Ok, I haven’t tried the “normal” Frsky telemetry… (Does this normal telemetry work in your setup?)
I’m also using latest version of R9 Flex firmware (181228 - EU version) with a R9M module on a Horus X10S (Opentx 2.2.3) and a R9 receiver (also tried with an R9Slim+). I’ve used UARTS 1,3,4,5, and 6 with no luck.
Same cable is working good in other Pixhawk1 setup.
I’ll appreciate if you post any progress on this matter!
Thanks a lot!
Yes, the Yaapu telemetry works on my X4R with the Matek in the Convergence. I use the invertor cable as shown above.
You may want to look at the Radio forum on RC Groups where all the FrSky threads are posted. There may be an issue with telemetry on the flex release.
Cheers!
This is a really great thread. My wife gave me a convergence for Christmas and I’m pretty much done with the stock flight controller. It is not terrible, but there is so much that this thing could do that it does not. I just received my Matek flight controller the other day. And I am busy preparing to follow in your footsteps.
I use a FlySky radio and want to figure out how to get APM to receive iBus telemetry, but that’s really just a nice-to-have.
I will be posting my progress on my YouTube channel if you guys are interested. http://www.youtube.com/c/rhouse21rcphysics
Hi Rod,
Feel free to post here as well. My project is waiting for winter to end before I get to try some transitions and autonomous flight stuff. This time of year is a tough waiting game for us in the NorthEast US.
I don’t know anything about iBus telemetry…
I’m in the DC Metro area, so I’ve been able to sneak in a few flights in the decent spells between blizzards and polar vortexes. This platform has so much potential, but I’m discovering E-Flite under-engineered some things. I’m probably also going to 3D print a new payload pod to give me the option of adding some more gear, just because. 
I’ve done a few mods to the airframe already. Here are some links to some of my Convergence videos. I’m hinting about my FC mod plans, but haven’t spilled the beans on my channel yet. I’m also upgrading the stock ESCs to Castle DMR 30/40 units, adding a Caddx Turtle v2 for FPV & HD Video, TM radios, adding a 2nd DVR for OSD video recording and rewiring the aircraft to have beefier electrical connections to the ESCs. It’s gonna be fun!
Enjoy,

Hello
I am using f405-wing (around 15 flights) with arduplane 3.9.5 (plane is a glider with flaps)
My f405 firmware is from dec 2018, Do I need to install a newer one ?
My question looks very basic
Thanks
Hi,
You should be fine using Plane v3.9.5.
Cheers!
Greg, thawed out yet?looking forward to your experiences in transition and forward flight…(final params)
been flying mine stock with FPV and happy that I get decent flight times >8min (I use hover only for takeoff and landing…very short periods)…am about to convert to MatekF405Wing and Arduplane
Hi Henry,
Yes, we are thawed out now but I’m heading for Italy tomorrow so my testing will be on hold for three weeks. The long winter dampened my enthusiasm so I hope to get my R/C bug back when I return. Good luck on your conversion!
Ciao!
Hi Greg,our paths cross again,firstly enjoy Italy would there be enough room in the convergence for the M12L receiver with the matek F405 wing many thank’s in advance
Yes Patrick,Greg’s projects and documentation are just awesome
Hi Marty,
Thanks for the kind words! I don’t have the Convergence open right now so just looking at the photos it seems like using the R12L receiver would be a tight fit. You might be able to cut some of the foam cover away so that the usb port on the R12L faces outward and the telemetry plug stays inside going to the F405 FC. You could also cut away some of the square center foam that houses the cover mounting nut. Lastly, perhaps the R12L cover could be removed to make it smaller but I have never done this. It would be a “labor of love” experiment. 
Cheers!
thanks it is a project I fancy doing I could id really tight for space use my micro crossfire receiver but the M12L just works with ardupilot not to much of the falling down wine when in Italy
Just hovered my converted Convergence in my backyard…only issue is a +/- 30 deg heading yo-yo back and forth…any ideas what is causing that?
I am using the same compass/gps location and type as yours…no slop in tilt mechanics…tilt trimmed to 90deg/0deg with servo min/max when in QSTABLIZE/MANUAL and no yaw input…same pids as you posted
yaw control works fine…just oscillates back and forth at neutral
Hi Henry,
These are the parameters that you need to tune for your setup. I found it easiest to have a laptop nearby with Mission Planner telemetry connected on the Full Parameter List screen. You can then land the VTOL, while keeping it armed, and then just tweak (small change) one parameter and then go test hover. Repeat the process for P, I, and D parameters and try going in both directions.

Due to health reasons, I have suspended my hobby testing. I hope to get back to enjoying this great hobby some time this summer. Cheers!
sorry to hear of your health problem’s Greg,get well soon
Thanks…sorry for your health problems…
Got it dialed in much better…greatly increased YAW PIDs from the above file…Yaw P up to .6, I to .06, Filter to 10hz update rate…still a little heading wag but only a few degrees, occasionally…Q_LOITER is working well in the 15-20mph winds we are having here until late in the week, when I will try transitioning…
Henry,
Thanks for the update! On these vectored yaw models, it might be the best yaw performance you can get.
What APM version are you using now?
Cheers!
