Project Junco
It’s an open source printable brushless whoop frame – currently available in 65mm & 75mm, designed around standard whoop-sized brushless components.

Little bit of extra background - I wasn't initially planning on making any micro frames this year. I knew that after starting to ship the Raven in October, there wouldn't be enough time to design, prototype, & produce a finished frame by winter.. so I decided it'd be fun to design something to be printed & make it open source. Even so, getting it to this point took about a month longer than I'd planned for. Now that most of the legwork is done, I'm excited catch up on some other designs!
This is currently my 75mm Junco build. The powertrain isn't exactly up-to-date with today's trends - but I do really enjoy the convenience of 1S. I will eventually be changing the motors out for probably an 0803, and then the Beta F4 2S AIO.
Even with these little motors though, it's a fun indoor flier and much more efficient than the same setup in a 65mm frame :)
Notes:
Looking at the bottom you can see how I've hooked up the rubber bands - this is nice as (on each end) one band goes around the battery and one band stays down as padding. Keeps it from introducing vibes vs just wrapping it across the middle.
TBS and Rakonheli both make props (31mm & 40mm) with through-holes that can be mounted upside-down.

Lovely build!
What did you print it in?
what it the battery was top mounted oOooOooO. Cool buid dude!!
Will you sell prints of the frame directly off your site I would like one please to build with. What a beautiful frame! WELL DONE
Eventually, yes. But as it's still pretty early in development I'm going to wait until it's further along before I start selling it. Even though it's pretty clear that it's a project, there's a quality standard to reasonably expect when you pay for something & the Junco just isn't there yet! Also, my printers stay pretty busy between Raven production & new developments.
So, what I've done for now is made a printing service channel in our Discord server. We've got about 40 members and counting, so feel free to drop in and request a print. Otherwise you could take the model and upload to a printing service like shapeways & they'll be on Thingiverse soon as well, which has its own options for printing services :)
I edited the design to work with 16x16mm stacks and the old racerstar 1103 motors, is there any place to upload the version on your website?
Guides & Reviews
AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
