Introduction
The Archer line of receivers has been enhanced further with the addition of the new Archer Plus Series.
The Archer Plus Series receivers include some new features. Firstly an enhanced anti-RF-Interference capability
can offer a more solid RF performance, and this is in addition to the receivers with anti-interfere performance in
the spark ignition process. These Plus series receivers are also with both ACCESS and ACCST D16 modes,
where the RF protocol is smart matched during the binding process on the radio. With the Black-Box function,
some basic flight data (like Power & Signal related) can be well preserved.
The Archer Plus R8/GR8 8 high-precision PWM channel receivers supports full-range signal strength with dual
detachable antennas and guarantees optimal antenna reception and range. The R8/GR8 can be used as a
Primary receiver in a redundant solution by wiring the SBUS In port and connecting to any other FrSky receiver
equipped with an SBUS Out port. With the FBUS protocol, the Archer Plus series receivers can open up the
possibility of seamlessly pairing with multiple telemetry devices (XACT servos, ADV Sensors, etc.) as well as
simplifying the builds setup.
The Archer Plus GR8 are receivers with an upgraded high-precision variometer that gives pilots more accurate
and quicker altitude and vertical speed data, and also features its more accurate and quicker vario audio
feedback from your FrSky ACCESS enabled transmitter.（Archer Plus GR8）
