Ahhh, camera platform. The SG6042 is only 10% thick which seems pretty thin to me, both from a structural standpoint and it's lifting capabilities. I used in on my gyrocopter rotor because it has less drag but similar lift when compared to the Clark Y and the lower drag caused the rotor rpm to increase and overall performance to be enhanced.

Seems to me that you would want a camera plane to fly very stably and slowly to help get good pics. There are some specialized weight lifting airfoils that may be what you want but just an old reliable NACA 2415 to 2418 should do a great job for you. My opinion only. One of the experts that frequent this venue will probably have a better suggestion for you.

Good luck and post some pics when your finished with it!
