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 ground speed of 226KPH (140MPH), with a two-way peak average of 209KPH (130MPH). 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!

This is very clever. I'd love to here more. this group is very interested in things like this: https://m.facebook.com/groups/1551618814932503?ref=bookmarks please join us.

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..

Great build, super speeds. I'm looking to use similar components in my first Marmotte build did you have any issues at all, and more specifically the FC to ECS's? Also did you add a capacitor anywhere on the ESC's?
Thanks. The F4S FC (specifically V1.5) has been solid so far. I only added a 470uF 35V on one of the ESC power pads on the FC for 5S. The Tekko32 ESC was great until it died though. Probably because of all those speeds runs. Video was very clean.
