufacturer, model and, most importantly, the purpose of the controller. This paragraph specifies all switches, buttons, sticks, sliders, scroll wheels and other elements used to control the RC model.
Operating time
Time of continuous operation of the controller without recharging the battery or replacing batteries. When choosing based on this indicator, it is worth considering that it is quite approximate. In practice, operating time strongly depends on the intensity of use of the remote control, and in models powered by replaceable batteries, also on the quality of these elements. Actual autonomy can often be less, and sometimes even more, than declared. However, different models of controllers can be compared based on the operating time on one full charge given in the specifications.
