FrSky Archer Plus R6 Lite

In a word, this receiver is a smoking hot deal! Don't let the "lite" designation scare you, this only describes the size of the unit, this is a very powerful receiver for a great price! The R6 Lite is a very nice 6 channel receiver with a great price! Frsky even packed her with Enhanced Anti-RF-Interference capability.

Here is what FrSky says about it:

The AP Lite-series 6-channel receivers feature a compact layout design in functions and are equipped with a 2.4G signal antenna. These receivers have 6 regular 3-Pin PWM signal output connectors on one end, and offer multiple function ports through SBUS In/Out, S.Port/FBUS, and AIN on the other end. 

Through the specific S.Port cable, the receivers can be easily connected to additional sensors, feeding telemetry to the transmitter. When the S.Port is set to FBUS mode all FBUS-capable devices can be directly configured through the ETHOS system using Lua script tools, and in FBUS mode, the receivers can output 24 signal channels in total.

(*Some features require the support of ACCESS and ETHOS.)
