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 ?
Rovao, my email address is [email protected]
I can email you photos as you like.
And I live in France. It’s easy to send via Colissimo International, no problem.
It should be at the center of the flight controller …
Do you carefully check and adjust the Center of Gravity ?
120 euros complete (motors, servos, PDB, KakuteF4V2, frame …)
I will sell it for a very good price 🙂
Thanks Erik, but I really don’t like this little bug…

CHAPTER 3: ATTRACTED WITH HELICOPTERS !
Planes were fun, but I was attracted with helis. More technical, outstanding flying possibilities…
So I decided to start with “something” that was not to small, widely known, overall good quality,an Align T-REX450
that I quickly sold for a flybarless T-REX 500. I LOVED to patiently assemble my heli !!!
Of course flying an heli is much more demanding than flying most planes, so I trained a lot at home with Phoenix RC to acquire some good reflexes and have a good feeling of helicopters behaviour.
I read a lot on HELIFREAK, and learned a lot from https://www.rchelicopterfun.com/ (many thanks to John Salt and his invaluable e-guides !!!)
After some weeks of training, I went to the field a saturday early morning, put my TREX500 on his skids middle of the runway, connected the 6S LIPO, pushed up the throttle cursor to spin up the rotor (pitch and throttle can be separated), nothing jerky, tail locked in … with the heart knocking I finally pushed up the left stick ! Holy Cow ! It was a revelation ! So easier to hover and do some basic flight than with the simulator. More stable !!!
Just to say, I was not interested for 3D. My idea was to learn to fly “scale” around the flying field with clean coordinated turns, and add a nice fuselage and some lights to my heli.
But, even if Learning flying it this was fantastic, I was not comfortable at all : I was scared of crashing it, and I was REAAAAALLY scared of the big spinning carbon blades !!! For me it was like playing with a running upsidedown lawnmower !!!
I sold it !
when I started with multirotors with a small quadcopter (I will post the story soon), I tried some firmwares and finally moved back to Betaflight, with the feeling to be “back home”.
And Betaflight can handle Tricopter perfectly, in my opinion.
Last weekend I assembled and tested the bicopter, but I’m not a fan of it. I will sell it now and concentrate back on my Tricopter LR.
The next step is to mount a french very perfomant FC, the YupiF7 (from the french Team CopperYu).
When satisfied Under Betaflight, I will migrate the YupiF7 to Inav to use it’s dedicated GPS ….
Whooooooo, what an exciting project !!!!
I can say the motors are not overheating, they are just warm … and both ESCs are still cold.
And both motors stop at the same time … Failsafe issue ??? I have to investigate 🙂
I will try to lower I and D on the different axis …
Hohoho first flight yesterday evening …
With default PIDs, unable to take off. Increasing wobbling of each servo …
I played a little bit with the PIDs, a now it flies !!!
Now I have to solve 2 issues:
– motors are a little bit hot
– It sometimes cuts power in the air and fall back to ground. I have to disarm / arm it to take off again. Any clue ?
