I wanted to build something light as Hyperlite Flossstyle, I once had. Since Covid-19 is disrupting global shipping I started looking within Europe. I knew about HaloRC quite a while and I actually wanted Osiris since it's release so I finally went for it. With Caddx Vista it's perfect fit even with 30x30 stack that I used.

The build was not difficult although the way the stack is mounted is not my favourite. I might have misunderstood it but Ok. The arms are 5mm and strong. I got 6" and they are hard to bend but when frame is put together it is kind of flexy. I had some serious hight throttle oscilations during maiden that I account to mounting my stack. So I re-did that. I also noticed that my motor screws were kind of loose so that is fixed as well. Let's hope that fixes the vibes.

I took some thingiverse antenna mounts and make them fit Osiris because I like my LR anttena verticaly - Halorc Osiris ImmortalT Vista antenna mount .
I also kind of remixed HaloRC Hero8 mount to fit my needs - HaloRc Osiris GoPro Stand

The old R9Mini I have was broken so I had to order new one. This time with OTA function.

The AUW is 625g with 1100mAh 5s and GoPro Session5 (in some TPU).
