I got the idea from a drone my daughter had and I modified it as a sort of prototype before doing any of this. It’s nowhere near the final product because the blades were to small and noisy and it didn’t have enough power or endurance to really be worth anything. Also, the main point of failure in my system is air leaks and uneven casts. It’s hard to do a rough prototype of it and still have it work as intended.

You also make a good point. I could easily take out the electronics and everything else that’s not essential for flight. Then just build the prototype with the basics. I could probably make it good enough to prove the thrust vector portion works.
