@Eric-Katzfey Nevermind, I found the issue. In the voxl-px4.conf file, the RC value was somehow updated to SPEKTRUM. After changing the RC value back to GHST, the issue was resolved. Thank you so much for your support!

@Eric-Katzfey Thank you for your response. For Manual mode, I recalibrated the level horizon, accel, compass, and gyro. However, during the RC calibration, I noticed a small shift in the yaw when all the sticks are in their neutral positions. I’m unsure if this is contributing to the issue. I attempted to recalibrate it several times, but the yaw does not reset to the 0 position. Please find the attached screenshot for your reference: [image: 1732209517950-ca3710fa-d00c-4444-b9cf-2fe8d267f7f4-image-resized.png] . As you suggested, I tried flying in Altitude Hold mode, and the drone drifted in the direction where the yaw was shifted. Is there a way to fix the yaw offset?

@Zachary-Lowell-0 Thank you for letting me know. this is my first time working with a multi-cell battery and a smart charger. I will be careful not to connect multiple batteries at the same time.
