FMS Reflex V3 Mini Gyro Flight Controller for RC Planes | Stable Flights, Easy Setup

Overview

The FMS Reflex V3 Mini Gyro Flight Controller is engineered for remote control airplanes that demand calm, responsive handling. It packs a fast 32-bit ARM processor and solid-state sensors into a compact board, translating your stick inputs into confident, stable flight performance—even in breezy conditions.

Designed for broad compatibility, Reflex V3 automatically recognizes SBUS, PPM, and PWM inputs and works with radio systems that have four channels or more. For four-channel transmitters, you can use the included jumper to select flight modes via the gyro mode input, offering flexible configuration without extra wiring.

Key capabilities

• Onboard high-speed 32-bit ARM processor enables rapid calculations for responsive flight behavior.
• Solid-state three axis gyro and three axis accelerometer provide accurate attitude data for smooth handling.
• Automatically recognizes SBUS PPM or PWM input, compatible with radio systems with four channels or more.
• For four-channel transmitters, the included jumper selects flight modes through the gyro mode input.

Ease of use and setup

Reflex V3 is designed for plug-and-play operation with no extra programming required for most aircraft. Connect your receiver and set up the aircraft as you normally would, then verify all controls on the transmitter.

• Reflex V3 can connect to a mobile app via Bluetooth after power on, unlocking parameter setting functions for non FMS models.
• Parameter tuning can be performed through computer software or the mobile app, enabling you to synchronize required parameters for your aircraft.
• User-friendly operation includes mapping channels and directions on the transmitter, guided by the enclosed manual.

Additional tuning flexibility comes from the ability to share parameter configurations between devices. While results vary by airframe and conditions, Reflex V3 provides a practical path toward more stable flights and refined control characteristics without complicated setups.
