Alright so I first did this mockup in early 2020, I'll leave the old frame renderings in there, but basically I took this quad to the X Class World Championship and won!
What you're seeing here now in the images is the 2021 version of my 2020 winning quad. The only difference I made has been really the frame. Trying to push it lighter and lighter.
Why Octo
Well I watched the Catalyst guys first put theirs together and tried to learn from them. No one else really runs this setup. There are good and bad points to it. First, she turns on a dime which is awesome, and second it much cheaper to build and repair. On the down side, it hits a speed barrier that will leave you behind on a big straight away for sure.
2021 Improvements
Basically I only changed the frame, reducing the number of bolts I needed to take apart to fix something, skinnier arms and my last upgrade will be connectors (My connectors melted off on my winning run). I would LOVE to find a lighter motor that can give me the same power, but everything seems heavier so I'm sticking with the iFlight combo for now. I think I blew 4 or 5 ESC's in 2020, none to smoke, they all died mysteriously. I can't say I'd recommend these iflight ESC's for the same money you can get APD, get the APD.
For props, the HQ's turned out to be super brittle. These MAS ones fit the bill perfect but I'd like to try some more in 2021.
This quad now sits at 1438g + batteries.

Love this build. Will I be able to buy the frame or a manual to build it? Would like to build a cheap x class.
I tried this esc-s too and constantly die one, switched to tekko 32 65A, and they works perfectly since a year with no issue. Great clean build btw!
grats on winning world championship!!!
your Iflight xing motors, what kv are they? I have 8- 2814-880kv motors and wanted to try a x class running 12s. I'm new to x class, dont really care to race I like the bigass foot print of x class drones and want one, lmao. your will definately be my muse in designing mine.
great build, ,i love it...
Congrats winning World Champ!
How are the motors wired? eight signal wires or one signal wire per each pair of motors?

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..

very nice I've spent about 8 hours researching on building the quietest drone possible at hovering and this is similar to what I was gonna design haha do you find this or the sx quieter at
