Comparison RadioMaster TX12 Mark II M2 ELRS vs RadioMaster Boxer M2 ELRS

— For copters (FPV drones). Controllers for controlling unmanned aerial vehicles - quadcopters, multicopters and FPV drones (with first-person view). The entire functionality of the drone rests on the shoulders of the remote control: moving in the air, maneuvering, transmitting a video signal from the camera, etc. Quadcopter controllers typically have knobs, levers, or buttons that allow the pilot to control the drone's movement. In addition, the remote control can be equipped with various switches and controls for other functions (activating the camera, turning on the autopilot, and much more).

— For helicopters. Control equipment for RC helicopters. When choosing such a controller, preference should be given to multi-channel remote controls (see “Number of channels”) - this is important for flexible control of all movements of the helicopter in the air (acceleration, climb, flight direction, rolls, auxiliary functions for switching various model options) .

— For airplanes. Control controllers for aircraft models - airplanes, biplanes, flying wings. Such remote controls are assigned the functions of adjusting flight altitude, aircraft speed, changing flight direction using ailerons, flaps, etc. In advanced aircraft models, the controller can be used to control engine starting, landing gear extension and other advanced functions.

— For gliders. Controllers for controlling the flight functions of gliders - aircraft models with a large wingspan (it can be more than 2 times the length of the fuselage). Radio-controlled gliders are equipped with engines, but due to the characteristics of the wing, constant operation of the engine is not required for stable flight - it is supposed to be started and “switched off” from the remote control, as well as to control other aspects of the flight.

- For cars. Devices and devices used to control the movement of model cars, buggies, truggies, crawlers and other RC vehicles. The remote control for such self-propelled vehicles usually contains handles, levers or joysticks that control various aspects of the model's movement. The functionality of car controllers often includes control of speed, direction, braking and other additional functions (for example, turning on headlights or sound effects in some models).

— For special equipment. Remote controls for large and “heavy” special equipment using radio control. This category includes buses, trucks, tractors, excavators, cranes and other models. The specificity of such controllers is often tied to expanded functionality, because in addition to banal movements, it is important to take into account the special capabilities of special equipment - control of the operation of lifting mechanisms, buckets, bodies for transporting goods, etc.

— For boats. Controllers for radio-controlled water transport - boats, yachts, submarines, catamarans, jet skis. Remote controls for such models allow you to control the movement of the boat and additional functions such as turning on/off the camera, lighting or sound effects.

Rated power of the transmitter installed in the controller. This is an important parameter for ensuring reliable control of the RC model at a distance. The power of the transmitter is measured in milliwatts (mW), and the higher the number, the further the signal reaches and the more reliable control will be over long distances or in conditions of interference. In professional models of remote controls, the transmitter power can exceed 1000 mW (1 W).

The operating range of the transmitter in the control panel, in other words, is the maximum distance that the RC model can move away from the transmitter without losing control. The greater this distance, the more convenient it is to operate the car, but at the same time, powerful “long-range” transmitters have corresponding dimensions, weight and cost. In practice, the range may be less than stated - for example, due to the presence of obstacles in the signal path or due to weak batteries. Therefore, it is best to choose according to this parameter with some reserve.

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.

The presence of a card reader in the controller is a device for reading removable memory cards.

A card reader allows you to expand the standard memory capacity of your own drive, and in its absence, it will serve as the only option for storing data. At the same time, removable cards have a number of advantages: they are noticeably cheaper than built-in storage (in terms of per gigabyte of volume), and the capacity of such a card can be chosen at your discretion. Since card readers are available in many modern devices (laptops, smartphones, tablets, etc.), replaceable cards make it easier to exchange information with such devices.

— Cover/case. Case for storing and transporting the controller. Cases are called soft cases - they are designed mainly to protect against dirt. Cases are made of hard materials - they are more bulky, but they are able to protect the remote control from impacts and shocks.

— Protection of gimbals/sticks. Protective covers or casings that cover the controller's control elements (in particular, sticks) and prevent them from being accidentally pressed. Such devices will come in handy for safely storing and carrying the remote control.

— A set of springs for suspensions. These controller gimbal kits typically come with several different spring options, allowing you to select the appropriate control stiffness based on the user's individual preferences. This provides greater flexibility and the ability to customize the control panel to suit specific needs and conditions of use.

- Protective glass. Glass or transparent film to protect the remote control screen from scratches, dirt and mechanical damage. Protective glasses are tasked with keeping the controller display in good condition. This is especially important on models with touchscreens or color TFT panels, where scratches or damage can negatively affect the quality of the information displayed.
