Comparison RadioMaster Zorro M2 ELRS vs Jumper T-Pro V2 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.

The presence of a display controller in the design and the type of installed matrix.

The screen in remote controls for RC models can play different roles. Thus, it is possible to display a picture from the camera in real time on a color display, and service parameters are often superimposed on top of it (for example, flight altitude, speed, remaining battery charge level, all sorts of service notifications, etc.). Monochrome screens are usually assigned other tasks - first of all, they are responsible for tracking telemetry (for more details, see the corresponding paragraph).

It is customary to equip advanced controllers for RC models with a display. Simple remote controls are often presented without a display. And according to the types of matrices, there are the following screen options in controllers:

- OLED. In the context of control controllers, OLED screens usually mean the simplest solutions with a black backing and white symbols for displaying settings and/or various service information. Such displays are based on organic light-emitting diodes, and their key advantage is the ability to easily read the displayed information in poor ambient lighting.

- LCD. As a rule, these are the simplest monochrome screens - either segmented to display a limited set of characters, or based on a single-color...LCD matrix, suitable for text and basic graphic information. LCD screens provide additional convenience: they can display various important data, for example, the flight altitude of a conventional quadcopter, the speed of movement of the RC machine, the signal level, the remaining battery charge, notifications of problems, etc.

- TFT. A TFT display means a screen consisting not of segments, but of full pixels and suitable for displaying various types of data: graphic symbols, images, and even streaming video from an installed camera. TFT screens provide the most extensive visualization of settings; they are used in controllers for controlling drones and other RC models in FPV (First Person View) mode.

Display diagonal size in inches. The larger the display, the more accurate and easier to read the information displayed on it, the better the video stream can be seen on the screen in real time. On the other hand, a display that is too large entails an increase in the size and cost of the controller. In remote controls with the ability to display only service parameters, the screen size is usually from 1 to 3 inches, in copies with full color matrices and support for broadcasting a video stream - about 5 - 7 inches diagonally.

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 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 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.
