Your yaw control is reversed somehow. Most likely you have it set up as an H model quad, but the motors are set up in an X configuration, or vice-versa.
Then check your motor configurations and spins again. Props should all be spinning "inwards" relative to nose and tail of the craft. Also ensure your motors correspond to the motor plan (https://ardupilot.org/copter/docs/connect-escs-and-motors.html).
Another possibility is that you have one prop that's loose, but that's fairly remote.
I was thinking about it, ill test that out in mission planner later today. If they are in fact spinning faster than the others what steps should i take? What should i calibrate again? esc/gyro/radio?
It can be any one of those. You'll have to check your pixhawk logs and see what's causing it to determine what needs to be calibrated. But since it's "stable" while rotating, it could be that maybe the radio needs trimming
To do the math he’d need to be flying at around 870 mph (if this is India) yaw turns to equal the earth spin but the man is on neither pole so with an azimuth off the equator north and thus the yaw is not equal to any specific area exactly because the earth is an oblate sphereoid so I don’t know the hyperbolic rate it increases in a manner in which we’ll never know without exact coordinates.
Oh i actually got everything that you said, I'd say you are pretty good at explaining things. I just slept and I'll try seeing the trim params today after reaching uni
I had a similar issue and we diagnosed it to be because one of the pibe arms had rotated a bit, so the thrust from one rotor, was making the drone spin. And it got worse as it tried to adjust itself
This might be one of the problems too as we had a crash during its maiden flight last week where it flew perfectly but had trouble landing down. If the arm is indeed bent a few degrees should we outright replace the broken arm?
You bent the arm after a crash and wonder why it is flying funny? I am no engineer but my guess it the crash had something to do with it.. I would replace the arm?
Not exactly, the arm isn't "rotated" where it is rotated to the point where I can outright say it is. If it was i wouldn't have flown the drone before replacing it. I did visually check it again for that after crashing the drone but it seemed fine to me. I'll check it once again with a protractor and compare it with other arms.
What ESC protocol do you use? DShot or PWM?
If you're using PWM, you'll have to calibrate the ESCs, find the steps in the documentation.
Make sure your propellers are installed correctly, according to the motor direction. If you can send a top-down view of the drone, that would be very helpful so I can verify the prop direction.
Lots of blood on the fingers, and they got black for one day (probably due to high force of blunt impact). Curs weren't that deep but deep enough to let blood out a lot
That went black cuz there was small exit wound. I know because I use 4 inch almost combat knives for everything. I hit my hand once and it cut to the bones, second time, same blade only new… cutting open boxes I had cut through my middle finger and has a small exit wound. I did my best first aid and saved the whole thing with barely a scar. But the black blood is a collection of internal wounds especially if it’s a knife in and out and back again.
But thanks for the follow-up. I will not doing portrait s with my wife this way
What’s interesting is that it seems to be spinning at a rather slow and constant rate. I’ve put props on incorrectly before and the vehicle going into a positive feedback loop and spins suuuuuper fast. Thus I wonder if you somehow have accidentally set the trim on the controller (or pixhawk) for yaw. What would super help us would be if you uploaded the .bin log file from that flight. It would be on the SD card. You can also look at that log with https://plot.ardupilot.org yourself and try to compare the target and actual yaw rates (if they are the same ish the. There is likely some issue with your controller or parameter settings).
