Aero Floss 2.1: RX-001 C Spec

This build is a Floss 2.1 with a custom aero canopy that I've designed. The canopy serves as a drag reduction aero device and impact structure. It is printed in PLA with 12% infill and 3 outer shells for good strength and tested to withstand at least 23KG without breaking. It currently reaches a max speed of 226KPH (140MPH). Dry weight: 320g AUW: 530g

A key design choice of this build is to run a top mount battery, as bottom mounts tend to kill the battery with hard landings. It coincidentally also leaves the CG of the quad directly above the front motors at full send AOA (80 degrees). The canopy design iterations are tested in CFD (virtual windtunnel) using SimScale. Measurements done by BN-180 GPS linked to Betaflight OSD.

The speed runs are about 30-60m off the ground to avoid random dogwalkers and low flying DJIs.

I'm not using the ARX frames as it's more interesting to design the aero bodywork myself! Feel free to contribute ideas that can make this go faster!

I REALLY like this build. "I'm not using the ARX frames as it's more interesting to design the aero bodywork myself!" I agree, much more rewarding! Doing your own thing is the best way to come up with new and exciting ideas - just like you did here :)

Update! Happymodel has released a new V2 Frame which uses a more durable plastic. The Happymodel Mobula7 is one of those rare treats to hit the micro scene. Countless models hit the market every month, but this one just happens to check all the boxes. It's a 2S brushless micro with a 75mm motor stance. It's slightly larger than the more traditional 65mm brushed micros, but it's still quite small...

The Flysky Nirvana is a very cool radio. It has two enlongated grips, a color touchscreen, module support, rear switches, an internal charger, and a retractable antenna. When you see it you either hate it or love it. From the tall display to the rainbow anodized look it's sure to catch some attention.
