Happymodel FLi14+ 14CH AFHDS 2A Mini Receiver (FlySky Compatible)

The Happymodel FLi14+ is a 14-channel 2.4GHz receiver that binds to FlySky transmitters using the AFHDS 2A protocol. At 1.7 g and 25 × 15 × 5 mm it fits micro quads, small planes and RC cars where a full-size FlySky receiver won't.

Key features

• AFHDS 2A protocol for FlySky radios that support it
• All 14 channels over a single IBUS serial output, so one signal wire runs to the flight controller
• RSSI reported on channel 14 for an on-screen link-quality readout
• Two 70 mm antennas; mount them at 90° to each other for the most consistent reception
• 4–6.5V DC input, so it runs from a flight controller's 5V pad

In Betaflight or INAV, wire IBUS to a free UART RX pad and set the receiver to serial IBUS. The number of usable channels depends on your transmitter; a radio that sends fewer than 14 simply leaves the rest unused.
