Build an FPV drone in 2023 - Part 7 - Bind the ELRS Receiver

[@SnoWakeFPV]

Hey JB! Working my way through this (my first) build, and having SO much fun! Got to this step, and - while the getFPV listing is clear on the point that the kit does NOT include a receiver - this video kinda suggests that one is included. Certainly no worries - I realized this before I got to this stage of the build - and ALREADY had an EP1 on hand for an upgrade to my Nazgul bind-n-fly (currently configured for DJI RC2 -- but looking forward to flying it - and THIS build - with my new JB-edition TX16S. Thanks for ALL that you do! #LifelongLearner #SoMuchSurfaceArea #DownTheRabbitHole. From a Phantom 3 circa 2015 - to 4 FPV drones purchased inside a month (Avata, Nazgul, JB Kit, Mobula8). WHEE!!

[@NuHorizonC8]

Hey Joshua I have a questions about remote binding with your kit. Firstly huge thanks for the detailed instructions in your series. I've watched all of it and its given me alot of confidence to go from the casual DJI drones i've been flying to more acrobatic/freestyle drones. My question is can the dji remote 2 work with this build? I read if your using the DJI O3 system, you do not need to use an ELRS receiver as the O3 system has one built in and all you need to do is bind it similar to the Goggles 2 and use Beta flight to bind the buttons appropriately. Is that correct? Just want to make sure I dont accidentally solder things that don't need to do. Thanks again! 👍

[@Mupshot]

kind of a shame the TPU antenna holder doesnt have enough of a recess to allow the ends to come closer together around the plastic hub. it just looks janky with the antenna bursting through. Still functional, but looks slipshot.

[@QuadMcFlyFlies]

I actually didn't use tpu at all on mine. I used the same RX but put it in front under the esc and ran the antenna out front under the camera. I just zip tied the T to the front of the frame. Technically you could do the same thing in the back and skip the weight of the TPU.

[@gregorydahl]

@@QuadMcFlyFlies thats what i did . So at low rc signal i turn around and the antenna gets clser and the quad is not between me and the antenna .

[@Carbon2087]

The one that came in the kit is entirely different, it opens up from other side so you don't even have to take the antenna off

[@24-7evan]

Joshua Bardwell, I can't thank you enough for all the time and effort you put into your videos. they are more helpful than I can begin to describe and you are so happy to share knowledge. I truly appreciate it. I didn't even notice this playlist was SO recent, I have just been watching it because I am going to be building my first quad. I have had RTF's and BNF's before, and have done soldering, BetaFlight stuff, and repairs, but building is new. this playlist is going to be crazy helpful here in a couple days when I start my build! Thanks again for all your effort and being one of the most helpful channels with, "... a link to a video about that in the description box below..." for everything an FPV pilot could ever be confused about or struggle with!

24:00 I really appreciate your attention to detail with terminology in this series. I’m building fixed wing, but had been finding value in this series, so I bought the kit :) I’m concerned about finding a battery, any suggestions? I live in US

[@Baleur]

5:00 but that doesnt match with the wire diagram you showed earlier, the ground had no double pad next to it. So i guess those recievers in that image was NOT the one you're using.

[@JoshuaBardwell]

All ELRS receivers have the same wiring order. The diagram showed one receiver but it doesn't matter that it's not the same as the one I'm using as the wiring is the same.

Where can you get the 3d printed parts

[@CGreciful]

Hey brotha, I couldn't find the ELRS receiver in stock, so I ordered the RP3 V2 ExpressLRS receiver from radiomaster when I ordered my Radio. It has the dual antenna (dipole). I think this should work fine, we'll see! Do you know a good 3D printer resource I could find a mount to print? If not, I'll probably just design one, I have a few rolls of TPU handy.

[@luiskraus1526]

I actually had an error in my vtx pinout diagram, things wouldnt work and it took me a very very long time to figure this voltage-loss out, wouldn't had assumed it being a beginner... lots of headaches later i got it to work

[@dimitarnaydenov90]

Hi, I have a problem with a whoop. The receiver bounds with USB connection to my Boxer BUT when I plug in lipo it does not it is only solid blue. I found 2 wais to connect it but both are not how a quad should work. 1) Connect with a USB and then put the lipo - it flies 2) Unplug the CRSF port(the receiver is with a plug not soldered), connect the lipo, wait for the beeps and then connect the receiver to the port. Works Do you know what could be the problem? Is there a delay start/power for the CRSF port? I gues this will help maybe 3-5seconds deley for the beeping to end and then power the receiver Quad: T-Mottor Tron 80 HD; Receier - BetaFpv 2.4ghz Nano ELRS; Vista; Radiomaster Boxer ELRS 1w build in Thank you in advance :) Hope you will have a solution for me Have a great day :)

Should I have gotten an Express LRS receiver with my Beginner DIY FPV Drone Kit - QAV-S 2 Joshua Bardwell SE 5” - HD Ready kit?

[@mcbewild]

Any way possible with this FC to use the DJI air unit along with an ELRS receiver as well as a GPS/RID unit added? unfortunately, I think not having enough UART's answered my question...

[@ke4yub]

Should have read the comments below. Is it possible to bind the DJI 03 with the Goggle 3 if I only have the Joshua Bardwell Radiomaster tx16s radio? It seems to want me to find the DJI radio and won’t bind. I have loaded all the latest updates.

[@LiveInTheNow-jb4dg]

I'm at the start of the recap. my Tx and Rx are wired correctly. but Beta flight isn't showing any input. Any ideas why not, and how could i fix this?

[@ermanpehlivan2335]

[@CalvinFalk]

Hey JB! Im building this rig using the O3. I am having trouble finding a spot with clearance for the Receiver at the rear of the quad. The o3 with the doublesided tape leaves not enough vertical clearance between the top plate and the ELRS RX (i am using the same unit you are in this build).

I have a Cinelog 25 V2 i'd like to set up now, but hoping i don't have to re-bind the O3 & the receiver every time? How do you set that up? Tried Googling it, but it keeps thinking i'm asking about AUX switches...lol I have the Boxer radio also. Thanks in advance!

I like your "gRRReen = RRRReceiver on FC" convention. However, it's not green, it's teal. T-eal, T-ransmit. R-oyal blue. R-eciever. (also R as in reciever and B as in blue look very similar, RB BR). Enjoy.

[@seppeqespecho4260]

Thanks for the great video series! I have one question though. What about the internal build in receiver of the O3 air unit? I've checked other videos where I got the information that you should cut one cable of the O3 unit so the two different receivers will not cause a conflict. Did I miss this in the video series? The O3 was connected directly to the FC without the need of soldering, was the behavior together with the other Express LRS receiver mentioned? Or do we now have both options in this build? ELRS with the Boxer Remote or the option with some DJI Remote for the O3 build in receiver that shares the channel with Video.. I'm a bit confused.

[@JoshuaBardwell]

This video is showing how to use Boxer with ELRS receiver. If you wanted to use the DJI Controller, you can, but you would configure the FC differently.

[@seppeqespecho4260]

@@JoshuaBardwellThanks for the reply. I think it goes back to this question in your video: kzbin.info/www/bejne/Y3zFXnybjLx-hbssi=EGukZk8ex66TUqMA I assume there is no conflict in your build and it depends on the beta flight configuration if I want to use the DJI O3 system for everything or utilize the ELRS Receiver with the Boxer (or some other ELRS controller). No need touching the hardware again, its about the software configuration. Thanks for the answer!

Yes correct. Just change the software configuration.

Why it will never fly

[@CGreciful]

The Stax datasheet says to connect reciever to UART3. UART4 is for the GPS. Not sure why it worked for you on UART4, but I'm hoping if I switch to UART3 tomorrow my hours of frustration will be over.

[@JoshuaBardwell]

You can use either. It's just a recommendation.

Hi Joshua, you no longer include a receiver in the kit, leaving it up to us to pick one out. If I go with a dual anentenna, will I have issues with the 3d-printed you include?

[@JoshuaBardwell]

The Xilo FC cannot support digital vTX + ELRS RX + GPS. It only has two full UARTs. So you have to change the FC or you have to pick only two of those three. If you are using analog vTX or if you are using FrSky receiver, then you can also use GPS.
