The D series receivers are FrSky's first telemetry units. Rock solid and reliable, yet very affordable. This is where FrSky really got rolling with their telemetry capabilities.
All receivers feature built in receiver voltage sensor and RSSI feedback. (Receiver Signal Strength Indication, it warns you if your reception is getting low at the receiver, this saves your aircraft and makes the hobby safer!)
Compatible with all FrSky transmitters (bind in D8 mode) and also the D series modules like the DFT, DJT, DHT and the DHT-U. Sadly this line is shrinking and there are few sensors left that will work with these receivers. Also, these units are limited to 8 channels.
