Perfectly normal. When in acro mode (or any other mode other on ground servo cal), the triflight routines are running, and this is the system’s current guess as to where hover trim is.
When doing the on ground servo cal, these routines are bypassed so you can accurately set the min/neutral/max servo positions.
Then, when the in air servo cal is done, the hover trim point is measured and stored.9 March, 2019 at 21:30 #61261
I fly Multicopter since KK, from there i build and fly much more Copters with 3 to 8 Propellers and many different Boards and Firmwares 😉
But here i have a Problem:
Initial Setup etc is all done except Air Servo Cal dont save the calculated values. I did exacly the doings talked in Video, multiple times, but every time i hang Copter to PC “MotorThrustFactor” show only 13.8, every time. I testet to change the switch order but no other results.

1)Made the necessary setup steps to use the fdbk servo, disable the virtual servo and select ADC2 for fdbk in the triflight setup objects? (Assumes FDBK wire is connected to Rsi pad on KakuteF4)
2)Run the on-ground portion of the tail tune? Did it complete correctly?
Note that you must stay of the sticks as much as practical during the in air part because the algorithm is looking for trim, so if you are on the sticks, you are not in trim, and no data will be collected. It’s okay if the copter drifts around a bit.
In a perfect world, it will complete in a few seconds. In practice, I hover, staying off the sticks for as much as practical for about 30 seconds. Then land, disarm, exit tailtune, and value is saved.11 March, 2019 at 18:20 #61264
Hello! I was wondering if you guys have tried this on an f7 board(kakute f7). Also I followed the link for the down load… do click the down load button there??? I know it’s a silly question but I’m a noob..want make sure I going the right direction. Any help would be appreciated. I’ve been reading through the thread. Even watched David’s video…he moves fast in the first part of that video lol11 March, 2019 at 18:33 #61265
dRonin has not been ported to the F7 libraries, so no, it won’t work on the KakuteF7 (or any other F7) board.11 March, 2019 at 18:56 #61266
Ok,thanks for the quick reply13 March, 2019 at 00:52 #61275
yes, booth points are done exactly like in video descripted.
But yes, the hover flight dont comes to 30 seconds without touch the sticks. What David said in video let me think, dont steering to much but a lil bit is ok. Next time we have less wind (more than 50kmh since 2 weeks) i give it a try with copter fly away -> this setup has much power and a small not-perfekt angle result in fly away in few sesconds without touch sticks 😉
Thanks, i report results

I tried your wiring sugested for tricopter with Kakute F4 V2 – Dronin and it works. Thanks
GPS – return home
Could some one give me feedback on this for my configuration?: setup , tips, problems,…..
Thanks in advance

Unfortunately, the KakuteF4V2 does not have an external I2c port, so there’s no way to connect the magnetometer. The KakuteF4V2 AIO does if I recall correctly. I’ll check when I return home, been traveling for the last few days.16 March, 2019 at 16:25 #61293
Are you sure that the KakuteF4V2 does not have I2C-pads? I think it has the pads on the backside of the PCB. Please, have a look at the image attached…

Interesting, must have missed that somehow. Will look into how to set things up later in the week. I will have to modify the firmware to include the external mag routines. Great catch!16 March, 2019 at 17:06 #61296
Very cool, as I´m also very interested in a RTH solution!16 March, 2019 at 17:08 #61297
Wish I had my laptop with me…..19 March, 2019 at 10:29 #61302
I finally upgraded to the kakute and had some trouble getting things to work for linux, so for fellow linux users, here is what I had to do to get things working.
Clone jihlein’s repo and check out the mydronin branch
git clone [email protected]:jihlein/dronin.git
git checkout mydronin
-Werrorflag because I got a bunch of Qt errors (see https://github.com/d-ronin/dRonin/issues/2205 for details and https://github.com/rgorosito/dRonin/commit/9cdd97dff2d4b268f4f6d85f2a726ff3fbc42f1a for the fix)
Run make, it will show you a bunch of possible targets. The UI is called
gcsand it needs to be built.
It will probably tell you to run
make install_.... Follow the instructions and run
make gcsuntil it finnishes successfully.
build/ground/gcsshould now contain a
You also need to build the firmware hex file. Run
make ef_kakutef4v2. The hex file should show up in
After flashing, you may have trouble connecting to the board because aparently dronin doesn’t use the serial port. Follow these instructions to fix that https://dronin.org/docs/development-setup/development-setup-linux/#installing-udev-rules19 March, 2019 at 13:47 #61305
1)Finally got my Windows laptop to dual boot with Linux, can make Linux installers now too.
2)Added the capability to use CW props on the tail motor in triflight. Flight tested on my V4.
3)Added an LQG Horizon mode. Also flight tested on my V4.
4)Added support for external HMC5883 and HMC5983 magnetometers on KakuteF4V2, coded, not tested yet. I don’t have a convenient way to test this at the moment. Any volunteers? I can make a special installer for this purpose.
5)Some minor tweaks here and there to improve the robustness of the servo calibration procedure on both the tricopter and bicopter configurations.
None of this is available to general users quite yet. I want to get the external mag stuff on the KakuteF4V2 tested, then I will create new a new set of installers that include all of the above.
