I have speedy bee, GEPRC, brave/lucid, and kiss ultra/voltara. Each of them have a purpose, but theyre all generally good at what they do. I use speedy bee for stuff like that, or did when it was in stock.
Whichever stack you can afford 2-3x of and reliably get that meet the motor/software requirements. (motor amperage for esc and probably like an F7)
Ohh thats the printed frame you were talking about, it does look impressive and the tests sounded good. Im still skeptical about anything printed with this geometry. This design structure really relies on that rigid carbon, you have to compensate with more complex geometry. Check out the aether frame if you havent already. But man do I want you to prove me wrong!
