A 'Gopro' camera was recently used to record the first Canadian rocket launch that delivered Canada's first rocket mail on October 31st, 2011.  Before launching I watched many videos with onboard cameras to see for myself what the best and most reliable method was.  What was consistent about most of them was that the camera pointed down and between two of the fins during the launch.  This caputured alot of exhaust at liftoff but really didn't give you a sense of the rockets true flight path.   My method of taping the high-definition 'gopro' camera securely to the center of the rocket using only black hockey tape (just above where the parachute seperates), while the lens was facing towards myself and the launch area is more visual to say the least. This method of a HD camera onboard the rocket captured a unique panaramic view of the area while easily tracing the flight path the rocket took from lift off to landing.  Watch the video on You Tube (First Canadian rocket mail flight 2011 by Ashley McIsaac) and you'll know what I mean

So the next time you record your rocket flight don't forget to face the lens towards you and not down at the ground.  Also remember, the center of gravity in rocketry is usually simply near the center of the rocket.  With this being said, uneven weight distribution at the center of gravity in a rocket makes little difference in effecting the overall balance of the launch vehicle.  So mounting a camera to one side of your rocket will make practicaly no difference at all and you should, and will have a normal predicted flight even though technically one side is much heavier than the other.  However, if you tried this same method but mounted the camera to the nose cone or closer to the fins and away from the center of gravity, the rocket would be substantially off balanced and the flight path would be compromised.  This can happen if you fail to recognize where the center of gravity is in your rocket.
