Thanks for the comment. I'm not too sure about that because if you shrink to 70% you're most likely not going to be able to run the 5030 props. I did a measurement and you'd be able to fly 4" props with about 10mm of clearance between props. It's going to be pretty tight though. It does look like the Suppo A1510s do support a 4" prop as you can see here:
So it seems doable. Let me know what you decide to do. Would love to hear how this works out. I had to print it in two halves since my build plate wouldn't support a full print. Good luck!
