Comparison RadioMaster Pocket 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.

— ...href="/en/list/1590/pr-51699/">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 option to connect an external transmitter to the controller via micro or nano connectors allows for expanded functionality in managing RC models by supporting various communication protocols (see the relevant paragraph). For example, the default remote control operates on the TBS Crossfire protocol, while using an external transmitter allows for operation on the ELRS protocol.

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.

One of the options for implementing feedback. Vibration is the controller’s reaction to certain events occurring with the RC model. For example, it may indicate that the permissible speed or altitude limit has been exceeded, signal a strong headwind or low batteries, etc. The remote control vibrates to inform the operator about important events that should not be overlooked.

Audio output for connecting wired headphones. The headphone output in the design of remote controls is usually represented by a classic mini-Jack connector (3.5 mm).

This interface is used to listen to sound signals and voice notifications directly through headphones. This may be important for providing privacy (without attracting attention from others), better sound insulation from external noise, making commands more clearly audible, etc.

The ability to use the remote control as a Bluetooth simulator - to control virtual RC models and improve skills in mobile simulators. Using appropriate software for a smartphone or tablet, the controller can be used to simulate the real behavior of RC equipment without the need to go to the field or site.

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.
