I have a holybro X500 v2 using a pixhawk 6c and i just finished the configuration proccess. At the time of test flight, when it is still on ground, it experiences a yaw movement impossible to govern.
The Pixhawk 6c firmware is: PX4 FMU V6C version 5, flash size 1966080
Can you share a log (upload it to logs.px4.io please and link here). You can record a log on ground by setting SDLOG_MODE to log from boot.
And you likely have to read about magnetic interference: Mounting a Compass (or GNSS/Compass) | PX4 Guide (main)
Hi , many thanks for your help. Tomorrow i’ll send you the log. In adittion i can say to you that on actuator control the 4 engines responds well to the test , and reached high rpm, but at the time of arming and up trottle stikc, the engines responses slowlly and with differents speeds between them.
On the other side , i have another question. , i am not sure if the program change the data at the time of finished every calibration page or i must press any botton for flashing the data to the FC, or this is automatic just passing the Pages.
Dear Julian, I have send you a file up load of my x500v2 holybro quadcopter. I have used exactly the GQC parameters of my model. I also have read your propousal for mounting a Compass but it seems that is not the problem.
Again once i flasher de Pix4/6C and trhottle up, the drone experiences an incontroller yaw movement.
I am very frustrated because I have been tried making a hover about 50 times, and its impossible. The log lines is about 1200 lines and i don´t know which ones could be failure.
I couldn´t sent the video

Dear Julian. I sent to you the onboard parametres file from my drone. I go on waiting your help because i can not calibrate my holybro x500v2. I have seen in this log (which is the QGC file for x500v2) surprising figures for some parametres. For instance, the geometry CA_rotor0_PX (and PY ) for the 4 motor appeared 1.0 m, which phisically is 0,18m.
Really i don´t know other parameters which could influence on the drone behaviour.
Many thanks in advance!
Anybody could sent me a file-log parameters for the holybro x500v2 with pixhak 6c which it goes well? THanks in advance
That’s a cool setup you have there!
Can you send me the log of that try? Otherwise, I have no idea what is going on. I’m referring to the .ulg file that is on the SD card after a flight, uploaded to logs.px4.io.
