as tu résolu ton souci de Yaw ?
Sinon change tes valeurs de YAW:
P à 100
I à 10

CHAPTER 5: GREAT FLYING !
Building took some time, but the result was worth it. So nice flights !
Slow, peaceful, it needed with just a small amout of throttle. It handeld the wind very good. It could even catch thermals sometimes.
I really had many lovely zen evening flights with it
you have effectively to set the servo limits in Betaflight, not in your tx. Otherwise it can go beyond, as Betaflight can’t know the servo limits from the tx.
Servos limits in the tx will only keep the servo in those limits when orders come from you, not from the FC…
Ok. Just wanted to know if you fine tuned them a little bit …
Now I’m no more with Betaflight, but use the copter firmware integrated in the Graupner Falcon12 receiver, and surprisingly the same PIDs values work fine !
Very strange. It would be interessant to know if others have the same issue with those props …
Your LR seems to fly clean. Which PIDs settings do you use actually ?
It seems they broke at the same place ?`
What’s the brand ? Well known one ?
You will see that multirotors handle wind very good …
I often fly my Tricopter in my backyard too, even with serious wind. I flew a flybarless TREX500 some years ago, and handle wind was more complicated, even with the 3 gyro BEASTX module.
More specifically with a tricopter, I have the feeling that one can achieve more graceful flights, less “robotic” than a 4Xcopter.
And THIS tricopter is really well designed. And once folded, it needs only a small narrow place in a case.
The only improvement I personally would like, would be that the bottom plate would be shaped to receive the PDB and FC, instead of the top plate … David, if you add this “upgrade” bottom plate in your shop, I will immediately order one !
Anyway this TricopterLR is definitively an amazing and unique craft !
Flacke, in the motors tab you don’t have to use your TX.
You have to check the little button “Understand the risks” and then you can move the cursor up for each motor to see if the right one is spinning, and in the right direction.
For example cursor motor1: rear motor should spin up …
If not then write down which one is starting. Let’s suppose it’s motor 3, it means that it’s the output of your motor 3 that is actually linked to Betaflight motor 1.
Take a look in the CLI with ressources, to see which output is actually linked to motor 1. You now know the output name (A01, B03 …) that SHOULD be linked to your motor 3.
Do the same with the 2 other motors, and you will know which outputs name (A01, B02 ….) are linked to which motor position (1,2,3) in Betaflight.
Now you can change the links to have the right motor linked with the right output name.
Understood the idea ?
The way theluxembourgishguy indicated to swap motors is, in my opinion, the best one.
I suggest you to use the motors TAB in Betaflight configurator, and spin each motor one by one. So you will know which ones are wrong and which one to swap with which one.
Then if you type ressources in the CLI you will know to which output each motor is actually associated, and so you will know to which ressource you have to associate each motor to be ok
Waooh, very interesting…. but too advanced for me.
If my tricopter has a clean behaviour for my flight , motors noise regular, motors / ESCs stay cold, it’s ok for me 🙂
Jihlein, eventually the curve for YAW is normal for a tricopter … ? As the Yaw is not based on motors speed only (as it is for a quad), but it depends of the servo too. It’s an additional parameter for YAW, with tricopters … ?

CHAPTER 4: BACK TO PLANES, BUILDING AN OLD TIMER !
After solding my heli, I stopped RC hobby for a while, until I discovered “old timers” RC planes through Youtube videos of Cocklebarrow Farm meetings.
I was amazed by these old designs that seem to fly so well, peacefully, in the windy clear skies of England.
I decided to build one myself. That would remind me when I built my first trainer so many years ago. So I ordered a Ben Buckle kit: the Junior60.
Some days later I received a long and narrow box, with 2 plans and balsa sticks … Hobby knife, pins, wood glue and sanding paper, the construction could begin …
Jihlein, it’s very interesting. What is “step response” ? Can you explain ?
It should be at the center of the flight controller …
Do you carefully check and adjust the Center of Gravity ?
