Flight controllers 1S

A flight controller is the central part of any FPV drone, responsible for its stability and control. 1S models are specifically designed for miniature and lightweight quadcopters that operate on a single battery (1S). Our catalog features high-quality flight controllers from leading manufacturers: BETAFPV, Happymodel, and HGLRC.

What is a 1S flight controller and why do you need it

A flight controller for a quadcopter is a board with a microprocessor that processes pilot commands and sensor data to ensure stable flight. This system works as the brain of the drone, receiving signals from the remote control, analyzing position in space using a gyroscope and accelerometer, and sending appropriate commands to the motors. 1S controllers have the following features:

• Compact size, optimized for micro-drones – typically ranging from 16x16 mm to 25x25 mm, allowing installation even on the smallest frames weighing up to 30-40 grams
• Low power consumption for maximum flight time – specially designed for efficient operation at 3.7-4.35V, consuming minimal energy (usually 20-50 mA in standby mode), which is critical for micro-drones with limited battery capacity
• Compatibility with 1S batteries (3.7-4.35V) – featuring built-in voltage regulators, reverse polarity protection, overvoltage protection, and special connectors (PH2.0, BT2.0, GNB27) for connecting lithium-polymer 1S batteries
• Integrated components (regulators, receivers, video transmitters) – to save space and weight, manufacturers combine multiple devices on a single board, creating so-called AIO (All-In-One) solutions, where a flight controller, 4 speed regulators, a signal receiver, and even a video transmitter can be located on one board
• Support for popular firmware (Betaflight, INAV, Silverware) – modern 1S controllers come with pre-installed open-source firmware that allows fine-tuning of the drone's flight characteristics and updating software as new versions are released

Advantages of 1S flight controllers

The FPV controllers presented in our store have several important advantages:

Integration of multiple components

Most of our flight controllers for quadcopters are AIO (All-In-One) solutions that include:

• Flight control processor (F4/F7)
• Motor speed regulators
• Built-in receiver (often with ELRS support)
• Video transmitter (in some models)

High performance

1S flight controllers from BETAFPV, Happymodel, and HGLRC provide:

• Fast gyroscope data processing (up to 8 kHz)
• Support for modern communication protocols
• Stable operation in various conditions
• Ability to fine-tune flight characteristics

Popular 1S flight controller models

BETAFPV Matrix 1S HD - This model is an ideal solution for creating a compact HD drone. The controller is equipped with a built-in HD video transmitter and a powerful processor, ensuring smooth flight with miniature device dimensions and rich functionality.

Happymodel X12 PRO ELRS - This popular controller with an integrated ELRS receiver features exceptional connection reliability even at significant distances. The device guarantees minimal control latency and excellent stability during flight.

HGLRC SPECTER 10A ELRS - For larger 1S-based models, this powerful controller with 10A regulators is an excellent choice. It is characterized by extended configuration options, increased regulator power, and exceptional reliability even under extreme loads.

How to choose a 1S flight controller

When choosing a flight controller, pay attention to the following parameters:

• Size and weight – should match your drone frame
• Processor type – modern F4/F7 processors provide better performance
• Presence of an integrated receiver – simplifies assembly and saves space
• Connector types – check compatibility with your motors and other components
• Supported protocols – for example, ELRS for maximum range
