If I were a millionaire, the first thing I would do is to find out how to build up a kit of an F-86 jet RC plane......I saw one once...it was just outright awesome flying...
;)
Plenty of them out there, especially with functioning RC jet engines.
However, look for videos of the scale B-52 (RIP) that made both a dramatic entrance upon and EXIT FROM the RC scene.
It was a thing of beauty, while it lasted.
