Is the Camera making flying more difficult then it needs to be?

Even though the camera is extreamly light and small I wonder if the wind resistance and weight is throwing off the center of gravity just enough to make learning to fly more difficult then it needs to be.  On the maiden voyage we used the Flip Mino HD which is considered, "The world's smallest HD camcorder at just over 3 oz"  (3.3oz to be exact).  We actually attached a mirror to the front of the lens so we could have it lay underneath Rodrigos belly (fuselage) and still point forward.  Mino HD pictured below.

Recently, one of the main purposes and motivators of this project has been to get good areial footage to post, so having a HD/high resolution camera is important.  On the other hand, while learning to fly perhaps we should sacrifice just a little resolution (HD Mino 1280x720, RC Cam 640x480) just to get some experince with more actual flight time.  I have been reading about people adding weight to there RC airplane to offset the weight of added cameras or lights.  Perhaps there is more physics to this whole flying thing than we originally thought... who knew?

I will discuss with the board (brother) the possiblity of using a smaller camera for the next flight. 

I found this smaller camera below, weight 18 grams (approximatly .6 oz) online for $30 so I had to pick one up.  With only 7 days left, time is of the essence.
