RE: Will this still fly OK?
How much did you pay for that recorder?
It might be a good idea to make your red support into more of a box. Especially if you're going to fly over tall grass or such.
I know you only wanted to find out about the drag. But a guy at the field tried the same thing and his video recorder is out in the woods as we speak. Been there over a year.
Put a front and sides on the red support and it'll hold the recorder mechanically. Only need something to keep the recorder in. And that won't be very load bearing unless you do outside loops.
Sorry to spin off, but we've been looking for that guys recorder for a very long time. And he doesn't come out as much anymore since he has a low tolerance to kidding.
