If anyone is to attempt this, make sure you have a camera with auto
advance and which is able to fire in rapid sequence. Even in one second
the plane will travel 50 feet or so, and unless you can reach 1500 ft
altitude you may have too wide of a base. I've also heard that the small
engines create quite a vibration, so fast shutter speeds are required.

I've heard of this same idea using a big kite with cameras about 3 feet
apart. So you are looking at about 90 feet altitude if you believe in
the 1:30 rule. Aim the cameras downwind unless you want a self portrait.
