There’s an article on hackaday [h] about a model-builder who is trying to make an ultra-realistic model F-35.
And that’s my punch-line spoiled. It says:
[Joel] wants his model to be as close as possible to the real thing
How is he going to simulate 20 years of blown schedule mileposts, and cost overruns that make it cost $150 million per plane?
Joking aside, it’s quite an accomplishment. He’s got vertical take off/landing working as well as forward flight.
Another thing he’ll have to simulate: once he’s got it mostly working, he needs to put it away and build an F/A-18 or F-16. They’re better, anyway.
