Just disengage the gear a little. Then hold so the shaft is horizontal to the ground. You will find the heavier side of the blade. Very easy to check balance.
I tried that method first. Unfortunately, beat-frequency vibrations associated with differential rotor-speed flight-control were still visible in the video until I dynamically balanced each rotor. There must have been just enough drag on at least a couple of rotors to make that method not quite sensitive enough for carrying the cam. But then mine had a few hours on the clock by the time I got around to balancing it for on-board video - including a bit of 'cartwheel practice' while flying fast & low circuits at extreme bank-angles.
