I was gonna buy a Blackout Mini H, but didn’t want to part with $150 and the long wait. So I cut some scrap 1/4 Polycarbonate sheet (lexan) with a reciprocating Skill saw with fine tooth blade and in about 20 minutes I had a super strong quad frame. Its incredibly strong but you could make this frame out of aluminum, kydex, carbon fiber, wood or whatever. Its so simple and replacement parts are just minutes away. And it flys so solid and fast despite its pudgy 550g weight w/o battery, I get about 8 minutes on a 1800mah 3s pack. 690g with the pack.
tip: mcmastercarr.com has 6×12 polycarbonate slabs and the Standoffs. And a few bolts and nuts from the hardware store. I threaded my spacers, but carr has threaded if you want or get these M3x35mm standoffs and this nylon bolt kit. Build cost is about $11.00 USD and 20 minutes of your time.
(note: you don’t need to make it wide like I did, 55mm inner line is enough)
