My V plus up until this point has been pretty quiet when I turn it on. Today I noticed that right after start up my gimble starts making a faint grinding sound. The camera stops just shy of its most upright position and grinds for a second before it finally kicks all the way up. When it does get all the way up the noise stops. I accidentally turned it on the other day with the gimble lock on. Anything I can do to fix this?
