This all began looking for an X-Class frame that I loved. I couldn't. So I decided to CAD my own. Have it professionally fabricated. And build my first X-Class rig on my own frame. But no aluminum arms. No wood. Straight carbon. It turned into a more ambitious project than intended, with the original build-budget-cap planned at 700$....... Spent over half that on the frame lol... Oops...

Shoutout to CNC-MADNESS for cutting both revision-sets of 4mm body plates. Beautiful job.
The Revision-1 body plates had a design issues. The first discovered was the 2 rear-most standoffs are so close to the arms (.87mm) there's no wrapping a 3D-Printed mount around them. Solved with SMA mount under top-bolts.
The second issue found, and the biggest, was that the massive PDB did not fit between the center standoffs. Big mistake on my part. I now render electronics/parts/hardware into the design because of this.
HobbyCarbon cut/drilled, and supplied the 500mm arms, as well as the 2.5mm arm-bracer plates.
My good friends/FPV Buddies Phil & Matt have been working on my 3D-Printed prototypes/finals on and off for weeks now. 3 full sets so far.

Internal parts were easy. I've build 10 quads or so. I know what works for me & what I like/hate.
MOTORS & ESCs. This was the hardest decision. Budget? Gold? Original plan said budget. Quadlust took over. Also I was contacted by Demon Power Systems along the lines of.. "Hey that frame of yours would look great with our gear on it! Let us know if there's any way we can help get it completed!".. Long story short I ended up getting 110$ motors & 80$ ESCs.. Go hard or go home.

Starting this X-Class adventure on the tame end with 6S power on 700KV motors. Rated to move up to 8S when comfy. I know I know... X-Class's 12S is like the 5" Quad's 6S... I'm too afraid to start that way lol. Truly. Once I know I'm in for the long haul, my next custom frame will have a 565mm wingspan and run 10-12S XD

TITAN is a 1075mm monster!
The FRAME cost me 385$ after fabrication and hardware.

Very nice. I can see that the affliction of spending more on a quad than you planned is actually just a tendancy with us multi-rotor builders. What are the dimensions of those Demon motors? I also wondered what your wheelbase ended being. Thanks for the share!

DPS doesn't list the size of the Omen Series motors, but given the size they're surely 5xxx of some sort. The frame measures 1,075mm motor to motor!

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
