It's fair to say I'm stepping out on a limb, but I am on the edge and that's where it happens.
-Max Cohen, Pi

This build certainly took longer than I intended. It didn't help that I moved on and completed some other very sweet rigs. I really tried to work out a very bomb-shaped canopy and tail combo that was sent to me by the Ryan @ QuadStarDrones, but my designer is a little tied up right now, and I left it as a possibility... so no biggie. This is the 6" ARX-R, but to drive the big 7" APC 7045's & V1S (or maybe some 6045, or 5260's... I'm gonna try 'em all) I made what might be considered an odd match. The Hyperlite 2207.5's are the highest RPM motor in their series, but I felt since the plan was to move more air, that a little higher torque might help. The 2208.5's are not much different than the '07.5's, but I also elected to take their highest KV option. I can turn the system down if need be, but big props and high RPM is the name of this bird's game. This is my last good shot at approaching Ryan's record (this year anyway), and so I figure I would get some nice electronics. A premium 6S Heli-Nation Talon GigaFusion Dual Gyro F7 Combo pumps the life under this hood with my second BF4 flash ever (required for the dual F7 setup). Stay tuned for my opinion. One really important thing to manage in an ARX-R build are the motor wires. They can really only be arranged in one fashion, but how to secure and protect? I got the idea that I could take one of those old thesis binder clips and cut it in sections and "clip" them onto the CF. That.... turned out nicer than any other hair-brained scheme I've come up with and I think I am gonna even start trying it out on "regular" style rigs. Ryan shot me the new corner braces he made to stiffen the ARX right before he shut down. They make the ARX feel like a solid-plate CF frame rigid.

I gotta give some props Ryan, through which all things ARX are made possible, CloudCraft (really?) for doing good work on the nylon canopy print + polish, and of course DWreck @ PyroDrone for shipping me these red V1S for my BLUE hex (lol... it all comes together; doesn't it?). This is the end of my season and so I just wanted to send out mad love to all of you toolshed and basement builders, freestyle-farm pilots who do cow prox work and rip barndos (lookin at you Reckless_FPV), and mountain + building divers. Your videos, pics, and build sheets keep me inspired to push the boundaries, build champion caliber rigs, and fly right.

Gorgeous! Especially that pod :)

Thanks! I gotta say that I am a little skittish at getting contract work done in PLA or ABS, but I always get really great results in the nylon. TPU is really expensive, so I decided to go this route. I am super happy.

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..
