The Floss v2 is an older frame but I happen to acquire a huge collection of parts that includes 3 complete frames and a lot of spare arms (4 complete sets -16 arms). Since I just parted out my Rooster, now I have set of worry-free Blaster motors that is under warranty until the end of 2019.

This build was kind of simple and nothing fancy. I took whatever electronics I have hord over the last few months on RCG and Facebook. I wanted to build something that I am not afraid to crash and also have HD footage. Weight is not too much of a concern because I already reduced the weight from the GoPro 7 Black and the TPU mount (around 150g) because I am choosing not to use it. But instead, I will use a Caddx Tarsier. I was hoping to have a dry weight under 300g, but I knew that was not going to happen because of the heavy Hypetrain Blaster 2207 2450KV Motors that weighs 35g (38g with full length wires). So, if I went with 30g motors I would be close to hitting my 300g goal. To knock off a few more grames I could switch out the TBS Crossfire RX and TBS Unify VTX for the Nano RX and Pro32 Nano VTX. Also, the HeliNation Gigawatt ESC is basically the same as the Aikon AK32 4in1 ESC but with the added weight of the heatsink. I could have used the Aikon esc instead, but I wanted to keep the Talon and Gigawatt stack as a set.

The only problem I ran into was the stack was too high and the top plate will rest on top of the Caddx Tarsier board. I even mounted the Tarsier board upside down to lower the overall height. The easiest way to solve this problem is to switch the 20mm standoff to 25mm and it will give me the extra space I need. I usually like reducing the high of the top plate instead of raising it. Before doing this, I replace the heavy-duty battery strap with the freebie strap from RDQ (it’s still a good battery strap). By replacing the battery strap it did reduce the stack’s height but it was still not enough, so I end up switching to the 25mm standoffs.

This is not my first time using the Caddx Tarsier and my previous build was a slow flying quad, so I did not notice this problem until I flew the Floss. There is a huge difference in what you see through the FPV camera and the HD recorded video. The HD video is a lot narrower and the video also have you wanting to see more. For example, in the FPV video I am able to see the horizon when I am flying forward fast, but in the HD view all I see is the ground.

I had some VTX issues and finially got smart audio working. I was reading the diagram incorrectly and picked smart audio on the wrong UART. Here is my first video after getting the VTX working correctly:
