The FrSky X8R is identical in every thanks to the X8R Pro receiver, physically. The FrSky X8R may be a receiver that's mainly targetted towards planes and bigger size quads or crafts where size isn't a constraint and where you would like pure PWM pins than S.Bus or PPM. The X8R features a plastic cover to guard it against the weather (which you'll remove to save lots of space and weight, Well again you chose X8R because both these aren't a concern).

The FrSky X8R features 8 individual PWM channels and also has an S.Bus port if you would like to match it with modern flight controllers like the PixHawk or mini quad flight controllers. The 8CH PWM is particularly useful once you want to regulate tons of servos and systems especially on planes and such systems where PWM is especially used. there's also a PWM RSSI output pin for getting Raw Signal Strength Indication for your Flight Controllers.

Design

On the backside of the X8R, there's a sensible Port pin as well! this is often great just in case you would like to attach external FrSky Sensors or provide telemetry data from your Flight Controller to the FrSky transmitter But it a touch weird that they need chosen to put the Smart Port pin at the antenna side of the receiver than on the proper side where all the standard pins are situated; this may mention an irregularity while wiring.

Speaking of the antennas, the X8R consists of two patch antennas (PCB soldered antennas) rather than the traditional dipole stranded wires. Well, you'll connect normal dipole antennas also. The antennas that begin of the factory with them is that the PCB soldered patch antennas. What does that need to do with the performance you'll ask, quite simply, patch antennas provide more range than dipole antennas. But it'll be highly directional.

In the case of the X8R, FrSky claims a further 20% more range! So why not put patch antennas on all receivers? the rationale is that patch antennas are highly directional with higher gain than traditional dipole antennas. Simply put, they receive signals alright during a particular direction ( parallel to the antenna orientation ) but have low signal strength altogether other directions.

This can be useful in some cases where the craft is moving parallel to the transmitter but once it changes its heading, it can lose some signal strength. In most cases, this wouldn’t make much of a difference.

Connectivity

The FrSky X8R from FrSky is an ACCST supporting receiver. we've already discussed ACCST & ACCESS in other posts, so we aren't diving into that during this one. The PWM as discussed is 8CH output and therefore the S.Bus pinout would be perfect for stabilizers and flight controllers.

What differentiates between the R-X8R and therefore the X8R Pro is that the FrSky X8R Pro version has greater precision and minimum latency. Its deviation of PWM is reduced to 0.5us, and therefore the delay of PWM output is 9ms but that of the X8R in high-speed mode. A feature that deserves mention is that the decreased effect of interference caused by the ignition process which is extremely safer to use with the ignition models.

You can use the S.Bus to output all 16CH from the receiver and just in case you would like to use 16CH PWM channels, you'll get an S.Bus to PWM decoder which can translate the S.Bus signals into individual PWM channels for all of your servos.

But that may not all the FrSky X8R Pro receiver can do. It also can add the D8 Mode to figure with transmitter modules like the DHT, DJT, DFT and DHT-U. during this mode, you've got 8 channels and at an equivalent time, you'll use the Smart Port.

Specification:

Dimension: 46.5mm x 27mm x 14.4mm

Weight: 16.8g

Operating Voltage Range: 4V-10.0V

Operating Current: [email protected]

Operating Range: >1.5km (Full Range)

RSSI output: analog voltage output (0~3.3V)

Firmware Upgradeable

Servo Frame Rate: 9ms (HS—High-Speed Mode)/18ms (FS—Normal Speed Mode)

All 16 channels require the FrSky Taranis or the XJT module.

For 8 channels in D8 Mode, you'll use the FrSky Taranis or XJT, DJT, DFT, DHT and DHT-U modules.

Compatibility:

The FrSky X8R receiver may be a great receiver for planes and enormous drones where you would like the full-range capabilities of the FrSky system and breaks out 8 channels of PWM and Smart Port connector with low-latency mode also. In short, these are best fitted to purposes where size and weight isn't a constraint but at an equivalent time, you can't sacrifice any important features.
