Rooster6"

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.

In betaflight you can tell it that you have rotated the fc 180 instead of remmapping the motors, gyro or acc may have issues if you dont set that. Not sure how you did it, happy flying looks great! Waiting on my rooster 😊

Thanks for hint. I will look into that. Remapping resources and telling FC that YAW axis is 180° worked for me.

I had the same problem with the press nuts. The flat head screws are just not strong enough to handle the force. But I just hammered them in.

Want to learn how to build an FPV rig? This guide will walk you through your first FPV freestyle build. These parts were hand-picked to balance cost and maximize performance. The TBS Source One is a popular frame for it's low cost, high quality carbon fiber. It's easy to work with and provides more than enough space for your electronics. We've got a 32bit 4-in-1 ESC to bring you the smoothest flights..

You've probably heard the term "Cinewhoop". Traditionally it's a 3" ducted quad capable of carrying a GoPro Hero7 Black at a low 10 degree angle. More recently the term "Cine" has been applied to a number of RTF quads ranging from 85mm to 3". They all focus on their HD capability, but none compare to the stabilization of Hypersmooth (only available on the Hero7 Black). This is what really offers that..
