if i have the nose facing me with the cam pointing at me, phantom is off and with the polar pro nd filter on it...it completely falls forward and to the right. its takes 2 quarters and a penny on the back to keep it from falling forward. then it takes 2 quarters and a nickel on the left side to hold its balance. with this setup the motors did some screeching but it seemed to work. flew fine for those first 6 times or so then all the sudden take off and it wont hold cam in position. keeps automatically pointing the cam down then straight forward then back to where i had it set at. would do this every 30 secs or so.
so to remedy the situation i took the nd filter off, all the coins except a penny on the left side and that made it work fine again. but now i have wobble in my shots without the nd filter on it. i actually made a post in the phantom 2 section asking if there were more powerful gimbals to invest in so i could use the nd filter again. im worried that i screwed up the gimbal though flying it with all those coins on it.
