X4R wiring

  1. No soldering required for smart port Telemetry review by nathan on 2/25/2016

    Great RX and the others have said. I just wanted to comment that the unit i got on 2/25/16 has the smart port cable already connected to a JR servo. So no soldering or anything required if you are going to use one of the X series of Telemetry units. The product picture and the diagram below make it look like you have to make this cable yourself. It must have come with bare ends at some point and was updated.

  2. Wonderful addition to the X Series review by Matthew on 1/7/2015

    I will admit freely I am biased, I love my Taranis, and I love the X series Receivers. the X4R is the perfect addition to the line, allowing you to install a very light telemetry receiver in aircraft such as a Radian, and still be able to use the High Precision Vario or Lipo Sensor. Sometimes the X8R is a bit of overkill, but with the X4R you have aclean easy install and same great reliability and RSSI peace of mind, This a no brainer to add to any 3 or 4 channel setup.

  3. great...but missing a feature of the D4R-II review by DaddyBigas on 11/19/2014

    This is a great receiver offering all the benefits of X series, plus an analog in. I really like this receiver. If it offered CPPM it would be 5 stars instead of 4. CPPM would make this a perfect successor to the D4R-II.

  4. Best receiver for 4 channel planes of small and medium size. review by Hans on 9/22/2014

    Ideal receiver because of size, weight and price. Good reception at long distance so it can easily be used on medium (60) size planes or smaller. If you do not need more than 4 channels this is the receiver to use!

  5. Light and able! review by Dave on 8/2/2014

    I enjoy building many of pat trittle a 3 channel, small park fliers and this little jewel is perfect for them. Good work, frsky!
