ELRS Gyro Stabilization WORKS! 

Impressive! Soon I can bin my Frsky S6R receivers 😁. There is a serious market for these new ELRS gyro receivers!

Ironic that this is probably the same accelerometer in the flight controller that's in my $1000 plane.

Great and thank you, I did all the steps and I had Success flashing but I can't get the binding mode for the BETAFPV superp 14ch?

This is really great. Thanks for posting! edit: I got this working on betafpv super-p rx with a few notes. Could not get any flip mode gyro orientation settings to work, the work around is just invert non-flip outputs. You must manually set PID & gain values they default to 0,0,0,0 thus no output. Again, really cool though.

It’s good times to fly RC. Everything is improving so fast. Even tough it’s experimental, this conforts me in my decision to migrate everything to ELRS. And off course thank you Alex. 🙂

I ordered 3 gyros to support ya 🎉

Thank you again for you info! Really helpful! From what I see but with some differences, we could actually make the elrs RXs behave like a spektrum safe/as3x RXs!

radiomaster ER8 don`t work, the LED from the Gyro is red... Can you help?

SAFE is registered to Spektrum. Alex might have to pick another name. I believe what he calls SAFE mode is bank/angle limits without self-leveling. Spektrum calls it SAFE "Envelope" mode. Spektrum's other SAFE mode is "Self-Level/Angle Demand". This is apparently Alex's "Level" mode.

Bummer as I was looking forward to try it in my pos plane

Great work Alex, Thanks for doing this great video John, So works with ER6, ER8. Will it work on any other RM RX's? You mentioned the option to solder on the ER8, if a person did that will outputs 7 and 8 be available, if yes is that an option on the ER6. You will need to do another video using your microscope and soldering directly to the board.

Any updates on this?

Did this project go dead? 9 months and no code changes or merges. Is there something new I'm missing?

Hi John, very informative and great vide, as usual!! So far I have found the following bugs: - Gain only works with the Rate mode, all other gyro modes seem to be at their max gain set in Gyro Gains in the Lua, and are unaffected by the master gain from the Gyro Inputs channel assigned. - Only input channels for which there is a possible pwm output, can be assigned to the Gyro inputs, for instance, for an ER6, only channels 1 through 4 are seen by the gyro for inputs, for an ER8, only channels 1 through 6 are seen for inputs, and so on. All the possible "virtual" channels up to 16 have no effect as inputs (for gain or mode) if they are beyond the channel number for which there are physical pwm output pins. So for an ER6, this only leaves 2 channels to use for model control if you want mode and gain inputs. The "Input Mapping" setting in the Lua always shows 5, and if it increased to more, like 8 or 16, it is reset upon rx power cycle. - The Min/Max pwm pulse width under the Model menu of the receiver wifi page doesn't only affect servo deflection for the gyro, it also sets the min/max deflection with the stick/knob/switch from the TX as well. So if a pwm servo, say ch2, or elevator, output is set to 1500 mid, and 1300 min and 1700 max in that menu, even if the gyro if off or centered and has no effect on the servo, the elevator servo will only deflect from 1300 to 1700 uS pwm pulse width, not its usual 988 to 2012 or what have you, so that setting acts as an end point adjustment rather than only for servo deflection commanded by the gyro. It is somewhat restrictive, and if it is left at its max, since the master gain has no effect on the gyro in level or any other mode other than Rate, the servos do slam all the way past their physical end points sometimes. So either that needs to be fixed, or the master gain needs to be fixed to work in all modes.

Hey John. It will be interesting if the vendors make the receivers with the gyro inside.

Nice walkthrough. Unfortunately, it does not appear to want to compile for my Happymodel EPW6. It is an ESP8266 based board, and from the looks of the errors, libraries are missing. Do you know if there are plans to support those receivers? It does work for my two EPS32 Rx'es. Thanks for putting this information 'out there'. Gordon

Yes! A new weekend project! 😅

I run my ELRS through a Radiolink BYME-A or BYME-D. I have the RX set up as SBUS . $22 for the Gyro plug and play ❤

Can you pass telemetry to a VTX? Maybe involve FC with Gyro? It will allow us to add GPS module for speed tracking, gyro data etc... Is it possible?

The Radionaster ER6 and ER8 have an extra dedicated -/+/Rx/Tx connection. Why can't this be used to connect to the gyro instead of losing 2 channels or soldering direct to the cpu? This output is a regular serial output as far as I can tell, I just configured it as sbus on my ER6 in the usual way and it works fine. It appears to work just the same as configuring 2 x pwm channels as one serial output.

great tutorial! very informative. BTW 1) gyro stablization is usually used with FC. I think the gyro here can be used for some RC planes without having a FC. Otherwise, what's the point of mounting a gyro (via i2c) to a receiver? BTW 2) Yeah somebody is gonna solder the gyro into a upcoming ELR receiver.

I'm curious about using this with RC cars, for directional stability. I've been searching around a bit, but I can't find a forum or CR where this is discussed. Any ideas where I should turn to get information to get started on that?

Is there any indication when gyro support will land in mainline ExpressLRS? Can't seem to find any info...

I do not have ELRS in my Boxer, can i use this gyro with a not ELRS radio and receiver ( question id for airplanes not drone)? Sorry if this is a stupid question but i do not know much about ELRS. Thanks

I like that little orange and gray plane tester model with the blue servos. Do you sell those or can you provide the .stl files to 3D print? I enjoy prototyping and testing almost as much as flying itself! :-)

Thanks!

So cool

So I did everything you did but when I go to flash I get an error saying this : Not a PlatformIO Project 'Platformio.ini' file has not been found in current working directory. To initialize new project please use 'platformio project init' command

I saw the Matek PWM converter has DA and CL pins, i suppose it can be use them for the gyro ?

Of course it does.

Why in the world does Radiomaster not make a gyro stabilizer receiver blows my mind!

This will make some people very happy ❤

Very good point that you show this gyro functions. But I was in touch with one guy developping this gyro mid november last year. He was very reactive and the progress went very fast (sometimes I had to test 3 versions in 1 day). But since severals weeks, it seems that there are no more activities on this subject. He told me that now the project should started to be officially supported by multiple devs, but no more news... I really hope this project is not forgotten, or with very low priority

Amazon is sold out! Can I get the giro anywhere else?
