Tune PSC_ACCZ I mentioned before. Adding weight might help - all frequencies goes UP and LPF amplifies more.
Helloo guys, I checked with lower PSC_acc and putted D, D term just breaking drone, it vibrating like never so I took out D term and left lower PSC_ACC. In first look was not bad, but check out vibrations question with weight.. above 40 3rd gyro, first 150… thats crazy. and still on sharper moves its vibrating. So yeah basically nothing changed. I will put FC mouth because in this case i won’t let it to fly alone, imposible. Link is here : Download 2026-02-18 15-50-27.bin | LimeWire
Right, same frame you started this thread with 1 month ago.
so tell me exactly what to change i will change.
Hello my friends, I let X11 max to take a rest, didnt fixed arms vibration, so I decided to buy another motors, made another frame from full carbon fiber, I was thinking that is aluminium problem, I’ve bought a T-motor A12XL motors. Problemm is bigger viibration with this frame and motors. When i start to move to side or forward motors vibrating even more, looks like drone will lose control, tryed every all notch filter options, no luck. Looks like x11 max was even better than this. tryed to put lag as low as possible, filter was made on the lines. tested all ATT, tested Few PSC_ACC_Z and I. + REF, still no luck. I even put +5KG to frame, I tought that frame with batteries too light, but it was more painfull to watch than without weight, This larger file is best I could get to fly thru all day. Small size file is when i put some weight on it. I trusted in Carbon fiber, but i don’t see that is better than aluminium. Carbon arms thickness is 3mm.. Download 2026-05-05 15-18-40.bin | LimeWire
@xfacta @amilcarlucas @dkemxr @mike_tk , sorry guys for being rude for tag, but I really desperate. I need to fix this big drones problems in life or death scenario. Even esc telemetry working, maybe you have ideas is that better than throttle based ? I would love to see you help, and your opinion about everything.
Did you have RCoutput oscillation with the default Rate PID’s?
Yes, when I takeoff for first flight, it was oscillating, so I couldn’t lift it from the ground
5kg is nothing for this motors, your craft is too overpowered for this weight, hover throttle is near 0.1. What AUW is? Try add more weight, like 25 kg, it will move RPM higher so it can be filtered.
IMO 40% is good (which gives 60kg AUW)
Also one of the axes have much more noise, need to understand why.
My motors is 12-14s not these ones, today i will make a test in few hours, will put weight, and i will deop you a file
Voltage does not matter, only prop and motor size, the efficiency will be roughly the same.
