Gimbal calibration Roll axis [need help]
Hi everyone, I am a newbie to gimbal and PID tuning. I am making a 2 axis gimbal for two cameras: a GoPro and a Flir thermal camera. For the ROLL, I am using the BGM 4108-130 motor and the PITCH motor is Ipower Gbm3506h-130t. The current power I set for Roll is 210 and Pitch is 150. The gimbal work when it on the ground. However, when I mounted on my drone and flew it, the ROLL axis acted strangely. The Roll motor does not hold the axis well. I suspected that when the wind hit it, the motor could not handle ???? I tried to increase the power but nothing was fixed. Anyone know how to fix it? I am using UBEC to get constant 12V. Simple BGC 32 bit controller board. my PID setting for Roll was P:17 I :0.12 D:30. The power for Roll was 210. Here is the video of the problem:
