‹ber Design ‹180, the first openly available, 12.5:1 thrust ratio 5" frame!


I've been teasing this frame on Instagram and over in the RCX 2205 motor thread as well as flying it and showing it off at F3Expo. It's still a prototype frame but I think it's close enough to release to post some info about it now. Without further ado, I present the...

‹ber Design ‹180!
Just launched the ‹ber Design shop! Sign up to get notified when kits will be available!



- ‹ber easy: The first quad designed from the ground up with User Experience as a priority. Most easy to build quads compromise on performance. Most high performance quads compromise on user experience (advanced builds usually). This frame is nearly fastenerless with design features that allow you to assemble the quad easily using zip ties. Leave your allen wrench at home! Zip ties are light, intuitive to use, cheap, and strong. Hopefully (mechanical) repairs won't be so dreadful if swapping parts becomes simple.

- ‹ber cheap: This frame and its design will be openly available. CAD files are posted below so anyone can print or modify the parts to make their own frame! Total cost for me was only around $15 in parts. I may setup a store to sell pre-cut CF rods and SLS nylon or molded plastic parts so stay tuned!

- ‹ber light, ‹ber fast: Weighing in at only 60g, it's one of the lightest 5" frames on the market. It's also currently the only 5" quad with potential for an 12.5:1 thrust ratio (or more if you build it lighter) when paired with the Rotorgeeks 2205 2700kV motors and HQProp 5x4x3. Thrust data here courtesy of QuadMcFly.

- ‹ber strong: CF tubes create a super rigid frame without all the extra weight of solid CF plates. Since it's a tube, you also have more isotropic strength compared to CF plates which can break more easily in some planes than others. Tubes also present a lower profile during fast forward flight compared to CF plates to decrease air resistance.

- ‹ber flexible: Swapping CF rods to create a 4" ‹150 or 6" ‹220 will be a breeze with zip ties. Just snip off the old ties, swap the rods, and zip tie the frame back up. Pair this with bullet connectors and you have a truly modular quad!

Props (hah, get it?) to the Black Bolt team for really kickstarting the whole high thrust to weight ratio movement. With frames like the Shrike, XBR220, and hopefully the ‹180, I'm hoping the FPV racing community will continue to iterate and push the sport forward!

I'm hoping to get things done before the end of the month. Unfortunately it's getting cold around where I live so the iterative process will be slower since I won't be able to test fly it as frequently. Good news is that people who live in warmer areas might be able to add onto the design and iterate more quickly in my place.

Still debating whether or not to tool up for injection molded parts. It will certainly be way stronger this way but tooling cost will certainly be a pain to swallow unless there's sufficient demand. Maybe a low goal kickstarter will be the solution? We'll see!

I hope I can contribute to your design! It's awesome!
You should sell the parts or the frame. At least you will make some pocket money. There will not be chinese knock off. The chinese don't know about it. They copy popular frame, like the QAV210. They won't copie yours.

why are you using square tubing on the ends? Why not round? If you can't use round, then turn your square 90deg so you have better air flow.

Like the picture.


can't wait to build one!
