A video on configuring the Eagles would be good (the Super 4 can be daunting). Also on testing the results before flying, I usually set the gain to max and attach a piece of card to the surfaces so when I move the plane around the axes I can see the gyro is compensating in the right directions ;-)

[@jasonhurdlow6607]

Glad to see ELRS options becoming available. Hoping to see lots of new fixed-wing stuff coming soon.

[@RCVideoReviews]

ELRS 3.0 is a game changer and I believe it opens up the opportunities for hardware developers. We'll see. I have high hopes.

[@LeonardoCostaUSA]

@@RCVideoReviews It means that a monkey will be flying when that is available?

[@garywhite7080]

Great Video thanks for all the work you do for our hobby !!! and i would love to see a full blown video on the hobby eagle setup

[@RCVideoReviews]

Thanks for the kind comment. I've noted your request. That might be a good one to cover. These are excellent gyros.

[@hspeed3656]

Great explanation John. Ya you should do a video on full installation etc.

Hi greetings from Germany! I really appreciate your insights on this topic. I also tried to pair cheap Express LRS receivers (without PWM) with a Kopilot Lite and couldn't achieve it so far. Yesterday I tried your way with the converter and a Betafpv 2400 Lite and it works like a charme! The nice thing with the smaller Betafpv receiver is that the size is very small and you can achieve a very small pack. That's really cool. Next thing will be to integrate it in the A3 Super 4 directly (have one laying around here), just need to create a new housing for both of them. In this way it would be very tidy and neat. Many thanks for your streams and all the other topics on RC! Cheers Rene

[@RCVideoReviews]

You're welcome. I'd be interested to see what you come up with for an integrated rx/a3s4.

[@minigsreiter9850]

@@RCVideoReviews I'll keep you updated on my progress. By the way I really struggled with a second receiver plus crsf to sbus converter-board. Couldn't get it to work together with the A3 Super 4. Then I realized that I paired this receiver before with a drone FC. And for that I had to invert the TX-Pin and change the UART to 115200. ;-)! So for all people out there who made any customizations to the configuration of their ELRS Receivers with the crsf to sbus converter only the default values will work. - Uninverted TX - 420000 Uart Baudrate! Cheers Rene

[@Clickmaster5k]

I think ELRS supports Sbus as part of the firmware options now. Might be worth updating the video description and maybe just making another vid about changing the options and pointing people to that one in the description to this one.

[@jingadin5181]

I gained very valuable information on configuring the Hobby Eagle A3S4 from your video with ELRS. I would really like to see a video dedicated to the A3S4 configuration.

[@RCVideoReviews]

There's a search option on each channel to hunt for videos. kzbin.info/www/bejne/qZO3eWqbZbmjZtU

[@cagmuer]

Those bumps on the antennae are just normal di-poles but in an in-line shape rather than a T-shape. The LNAs (Low Noise Amplifiers) are a chip on the receiver between the antennae and the RF chip. So feel free to swap antennas if they get damaged or if you want a different antennae or a longer one to mount on the plane differently. LNAs are a good topic for a video maybe.

[@sansjunk]

A3 Super 4 now supports direct CRSF serial receiver protocol by upgrading the firmware to version 1.6.

[@RCVideoReviews]

Yeah, that's been out for a few months now.

[@TK-bg6gq]

Glad you made this video. it has helped clear up some things a bit with the hobby eagle/open tx interface, but 'm still unclear how to set up gains. I normally just use normal mode (off or acro?), autolevel (horizon aka intermediate), and full angle mode (stability). pretty much a straight AETR setup with the ailerons sharing Channel 1, and flaps on Channel5, flight modes (A3pro commands) channel six and set the gains to channel 7 or the dial. I have been using the red A3pro v2 with some of my aircraft with success using a FlySky 14+ 14ch mini 2A receiver with ibus outputs. But I cannot figure out how to set the gains on the right variable knob, and make them work using only the radio. I have an apple laptop, so using it only presents more problems. I hope you read this before tonights podcast which I plan to watch. Also having trouble on one plane getting flaps to drop in the slow up and down deployment,.....if that's a real word?!?!?!? incorrect inputs/outputs or mixing??????? Anyways, I'm a Big fan of your videos and appreciate your work very much. Thomas

[@TK-bg6gq]

Nevermind, I think I just figured out what Im doing wrong. smh

Thanks Alan.

[@alantoseland6629]

@@RCVideoReviews no, thank you!

[@viciouschloe]

I'd love a full setup video, better yet setup and demo of the different modes while flying. :) Also, Is there any CRSF to XRSL2 boards? Coming from a Spektrum world, I'd love to use an AR637T as the flight controller, but binde with ELRS. So, if I could just plug into the XRLS2 port with an ELRS receiver, I can then get the Spektrum gyro and telemetry functions. Or am I missing something here?

[@MrLightstuff]

The A3 Lite that replaces the A3 L has a spot for the throttle now too using sbus, and it works great with crsf/sbus converter. The A3 Mini is programable, sbus only, but I couldn't get the crsf/sbus converter to work with it, so I used D8 instead.

[@RCVideoReviews]

Good tip on the Lite. It doesn't have A2/E2 though. It also looks like the mode channel #5 is not re-mappable--at least there's no mention of it in the manual.

[@paolo9535]

this is really great 👋👍

[@RCVideoReviews]

Thank you! Cheers!

[@Amplitudeification]

I'd really love to see you redo this with a larger ELRS receiver like the RadioMaster ER8 and the A3 Super 4 with a CRSF connection between the two. So, it would be a combo of serial data and PWM output. That way flaps, landing gear, and even lights could be direct to the RX, with Ailerons, throttle, rudder, and elevator connected to the A3 Super 4, which would be getting connected to the RX via CRSF. Especially if there is a way to Y the CRSF connection so that external telemetry data could could still work.

[@tvhs1975]

A great thorough video. Thanks so much. Im interested in HobbyEagle configuration. Wouldn’t it be at that point easier to use a flight controller? Im still learning. Really appreciate the amount of knowledge on your videos and i dont mind if they become an hour long 😊.

[@RCVideoReviews]

I don’t think so. INav/bf is substantially more complex than a gyro. You also have to care for pwm output which means a wing fc. Those are around $75 to start.

[@dandork20]

Video on that hobby eagle gyro would be awesome 👍

[@RCVideoReviews]

I think you're right. A video on the A3S4 would probably be a good idea.

[@borisdamole]

Even easier now that SBUS works on ELRS 3.2! No need for the converter board anymore!

[@RCVideoReviews]

Cool isn't it? kzbin.info/www/bejne/ppzJnHuGjN2omtU I don't think it's in 3.2. I think it will be 3.3. 3.2 was released Jan 23. It's been merged into the master though.

[@davidwatkin1484]

👽👽👽👽👽👽👽👽👽👽 Hi John, thanks for the video. Concise delivery, love your work. The ZOHD Kopilot uses Ch5 for mode change. How do you get around this with the ELRS Ch5 requirement for arming? Look forward to your videos in 2024. Have a good one.

[@RCVideoReviews]

We use 333hz 16/2 which gives us 16 proportional channels. Then we turn off dynamic power and set it to whatever max you think is necessary (250mw is the max on internal ELRS, so that's what I use) and I ignore arming. Just treat it as it it doesn't exist. Ch5 can then be used for mode.

[@zipppiz]

This is exactly what I wad looking for. I have three A3 V2 on order. Now would it be possible to connect Out 2 to the esc and then use this with ELRS since I plan to use it on a flying wing and it only needs the aileron and elevator to be connected to the Gyro. 🤔🤔🤔

[@RCVideoReviews]

Yup, will work fine.

[@nakul3424]

Thanks for this video, do you happen to know amp rating of this gyro? i could not find this info anywhere, not in the manual or the website, etc.

[@RCVideoReviews]

I don’t know. Personally I would plan for no more than a standard BEC. About 5a. I’ve been using power distribution boards if I need more. Servo city has a 15a continuous 30a burst board for $13.

[@MrLightstuff]

Be advised. The new Matek PWM6 only works with elrs 3.0, but 3.0 is not backwards compatible with previous elrs rx. I had to go back to 2.5 on my main radio and put 3.0 on my little radio. One reason, like you said, not to fly with it yet.

[@RCVideoReviews]

It makes sense PWM 6 converter only works with 3.0 as 3.0 is the version that provided more than 4 proportional channels. I didn't say not to fly with it. I've been flying with 3.0 for a couple of weeks now and on some of my nicest planes.

[@dezp1874]

Hi, do you have anything on how to connect the Radiomaster ER5A receiver to a Pixhawk 6C. We are looking for range control on our boat plus autonomous travel option on the boat?

[@RCVideoReviews]

Sorry, I don't. I can tell you ELRS 3.3 enabled SBUS, so if your Pixhawk supports SBUS, you could turn that on. It works on Ch2. However, no telemetry as SBUS is unidirectional. You'll only get telemetry from the Rx itself.

[@LeonardoCostaUSA]

mannn .. Elon Musk needs you on his company !! I've never seen anybody explaining something that difficult in a easy way like you did !! thank you very much for your video! by the way: any video about that subject I will be watching for sure!

[@RCVideoReviews]

Thanks. Glad you found the information useful.

[@banzaiib]

FYI, for those, like me, referencing this much later... you can (now) set to 333hz 1/2 rate in your CRSF config / lua for no ch 5 complexity. I've done this on a glider and now on my F-14 with an ER8 rx.

[@RCVideoReviews]

Ch5 is still required for certain features like dynamic power. Using 16ch mode just makes Ch5 proportional instead of binary. Does not eliminate the need to use Ch5 to "arm" the receiver if you're interested in the features "arming" provides.

[@BryonGaskin]

The Elrs devs say no sbus (for a lot of technical reasons that are beyond my grasp), but the one one thing they said why no Sbus is because it s a legacy technology. True, but there is a ton of old hardware out there (especially if you don't go with an FC) that only supports PPM or Sbus (e.g. like the Byme A / D. I've basically converted all my FC based wings/planes to ELRS, the only holdouts are is the one kopilot I have with a crossfire nano (because it supports sbus out)

[@RCVideoReviews]

The sbus adapters are work-arounds to direct sbus support from ELRS. I still hold out hope they'll add it, but in the meantime, we have a small little $3.00 card to do the job.

[@markhaman2018]

I watched your video and have Matek R-24-S (Had one from a Quad in a box) and HobbyEagle 4 flying a Tech one foamie using SBUS on a single wire. Throttle is coming off the Hobby Eagle. I am not running the SBUS converter. I thought I was good to go but I need help with bigger A/C and Helis due to running 2S voltage to my HV servos. I cannot run that voltage to these receivers. I am looking for work aounds you may already have working. I have some of the new RCVRs coming from Radiomaster that can handle the higher voltage. It is more about how do I run 5 V to Rcvr and 8.4 Volts to servos. I know I have seen you cover it. I run SBUS to IKON on Helis and starting to use the Hobby Eagle4s.

[@RCVideoReviews]

You could put a BEC in front of the RX.

[@markhaman2018]

@@RCVideoReviews Thank you. I have ordered 2 with 5 volt output just in case. The voltage input shows 4-9 V on Matek R24-D (and -S) but I am hesitant to put 8.4 volts on a 5 vold pad. What voltarge are you running on the PWM converters or any other setups to the 5V pad. That is step one with a foamie to start. I'll work up on the bigger servos.

Hi , sorry i'am new in this hobby, i just bought a Radiomaster ELRS 6Ch pwm , Can i use it with A3Pro V1 ? Thanks

I've only seen the v2, but if it's PWM and you have an ELRS PWM Rx you can use them together.

Could I configure a 6ch PWM tracer receiver via Sbus?

[@RCVideoReviews]

Not sure. I haven't used tracer.

[@publicname515]

The 5 output limitation using SBUS is a deal breaker. There needs to be an ELRS receiver that has BOTH pwm and SBUS outputs. I use the Matek 10ch ELRS PWM converter + receiver. Unfortunately that has 2 UARTs, but the 2nd UART is designed to be used with a GPS sensor not an SBUS connector. I'm emailing Matek to see if it's possible. I'd just go with wire convenience for SBUS is really nice. But I use this on jets where I need more outputs.

[@RCVideoReviews]

I outputs can be easily remapped in the firmware on the x10. You can just have it ignore ch5 and skip to 6.

[@ShahriarFarkhan]

Thanks, this was useful! Do you know if the software works on Windows 11? My huge worry with these companies using phone/computer apps is future support. Once they stop updating their apps (or in the case of phone apps do a crap job) their hardware is a paper weight.

The crsf to sbus board is discontinued. How about a video on using V3.3 with sbus support.

[@RCVideoReviews]

Plenty of videos on my channel covering this already...

[@barryh9748]

How do you power it if you are using all of your output pins for servos?

[@RCVideoReviews]

Pin 3 in the video goes to an ESC which provides throttle signal to the ESC, but the ESC lead provides BEC voltage to the RX and subsequently to the gyro over the SBUS wire.

[@barryh9748]

Thanks for the response. I'm doing PWM with the throttle and flaps going straight to the receiver which is elrs going through to the sbus to 16 channel pwm decoder that you used in a prior video. I tried going from channel 6 from the decoder to the mode port but got really erratic results

[@barryh9748]

I figured it out, I plugged the esc into the gyro instead of the decoder and it's working as expected now. Thank you for your help

ok i have the a3 super 4 and a matek crsf -pwm-c board with an elrs reciver everything works great except the modes it only changes between the first and last mode how can i get all 3 modes to work

[@RCVideoReviews]

You should get on Discord and ask there, it is a better platform to work these questions out. Do you have the mode switch on a 3 position switch? Is that 3 position switch sending -100, 0, 100 in your channel monitor? Do you have three modes configured in the stab?

Q: Is the Matek R24D still your go-to ELRS Rx? (I'd like to go order a bunch; I like Matek's quality.)

[@RCVideoReviews]

R24D is very good for a serial only RX. I use those when I need them and I have them in my stash. If I order new, I usually go for the Radiomaster RP4TD. I use ER6/ER8 for PWM.

does it work with DX9 SPECTRUM? tks

[@RCVideoReviews]

Does what work with Spektrum? The gyro accepts PWM in, so if you can output PWM from a Spektrum Rx, then yes it works. I have no idea if Spektrum supports sbus out for single wire. You'll have to google that one.

[@FAA-DPE]

Thought I'd use a Spectrum Satellite into SBus But there is no way to power the gyro and in turn power the servos, as I'm using all 5 gyro outputs to the 5 servos in my airplane. There is no way to feed power into the gyro with 5 servos connected to the gyro and the Satellite going into the SBus slot. Into the garbage it goes, and hello Bavarian

[@theoztreecrasher2647]

That's BS Mate! Just use a y-cord for 1 of your connections and feed the 5v from the BEC into the free leg +/- pins. That'll power all the + and - bus rails on your receiver and the gyro! You might need a DSM satellite adapter to match the 3.3v rails of most Spektrum satellites though.
