Sloth DD - X Class Quad

So after winning the 2020 X Class World Championship, I decided that I was going to build a quad variant to compete on larger tracks. My Octo is great but hits a speed wall pretty fast. This build looks to break through that barrier with ease.

Custom frame
Designing this was a major challenge. These 200a ADP ESC's are absolutely massive. I didn't want them hanging out or arm mounted, I wanted the tightest build I could get away with. The frame is double deckered (hence the Sloth DD name) with components on every level. The bottom plate holds the PDB, middle plate holds the FC on the bottom and ESC's on the top, and the top plate holds the Vista and RX. In my next iteration of this frame I will swap the PDB and FC for easier access. The arms are 15x11mm to start, but the best part is I can swap any size arm I want in to this frame. I fully expect the arms to snap like twigs, but this is racing, it's all or nothing.

Weight
This quad is no light weight, these motors are MASSIVE, the ESC's are MASSIVE, I'm running 8AWG wire to the batteries, and 10AWG everywhere else.
Resting without the props or batteries it's sitting at 2725g.
Batteries should add about 1600g and props another 180ish.
It'll be flying around the 4.5KG weight. Not light by any means, but the power it should have will be unreal. Each motor has the equivilent of 20HP. This is an 80HP quad. It will kill batteries as fast as I can buy them.

Batteries
I've picked up some of the new CNHL Race Series 5200mah packs to try out. I Also have a set of their Black Series 5000mah to try. This quad runs 12s, although it could run 14s. There are some rumblings of switching to super capacitors for these size quads, traditional Lipos are really holding us back so its only a matter of time.

Testing coming once all this snow dissapears!

Absolutely AWESOME! I can't imagine what it must be like to fly something like that.

FPV has had quite a journey. Just a few years ago we started racing drones around a track and doing flips over trees, but professional cinematic FPV is a more recent development. DJI has always owned the drone photography market, but smaller acrobatic drones are starting to enter the market. They have the advantage of close proximity flight indoors and around people. There's more artistic freedom and..

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..
