Hi everyone, new to the forums here and had a question. Just got my P3A on Wednesday and installed a Gimbal Guard from RC Killers yesterday. After installing the guard I turned it on and started tilting it all around and noticed when the gimbal reaches it's limits it kind of makes a hum sound like it's struggling. So I'm curious if this is normal on a stock setup as I failed to do this type of test before I installed the gimbal guard. Thanks in advance!
