iFlight ELRS Dualband 100mW Receiver

The iFlight ELRS Dualband 100mW receiver is built for long-range and heavy-lift FPV drones where control link reliability is non-negotiable. It is available with a 160mm or a 70mm antenna; the longer 160mm lead allows builders to route the active element well clear of carbon fibre frames, large batteries, and HD camera payloads, ensuring an unobstructed signal on bulky cinelifters or 7-inch macro quads.

Key features

• Dual-band ExpressLRS architecture for superior signal redundancy and interference rejection.
• High-power 100mW telemetry output maintains a robust data return link for GPS and battery monitoring at extended ranges.
• The 160mm antenna option provides flexible mounting to bypass carbon fibre signal shielding.
• Standard UART wiring integration fits seamlessly into modern flight controller stacks.

Pair this receiver with a matching dual-band ELRS transmitter module for the ultimate long-range control link. Ensure the antenna is mounted rigidly, ideally using a TPU mount, to prevent the 160mm coax from moving into the prop strike zone during aggressive manoeuvres.
