AR8 Free Range Ripper!

Finally got around to building a Long/Mid/Free Range set up. The frame is an AR8 from SCULPTCOPTER. It is an 8" frame, but I'm running 7" props on it, with a 6s battery and 2806.5 motors. I built it 5 mm lower than the standard configuration to get the CG as low as possible, so it was a pretty tight build and I had to design some shelves to mount the receiver and VTX.
I also designed a camera and gopro session mount along with some antenna mounts for the duel CROSSFIRE NANO diversity antennas.

Since GPS is mandatory for long/mid range, I designed a GPS mount that locates and orients the FOV for maximum clearance at cruising speeds.

AUW ended up being pretty hefty at about 1 kg with a 6s 2200 mah battery and GOPRO.

It's a heavy bird, but it flies super smooth and can do moderate freestyle. I've let it go 2 Kilometers so far and am still testing out props, but with the NANO diversity and GPS rescue mode, I'm pretty confident on letting it go farther!

I have tried three different Props (DAL, HQ 7X3, and KingKong 7040) and two different 6S size batteries (1500mah and 2200mah). The 2200mah last about 30-60 seconds longer, so I think I nearing the point of dimishing returns with the larger battery. I get about 6-9 minutes pending on how I fly. Full freestyle flight is about 6 minutes, cruzing with some Freestyle is about 7 minutes, and all cruzing = 8+ minutes. There is a video I posted of some flights. Those flights were all about 7.5 to 8.5 minutes.

You get top marks: componenet selection, orginazation, fitment, and visual impact. All 10/10.
You have made great strides in your 3-D printed part design. I feel like you still have some work to do there, you have a LOT of extra weight.
That being said, I imagine it's an amazing experience the way it is :)

Thanks for the comments! It was pretty fun developing this build. I have never flown a Kwad of this size and weight before, but it handles well and cruzes super fast. The 6s 2200mah battery alone is 380 grams, so I may try a lighter 4S and remove the arm guards to see how those numbers work out.

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..
