The main driving factor that motivated me to build another Floss is the efficiency of the XING 2208 2150kv motors with a 5s lipo and 5” props. Originally I purchased these motors for a Source One 7” (https://rotorbuilds.com/build/17366) build and it worked well but it never seems very efficient. I was using the same CNHL 1300mah / RDQ 1300mah 5s lipos I am using now, and it could never get more than 5 minutes of cruising flight time. Ever since I built a 5” Source One (https://rotorbuilds.com/build/23386) with these motors, I saw a huge improvement in performance and efficiency. So, I wanted to explore the potential in this setup. My next step would have been converting the analog 5” Source One to digital (https://rotorbuilds.com/build/23807) but I never maid it to the maiden flight. The only thing I did not finish was the DJI Air Unit Antenna mount, but I end up selling the frame because it was sold out everywhere and a friend of my wanted one. And that is how I ended up here with the XING 2208 2150kv motors in a Floss 2.0 frame. During my maiden flight I was able to get over 7 minutes of flight time with a mixture of high speed passes and slow cruising speeds. I need to double check the voltage reading on my OSD but it was still reading 17.8v (5s Lipo) when I came in to land.
More info and videos to come after I do more test flights.....

Looks like you have changed out the lens on the DJI camera. What do you think? Got video? I really liked the GoPro 2.5 lens back in the day. Seems like more cameras have specialized lenses now. I'm just about to maiden my first DJI FPV quad. Floss3.0 6" with the Air Unit. I would like to find a lens that gives me less distortion and the most light and quality.
I only changed the lens because I broke the stock one and the Runcam RC18G was the only lens avalible at the time. It was easy to install, I just watched a video on youtube on how to replace it. I am not sure if I suppose to remove the IR filter or not because the color looks a little off. The original lens does not have a IR filter on it because it is built in to the camera. Will it cause the color to be off if you have 2 IR filters? I am not to sure, but after replacing the lens it seems like it has a different tint when I compared the before and after videos.
Here is a video of the stock lens on a DJI Air Unit (was on FlexRC Ascent 3" quad):

I have not tried removing the IR filter to see if it makes a difference.
The stock lens looks better. The RC18G has a blue cast and doesn't show the red and yellow colors. That would make sense if you have two IR block filters in there.
This is the lens that I would want to try: https://shop.runcam.com/lens-runcam-swift-rr/
Or this one: https://shop.runcam.com/lens-for-runcam-micro-eagle-eagle-2-pro/
They both have bigger glass so should gather more light and help with night/evening flying.
I think you are right about gathering more light. Here is a quick test I just did. I removed the Foxeer lens of a Foxeer Cat Super Starlight (https://www.getfpv.com/foxeer-cat-super-starlight-low-light-fpv-camera.html) and compared it to the Runcam RC18G. The image quality is totally different. But I still do not like the color for either lens. I just sold all my analog stuff so this is all I have left.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

Man this is one clean build. Nice! Would you think other stacks would fit in there too or do you need a fc wit a flat back?
Thanks! I am sure there are other stacks out there that have similar profile but it is too bad the manufacture does not tell you the stack's hight. You can always use taller standoffs if your stack is too high.
