This size would also help explain the lettering for me.  With the idea of a fairly small size, I always had a hard time with so much lettering.  Now it makes more sense.  Think of the lettering on large military devices.
My guess is that no one who produced a model, thought they were this size.  This shows a lot in itself.
We at L E V I A T H A N were banned from the UFO Casebook Forum and it is so sad.

Just found this great tool that corrects "lens pincushion/barrel distortion, vignetting, chromatic aberration, and perspective" by using a camera database for calibration:

I wish I knew about this before, as the camera used for taking the calibration image used in my calculations is also supported. However, the corrected results differ only marginally (~ -1%) as only one reference point seems to be affected:

This is by far the best measurements analysis I've ever seen regarding the drones!!
Wonderful piece of work nekitamo!
Regarding the picture comparing the drone size to the human size, I have to say that first I thought the drone some meters small than that ;D
But, for the level of complexity (including the lettering), this size would do well IMO
