FlySky FS-SR12 12-Channel 2.4GHz ANT Receiver — Dual Antenna for Drone, Fixed Wing, Car & Boat
$101.57
Description
The FlySky FS-SR12 is a compact 12-channel 2.4GHz receiver built on FlySky’s ANT protocol, engineered for pilots and builders who need precise, multi-output signal control across a wide range of RC platforms. Weighing just 13 grams, its dual-antenna design delivers stable reception and an operational range exceeding 1500 metres in open air — with PWM, PPM, i-BUS, and S.BUS output options covering virtually every flight controller and ESC combination in use today. Compatible with fixed-wing aircraft, multirotors, helicopters, gliders, boats, cars, and robots, the FS-SR12 is a versatile, low-profile receiver that fits into tight builds without compromise.

Why This Receiver
- Broad signal output compatibility: PWM, PPM, i-BUS, and S.BUS outputs mean the FS-SR12 works with virtually any flight controller, servo bus, or ESC on the market — one receiver for your entire workshop.
- Dual antenna diversity: Two antennas work together to maintain the strongest possible signal lock, reducing the risk of dropouts from orientation changes or obstructions during dynamic manoeuvres.
- 1500m+ range for serious flying: Exceeds the range requirements of most sport and intermediate RC applications — from park flying to longer fixed-wing cross-country runs.
- Ultra-lightweight at 13g: Minimal weight penalty for any build — ideal for weight-sensitive multirotors, micro fixed-wing, and competition-grade aircraft where every gram counts.
- Wide voltage tolerance: 3.5–9V DC input accepts direct battery power or BEC-regulated supply, simplifying wiring and reducing component count in compact builds.
Care & Maintenance
- Cleaning: Wipe with a soft, dry cloth only. Do not use solvents, compressed air directly on connectors, or abrasive materials.
- What to avoid: Do not expose to moisture, water ingress, or condensation. The FS-SR12 is not waterproofed — protect it with heat-shrink or foam mounting in exposed builds.
- Antenna placement: Position dual antennas at 90° angles to each other for optimal diversity reception. Avoid routing antennas parallel or bundled with power wires.
- Connector care: Handle servo and bus connectors gently. Inspect periodically for bent pins or loose retention. Re-seat connectors fully before each flight session.
- Storage: Store in a dry, room-temperature environment. Remove from the aircraft if storing long-term to prevent connector corrosion from humidity.
Frequently Asked Questions
Q: Which transmitters is the FS-SR12 compatible with?
A: The FS-SR12 uses FlySky’s ANT protocol exclusively. It is only compatible with FlySky transmitters that support the ANT protocol. It will not bind with AFHDS or AFHDS 2A transmitters (e.g., FS-i6, FS-i10, FS-T6). Check your transmitter’s protocol specification before ordering.
Q: What signal output types does it support?
A: PWM (individual channel outputs), PPM (combined pulse), i-BUS (FlySky digital bus), and S.BUS (Futaba-compatible digital bus). Select the output type that matches your flight controller or servo setup.
Q: What is the operating range?
A: Over 1,500 metres in open air under clear line-of-sight conditions with no interference. Actual range may be reduced by physical obstacles, electromagnetic interference, or adverse weather.
Q: Is a transmitter included?
A: No. The FS-SR12 is sold as a standalone receiver only. A compatible FlySky ANT protocol transmitter must be purchased separately.
Q: Can I use this in a car or boat, not just aircraft?
A: Yes. The FS-SR12 is compatible with ground and water-based RC models including cars, boats, and robots, in addition to all standard RC aircraft types.
