I got to hypetrain of Armattan Rooster. I wanted to appreciate the people who innovate by buying their product and not just a clone. I might buy a Reverb in the future aswell but let's get back to Rooster.

I opted for 6" version because I just like 6" more. I feel more confortable. I did not really had this thought out. I had some parts unsued (FlameF4, XSR eg.) in my shelf so it was a bit tricky to build for me. Especially the FlameF4 is bit hard to solder because the pads are small.

I think I must have missed something in Chris's build video because I did not managed to put the sunk nuts correctly and the carbon delaminated a bit. Some of the flat had bolts were not good and I had to replace them with steel ones. I still get bit of slop in arms when I pull really hard. I decided to leave it like that because I could not tighten the screws much harder. Other than that all went well.

I am not very happy with the antenna mounting solution. I would rather have them in similar position as on Reverb. I will also have to make my power leads longer because now it is bit difficult to mount my Xiaomi Yi. I am also bit bothered by the fact that I can not lower my fpv camera below the protective stand off. I guess I will have to learn to fly faster.

The build was harder then I expected. I was bit disappointed by the dry weight (385g) when I first saw it. I am not sure whether 4in1 esc would help to ease the build. May be a little but then I would have to place Matek VTX-HV elsewhere. Also the issue with bolts and delamitation did not help much to brighten my mood.

On the bright side: I decided to rotate FC 180° to have xt60 in the front as Armattan does it. Because of that I had to re-map the motors in BTFL which was a new experience for me and I am glad I managed that. The low profile copter looks really nice and sleek. Titanium shines and it flies (only hover tested).

I look forward flying it.

Notes: I checked the weight. AUW is 660g with Xiaomi Yi and 1500mAh 4s pack. That does not look that bad when compared to 667g of my MartianII 250 with same load. I have also pro-longered the power leads on xt60 so it does not interfere with HD cam.
