Designer Notes
The Hachidorii XL is Ricebowl’s take on a larger whoop frame that incorporates some characteristics from the Hachidorii XS and V2, such as the skeletalized frame to keep it lightweight, printed ducts for repairability, and toothpick-like construction that makes repairs and builds easy to do.
A Hachidorii Build Guide will be provided soon, alongside a build video for those of you who prefer to follow along with a video rather than reading a PDF guide.
The Hachidorii XL is more like an experimental platform, which people can play around with without worrying about weight or space limitations that the previous Hachidorii’s had. It also focuses on digital systems since this was Ricebowl’s first digital build, though you may also build it up as a traditional analog whoop with a TPU canopy - where, down the line, he does plan to make a vibrationally isolated mount for the Runcam Thumb Pro.
Outside of the carbon fiber components and the hardware included from CNCDrones, the following are needed to build up the Hachidorii XL:
1x 3D Printed Ducts [Files in Thingiverse/Printables]
1x 3D Printed Camera Plate [Files in Thingiverse/Printables]
1x TPU Camera Guard [Files in Thingiverse/Printables]
2x Power Chains or Elastic Bands [Such as https://tinyurl.com/3r6n4a6v]
1x 16mm by 16mm Silicon pad [Optional]
3x GEPRC Dampeners [Such as https://tinyurl.com/k2yj8k6f]
3x M1.4 Flange Screw [The ones you get on tinywhoops]
Some frame specs can be found in his video [https://tinyurl.com/555rmwcu], which discusses the frame in more detail. Additionally, there is an in-depth RotorBuilds article [https://tinyurl.com/55shpykj] which goes over some recommended parts, additional details, and his own goals for the Hachidorii XL. The Hachidorii XL can also be built in two configurations, which are the Top Mount (TM) and Bottom Mount (BM) variants. Characteristics such as flight performance and ducts in view are all shown in his video about the XL and all the components for both the TM and BM are included in the frame kit from CNCDrones, and the 3D printed components can be found in Ricebowl’s Thingiverse article [To be added] or in Printables [To be added]. Lastly, if you are curious about power chains, I have a short post about them here [https://tinyurl.com/4ha8smfa]
