FMS Reflex V3 Gyro Stabilizer Flight Controller for RC Planes

The FMS Reflex V3 is a gyro stabiliser for RC fixed-wing planes that corrects attitude in real time using a solid-state 3-axis gyro and 3-axis accelerometer. It fits FMS models and non-FMS airframes alike, making trainers easier for newcomers and small, light planes steadier in crosswinds.

Key features

• Three flight modes: Stabilized (full self-levelling for beginners), Optimized (gust and wind rejection with full manual authority) and Manual.
• Modes switch in flight from a 2- or 3-position transmitter switch.
• Bluetooth link to a mobile app for parameter setup, with no laptop needed at the field.
• Accepts SBUS, PPM and PWM receiver input.
• 32-bit ARM processor in a red high-impact plastic case.

Specifications

• Sensors: 3-axis gyro + 3-axis accelerometer
• Processor: 32-bit ARM
• Operating voltage: 4.8 to 7.4 V
• Receiver input: SBUS, PPM, PWM
• Weight: 10 g (controller only)

It is powered from the receiver bus, so keep your BEC output within 4.8 to 7.4 V; a 2S LiPo fed directly reaches 8.4 V when full and exceeds that limit.
