FXT FX888R 5.8GHz 48CH Triversity Receiver Has Anyone Used One?


Hello All,
I am looking to build a basic ground station and this caught my eye:
https://www.banggood.com/FXT-FX888R-...iddle_products

If anyone has used this receiver please let me know what you think of it.
How well does it work?
What antennas are you using?
Would you buy it again?
I'm on a tight budget and can't afford to buy the wrong diversity/triversity receiver so any info or recomendations is much appreciated. Thank you.

Im getting one, will tell if it's worth it.
But if you have fatsharks you could just use cheap diversity module, with custom achiles FW. it works great.

Id like to see how well it works too. I want to have two vas 12.5dbi helical antennas and a pagod antenna for maximum penetration through forest.

I was wondering about the possibility of firmware hacking one so you can tune the 3 receivers in to different channels.. It already has a dedicated output to the 3 individual receivers, so doing that to 2 of these would give you 6 different channels which would be awesome for a recording station..

Not for Goggles + DVR


Sadly but at this time NO it can only work with one same channel to all outputs (that would be great if it could work separatly so it would have 3 dvr lines !)
also only one combined video out would be nice to have 2.

well may be in next version they will listen to our needs!

BUT! it still great unit, works great. (used it with stock antennas for indoor races)

I will write my review here... since no need to open multiple thread for the FX888R




Disclaimer (inspired from SP) Product specifications and quality may vary at the manufacturer's discretion, and are beyond my influence. I cannot guarantee you will get a product that performs exactly the same as seen and described in this review. Please, no savage affiliate links! . By the way, in contracdiction with some other reviewers, I open a new mini-review thread ONLY when I have the machine in hand ....

INTRODUCTION

The FXT FX888R tripleplay is new 5.8G ground station receiver integrating up to three difference sources. In practice, coupled with high gain "120" degrees directional antennas, you can cover 360degrees.. and by consequence gain easily 6dBm (and more) at least to double your FPV range. Other antennas combinaison can open even more long range applications. The tripple play is a small 48CH 5.8G module where each receiver can be enable or disable individually. Let's have a look to this new 5.8G receiver.


BOX CONTENT



+ 1 x FXT FX888R
+ 3 x 5.8G linear antenna with SMA connectors
+ 1 x Powerlead cable with XT30 connexion
+ 1 x AVout 2.5mm jack plug to RCA connectors (video & audio)
+ 1 x Instruction manual (English)




The choice of a 2.5mm jack plug is less common than 3.5mm for FPV equipement.

OVERVIEW

The plastic design of the casing is pretty nice with a good plastic material. You take the module in hand you are positively surprized by its light weight.



All the connexions can be done on the right side. Three individual AVout corresponding to each 5.8G receiver and a "triversity" output. We can regret maybe the absence of a second triversity port in order to plug also an external DVR directly.



The left side welcomes only the powerswitch



No problem to attache the triple play module on a tripod




SMA connector for each individual receiver antenna port





The front pannel display the current selected Vband,Vfreq as the instatanenous power received on each receiver.




It's super easy to select a Vfreq, i.e. short pressing will cycle among the eight ones in the current selected band. If you long press one it, you cycle between the six supported Vband

The complete list of supported Vband & Vfreq



It's possible to turn on/off individually each builtin receiver




UNBOXING AND TESTING

A super easy to use module ..... Maybe some futur owners can regret the XT30 connector instead of a JST one but since the module can accept battery up to 6S, the XT30 is more logical for such wide voltage range.

FXT FX888R tripleplay unboxing and testing (Courtesy FXT) (12 min 10 sec)


The test has been done with a simple 25mW source with a linear antenna. The comparaison is done with a FPV monitor including diversity. Both source have been recording with the same EV100 DVR with the same settings (HD resolution). Of course this particular test can be critiqued but a long range FPV comparaison depends also of the powersource, the current altitude, level of multipath, etc.... We can feel a slight improvement of the level of reception especially for low SNR conditions and for high RSSI, the level of statics also a bit decreased. We can notice also the desynchronization of the DVR recordings... I liked also how the switching is done... not to fast and absoluptly no break up can be noticed during a switching. The level of each RSSI is displayed only the front OLED screen. No OSD informations overlayed especially the current battery status.



CONCLUSIONS

Good, relatively cheap and simple triversity 5.8G module.... The ensensial is here. The 5.8G switching is well done and the general improvement even if it's small with the actual linear antennas will be here as soon as higher gain antennas will be used. I regret the absence of basic OSD information at least the current battery voltage and the absence of a second AVout to plug directly a DVR. We can hope one day to have a version where for each individual receiver, a unique Vfreq can be selected.


PROS

+ Improves the general RX sensitivity
+ Can cover 360 degrees with three "120 degrees" directional antennas
+ Smooth switching between channels
+ Individual AVout
+ Light
+ Easy to use
+ Cheaper than any competitor
+ Tripod compatible


CONS

- No builtin battery
- 2.5mm jack connexion less common than 3.5mm format
- No second triversity AVout (for DVR connexion)
- -90dBm "only" builtin receiver
- No OSD informations
- No possibility to select three different Vfreq



This 5.8G receiver have been courtesy provided by FXT in order to make a fair and not biased review. I would like to thank them for this attitude.
You can find it actually for 76USD at https://www.banggood.com/FXT-FX888R-6-Bands-48CH-Raceband-Triversity-Receiver-Built-in-12864-OLED-p-1195291.html

SeByDocKy - correct your about info, there is no XT30 connector that's XT60
but you can insert xt30 inside

Ok I just ordered one. I was planning on getting a Quanum Overlord 3 rx (same price but the Overlord has patch antennaes). I chose this due to problems some people are having with getting an accurate lock with the Overloards scan systm, and the fact you cant step through the available channels with the overlord. I hope thie fxt unit works good, I have 3 Tru Rc long range antennas waiting for it.

OK IM STINKY PISSED RIGHT NOW.

Just received this over the weekend, opened it today. As I pull it from its styrofoam support frame I can hear its guts rattling around inside. By hearing alone It sounds to be a heavy piece of plastic tumbling around with a light metal plate.

TOTAL JUNK ! ! ! ! !

SOUNDING LIKE A FUNKING BABY RATTLE.

I just received a package from Getfpv.com last week that was missing an antenna adapter, it only cost me $2. I deemed it not worthy of a complaining email. But now this. Sounds like the pieces tumbling around inside arent even connected by wires, I'm afraid to attach this unit to a battery. Already regretting not buying the Quanum Overlord.

At $70 this is not over.
