Josh, could you do a video about the opposite end of the spectrum: how to build and tune for the most efficient quad possible? I'd like to see what you would choose for a super long flight 5 in and 7 in build.

Id argue that the props flattening out was making it easier on the ESC since they were not biting the air as much on the top end there. Retry with stiffer props 😂

Also depends upon the weight of the quad compared to what it was before with the pid's, especially with high power to weight quads, the pid's can really vary a lot, normally an amount of TPA such as 70% at 1700 can be applied to smooth out that wobbling caused by the pids at top end of throttle ;)

The ONLY way I found mine to go that fast with your exact set up was using carbon by-blades, other wise the tri blades set up just drew too many amps causing the quad to flip out. The settings I had to work with was not so much pids or filters but the setting in the esc, ramp up and such but in the end I was successful, the video is on my channel. Hope that helps.

Yay that answers an unsolved mystery of mine. My quad freaked out upon takeoff just like that, but not on betaflight 3.5, only when i updated to 4.3. I guess my quad was too powerful for betaflight 4.3 defaults. On that note, I have never gotten 4.3 to fly as well as 3.5, which is kind of a bummer. I tried downgrading but 3.5 but it isnt in the software list anymore. I could probably find it on the web somewhere but its just that extra bit of hassle. I kind of wish they just left old versions in the configurator longer, but i know thats a hassle for them because the gui doesnt work with versions that old.

@JoshuaBardwell 10 ай бұрын

Sensored motors are not just for FOC. They are often used in ground vehicles where you need torque at low RPM.

@matthewmaxwell-burton4549 10 ай бұрын

@@JoshuaBardwell if it’s not a servo, you can’t get 100 torque a low rpm with synchronous motors. An inherent trait. Unless you use a vector control based system you have no finite control over torque as it is still coupled to flux thus speed. Moreover the motor is unstable till you reach the steady state rpm. I went a bit off topic but that’s why I’d love to see foc on drones. Part of my degree was control theory and motor control. When I hear PID I shudder when I hear pid, as the running gag is pid is the poor man’s choice and is never the solution (pid is only optimal with 0 delay, which isn’t possible) in our case sensorless is absolutely fine, if an arduino can do it… anyhow thanks for your insight, love your content btw
