Quadcopter Mobula6 1S Race ELRS 2.4G — a small and lightweight FPV drone

The Mobula6 1S Race ELRS 2.4G — is a compact and ultralight FPV quadcopter from the Happymodel brand, designed for flight training and freestyle in confined spaces. This mini-drone operates on the ExpressLRS 2.4G remote control protocol, ensuring minimal communication latency, high data transfer speed, and reliability during aggressive maneuvers. The Race version is equipped with powerful SE 0802 KV25000 brushless motors, which, combined with its very low weight, provides high maneuverability and quick response during tricks.

Key advantages at a glance

• Ultralight weight — 18.7 g, contributing to smooth flight and easy trick execution.
• ELRS F4 2G4 flight controller with integrated ELRS receiver (SPI 2.4GHz) for easy connection and stable operation.
• Powerful SE 0802 KV25000 motors ensure an aggressive flight style in a compact body.
• Lightweight protective canopy and frame to minimize damage from impacts; frame color — blue, canopy color — black.
• Compact working platform dimensions: 65 mm motor base, body dimensions — 80x80x37 mm.

Hardware and compatibility

The flight controller is based on the STM32F411CEU6 microcontroller (100MHz, 512K Flash Army) with the ability to run CRAZYBEEF4SX1280 target software. The inertial system sensor — MPU-6000 or ICM42688P with SPI connection, ensuring stable and precise attitude control. The built-in video transmitter (VTX) has adjustable power from 25mW to 200mW, and the built-in Dshot ESC is rated for 5A.

Supported power supply voltage — 1S (power supply input voltage 3.3-5.5V). Recommended batteries — 1S 300mAh Li-Po / Li-HV with PH2.0 connector. The built-in ELRS receiver is connected via SPI, antenna connector — SMD ceramic antenna.

Camera and propellers

For video transmission, a lightweight Runcam Nano 3 camera with a 1/3" CMOS sensor and horizontal resolution up to 800TVL is used, mounted in a protective canopy for additional protection during crashes. Standard propellers included — HQPROP 31mm two-blade, providing an optimal balance between thrust and stability.
