Review: Best new micro receiver - Great receivers! With the addition of Sbus capability, I have been replacing all of my D4R receivers with these X4R's and they perform amazingly. Less delay from stick movement to response of my models, and super easy to setup and bind to my Taranis radio. FrSky's X4R-SB receiver features 3 PWM outputs (normal servo) and 1 Sbus port that carries all 16 channels. Plus the exciting new Smart Port and a traditional A2 port are all located on the side port of the receiver. A FrSky FBVS can be connected to the A2 port for simple voltage monitoring. Smaller than the X6R, but still packing 16 channels and the new Smart Port that supports the new hubless digital sensors! Or, connect the new vario, and then connect the old hub to use existing analog sensors. A common question is what can the SBus port do. First off, you can connect it to many flight controllers via a single connection, and now you have access to all 16 channels. Or, you can use something like the FrSky Sbus Decoder, this will allow you to add 4 normal servo outputs (pwm). You can also connect Sbus servos directly to the Sbus line. Just "Y" in as many SBus devices as you need.
Review: S-Bus is very cool..... - S-Bus is the only way to go (at least until the next leap it technology :). 16 channels, faster loop time, great range... Have this installed on my fist FPV quad build, a 210mm. Working great, have telemetry, etc working with my Taranis X9E. Only suggestion is to shrink wrap the antennas with zip tie or straw (to stiffen) BEFORE installing though holes in carbon fiber. Also suggest rounding off sharp edges of holes in carbon fiber (be safe with this though, carbon dust...).... If you don't protect your antennas from the sharp edges of carbon fiber it will cut through the outer jacket, it will short on the carbon fiber and you will lose all connection to your 'copter.... Just a quick tip...

### ⭐⭐⭐⭐⭐ Another wonderful purchase from this seller
*by M***S on August 13, 2016*

Another wonderful purchase from this seller. Received the receiver on time and in new condition. These for me are the best for my 155 and 250 class fpv quads. They are small, light weight, and reliable. I use the smart port for telemetry info and run them in SBUS. I love the built in failsafe in case the other decides to fail...which ive had happen running a naze32 rev 6 and an orangerx 710. Fly aways are no fun. I recommend this for anyone running a frsky tx and need a small diversity receiver on their craft.
