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...: The first quad designed from the ground up withas 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.: 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!: 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. : 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.: Swapping CF rods to create a 4" Ü150 or 6" Ü220 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!Über Design Ü180-V2 by Eric Chang is licensed under a Creative Commons Attribution-NonCommercial 4.0 International License.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 Ü180, I'm hoping the FPV racing community will continue to iterate and push the sport forward!Rev1 - Initial Release- 8mm square pulltruded tubes --> 10mm round woven tubes- 5.5mm round pulltruded tubes --> 6mm round woven tubes- Reduced plastic connector height from 13mm to 10mm- Reversed male-female mating between CF rods and plastic connectors for higher plastic shear strength- Increased motor mounting screws from 2 to 4 with compatibility for non RCX motors- Through hole for access to bottom bearing for lubrication- Refined industrial designREV1 - INITIAL RELEASE: https://drive.google.com/file/d/0B71...ew?usp=sharing Support me and my work by buying carbon fiber tubing here:
