    I am studying this post with interest.
    Thank you for putting a lot of information in the post.

    I'm going to run a test using wifi rather than a radio module.

    If possible, can you share the source code of 'simtools game plugin' and 'rcrider app' you used?

    Wifi is likely going to add a lot of latency.

    Hey!! wow this is what i have wanted to do for ages!!

    I swear i searched a million times but i was obviously looking for the wrong keywords.
    This is awesome!! I have been looking into it lately and if you havcent heard of ExpressLRS well its a fairly new to the game transmission system that we are all using these days. It also has a firmware called Airport which sends telemetry data via mavlink or MSP to your computer using a secondary transmitter and reciever. with recievers being about 5 grams now it would be better suited to a mini whoop and do without the arduino and gyro and telemetry wifi module. Plus every flight controller on the market will be compatible with it as they all use the same messaging system
    see:
    https://www.expresslrs.org/software/airport/

    The flight controller (betaglight/inav) already puts out telemetry using MSP messages like MSP_RAW_IMU (9dof) and MSP_ATTITUDE. Wonder if there is a way to pull this data using a program like RCRider..

    https://github.com/betaflight/betaflight/blob/master/src/main/msp/msp_protocol.h

    Any thoughts? It's obviously way out of my expertise haha.

    Yeah I worked on this on and off over the years. What I found worked best for me in the aircraft was the head tracker from RCG and an immersion rc EZ UHF junior transmitter module and on the ground the receiver. I built a simple 3 dof miniature platform using 9 gram servos . The ezuhf is on 434mhz and I was using frsky on 2.4ghz. The motion was pitch roll and heave.
    I think you can use a plug in called joystick to run your actuators. Things get a little fuzzy here as it has been a few years.

    Oh thats actually a good solution too! I might try with this arduino code and get some interest with the betaflight/inav community and see if they want to help. Adding the extra wieght to planes or 5" quads wouldnt be muchy of a problem but when messing with toothpick style quads every gram counts.

    Does this work with Simtools V3? I tried to installing it but has warning that says, 'Could not load game plugin: RCRider_GamePlugin.dll'

    As far as I am aware companion apps are yet to be ported for v3, as this is the current v3 plugin supported list, but @yobuddy is the best person to confirm: https://simtools.us/plugin_library/

    Thanks for the info Noorbeast, no problem. Will wait but no rush at all...
    In Simtools V2 works though

    Got a bit problem, when I moved the imu and looking at RCRider.exe. I got good values, but in Simtools v2.6.1 in Tuning windows I'm getting values but without commas or dots. example, in RCRider a value is 15.750 but in Simtools getting 15750 (without a dot). I saw video in this thread, in the Tuning windows has both of them. Matches between RCRider and Simtools.

    Also, values are jumping around by itself even I didn't touch the BNO055 imu. Tried delay(250) got better result but after few second values are all over the place again.

    Can anybody know what is going on?

    Hi deeph,
    This sounds like a region problem to me.
    Do you use a coma or a period for the decimal point normally?
    If it's a coma, this should fix it I think.

    For a v3 version of RC Rider thou, I'm thinking of using an esp32 (with wifi built in) for a faster back-end.
    I'm hoping with a faster chip (240mhz vs 8mhz) and a faster backbone with wifi, we can get a good 100htz signal without much delay.

    I was also thinking of trying to use a dual core chip, and have one core sending the telemetry in a loop, and the other core allowing me to control the rc car from a pc cockpit (wheel and peddles). But I have not had any time to whip up some code for a test, so I'm not sure it will work yet. (But I have collected all the hardware shown in the pic below)

    Anyway, this is what I was playing with for a v3 version.
    When you have time, let me know what you think.
    Chat soon,

    Yup it was the region thing, comma showed up in Tuning Center, Thanks Yobuddy...

    Sounds awesome, I have that boards also. But btw why you didn't use BNO055 ?

    Is the BNO055 better? I honestly have not looked them over in a wile.

    I have tried Adafruit and the clone one, Adafruit has slightly better reading. But I only used BNO055 though, other than that haven't tried it myself.

    So, you will try with MPU6500?

    EDIT:
    or this maybe? https://www.adafruit.com/product/4754
