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.
Alt Tag
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!

Awesome build! Any chance you would share 3D print files?

cool bro! I can't find anything on thingiverse for an AR8. Their search engine doesn't work that good.

OK, All parts are now on Thingiverse. They are under AR8 Drone Frame Components. There is a description of parts and the Stand offs that these parts where designed for in the summary. There were previously no other parts or items for the AR8 on Thingiverse, but there are now, so you should be able to get them all.

Thank you so much!!

nice creation.
1300 or 1700 kv motor?

they are the 1300 kv motors. If you are going to run 5s or 4s, then the 1700kv motors would probably be a better match

hey i have almost exactly the same setup -frame but ehat kind of flight tkmes are you getting on yriblades im only managing 5-7mins and i feel thats not

Pete_Air   Oct 17, 2019 

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.

ok thats pretty similar to me then i was hoping for more but at least im not an outlier

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.

Now THAT is a super clean build. A+.

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

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..
