Hi All...ok...I am on my third P4 and everything works fine except I got that minor squeak in my gimbal when it first boots up and does the self check sequence...it nevers happens after that...even after picking craft up...moving around and listening real close as the gimbal maintains the camera angle. First one had firmware issues...second one OA never worked properly and firmware didn't want to update at all....with this latest P4 everything went smooth. I read that some people just deal with the squeak and have many flights with no issues... Is there any way that I could possibly fix this issue? Lube?? I have till May 12th to decide if I want to try another one... Any thoughts or ideas?? Thanks!!
