How long is a piece of string?
Identified as a "An F-86 Sabre remote-controlled aircraft".
So it was probably one of these
Saw a video documentary once where a pack of c4 the size of a deck of cards was stashed on a grounded, discontinued airliner. The c4 blew the aircraft completely in half.
Don’t discount the payload that a large model airplane can carry. I have attended model airplane shows and have seen fly quite a number that could carry a 20 pound payload or more. It is no big deal to carry a tiny TV transmitter to give the “pilot” a bird’s eye view. And if you think the propeller models aren’t fast, you should see the little jets that can fly hundreds of miles per hour. Sweet! Technology has evolved to where any competent R/C hobbyist with a few thousand dollars could build a poor man’s cruise missile in his garage. Really, the only thing he lacks is a domestic source of C4, but our porous borders should not pose a problem. Right?
All of the others are Electirc Ducted Fans (EDF) and they move quite nicely but are barely capable of carrying more than their receiver, servos and battery! Other than the real deal, no significant payload..
