FrSky R9Slim and R9Slim+ Receiver Shootout, What is the difference?

[@mark685]

For polarization, the RX antenna should be horizontal if the tx antenna is horizontal. Also running the feeder parallel to the antenna like that will really distort the RX pattern. I would expect the tbs antenna to work best. Of course the carbon fiber frame distorts the pattern too.

[@kkrampus]

They are the exact same dipole antenna, just one is pure wire and one is in cased in plastic for durability. Treat your diversity setup like you would with the 2.5GHz (90deg from each other) and have the single antenna set up in the most likely way your ground would be set up (if ground is vertical have it vertical, if ground is horizontal have it horizontal).

[@MCsCreations]

Awesome, Mark! I'm seriously thinking about getting that module for my Taranis and a R9 receiver, to my TBS Discovery build... Don't know yet, let's see. 😊

[@BBooka]

O yea this will be very nice to have video about all possible ways of connecting RSSI. Also this is very nice video where clearly showing all differences between different product models. (Y) I like such detailed videos. (Y)

[@NATGEOANDSTUFFPaulbrannan]

still love my rxsr but this is still good for certain builds

[@SimRacer101]

Yea, this won’t totally replace my 2.4Ghz, but I think I’ll be using it a lot, especially once I have the mini.

[@NATGEOANDSTUFFPaulbrannan]

DroneRacer101 sounds good buddy.

[@dronereviewman9580]

Great channel!!! I really like how you do everything!!!! YOU ARE THE MAN!! ⭐⭐⭐⭐⭐

[@DKFPV]

DRONE review man dude why you are always so excited about any video that is coming out? I see your comments under every video and they are always the same.

[@Fredd32]

Keep em coming....good stuff

[@achefpv6521]

Can I use a slim plus in a mamba f405 flight controller?

[@simonkatz3779]

On the slim+ does it have to have 2 antenna at once or can one be removed? On GetFPV it does say one is detachable but I'm wondering if doing so would limit its capabilities?

[@TexasWaters]

Good for Fport, maybe.

[@davidm8293]

hi! great channel, you have a new sub :) . I am just getting into fpv drones, and my first one is on it's way, do I get it right that this receiver does not work with 4s batteries? I am building the uav 99$ build with 4s batteries, but they didn't include a receiver, so looked around and bought the r9slim+. If it is not compatible with my drone which one would you recommend, I also purchased the r9m lite module for my frsky x9 lite.

[@MarioATEFPV]

Great Video!

[@SimRacer101]

Thanks, I’m still learning too, but trying to make it clearer for people.

[@ElmersFPV]

Hey dude.. Thanks for that video. I have a question about the voltage. The manual says it works with "100mA on 5V". Does it works with more mA if I use it with 10 or 12V?

[@sten6537]

Hi Mark! Can you tell me how I can get RSSi with the R9slim + receiver on my CLracing F4s FC? There is no RSSI pad but i read somewhere that I can get the RSSi via the tele pad? My TX shows the RSSI value bytw, so that means it should be possible to get it on my OSD right?

[@Aridrona]

I have the same board, ever figure it out?

[@obinnaeke8067]

So if I want to connect my s.port to my pixhawk telemetry to run a lua script, I can do that without using an adapter? Or how does that work?

[@SimRacer101]

I don’t have a Pixhawk but looking at some diagrams it uses an RS232 port so from this you are still going to need a adapter.

[@MCsCreations]

Obinna Eke The smaller receiver can work that way. The slim I really don't know.

[@obinnaeke8067]

But I do not need the adapter when using an omnibus board then? So in that case I could just run arduplane on my Omnibus V3 if I needed the lua script right? EDIT: NVM, just found the anwser.

[@FunTechandMore]

Can you do a video of the r9 slim vs r9 mini? Please there is no video like that

[@SimRacer101]

As soon as my Mini arrives.

[@FunTechandMore]

DroneRacer101 nice also on how many servo outputs there are. Thanks a lot

[@MrLDavids]

This makes it seem like you can use the same UART to connect S Port and S Bus. Rx to Tx, Tx to Rx on same UART...?

[@SimRacer101]

It would be nice, but unfortunately with current hardware you can’t do it. Betaflight doesn’t support it.

[@AntonisAnastassiades]

I got the R9 Slim+ and wanted to connect the TBS Crossfire Immortal T ant. The receiver though has actually comes with two antennas attached. Could I still use only one with the Immortal T and if so, which one should I remove?

[@SimRacer101]

You can. I did the same thing with my inav wing. My first iNAV build and test flight with an S800 Wing kzbin.info/www/bejne/gJOYpYOfgrWeY5I. Doesn’t matter which you swap.

[@AntonisAnastassiades]

DroneRacer101 so should i remove both and keep only the immortal t? Also do u think it will perform better than the two antennnas?

[@SimRacer101]

No, use the Immortal T and just keep one stock.

[@bryanfpv]

R9 slim has uninverted s.port pad or pin?

[@SimRacer101]

Mine did not. But I was told they added a pad to some of them.

[@dronedoutrc5970]

Whats your take on the r9 mini? I have been testing my self but need some more time to give a proper opinion.

[@SimRacer101]

I still don’t have one, it’s on the slow boat.

[@dronedoutrc5970]

DroneRacer101 dang boats

[@SimRacer101]

Actually, it just arrived today. 😁

[@dronedoutrc5970]

Nice. Let me know what you think. I am having mixed results at best. I think frsky needs to update the fw a bit. F.Port kind of a screwy with the sensor lost issues. Still trying to get rssi to the osd too.

[@dronepilot1333]

Will R9 slim+ connect to omnibus f4 pro and APM 3.1?

[@SimRacer101]

Yes, the + won’t have any problem connecting to either.

[@dronepilot1333]

@@SimRacer101 Thanks

[@maxun1]

rxsr, tested garbage, r9L, tested good, x8r good, xsr garbage, x4rsb good, r9slim good, r9slim Plus good, make shure you update the firmware in the r9 series. R9 slim plus 26.99, the r9 slim is discontinued. but is a great receiver.

[@SimRacer101]

Ah, thanks, I hadn’t seen yet that they were discontinued. I’m not really surprised.

[@maxun1]

yes I just did the update of the R9Slim plus, look good I use com1 wires to update the firmware, positive negativa and sport, all smudd and nice. bind right away.

[@Ivar1231]

There is not a single decent video on wiring that stupid R9
