Once again, I am not surprising to see the quality of the frames designed by Catalyst Machineworks. They really think outside the box. As I was putting the frame together I kept thinking to myself “hey that is something different and what a great idea.” I have built a lot of different frames and this one I need a reference picture for me to assembly. I guess you can look at it as a good or bad thing because that means there are lots of different parts. Yet at the same time, these strange parts serve a purpose.

As you build this quad you have to plan a little differently. It is kind of has a modular setup because how the TPU pod houses everything except the ESC. It would be ideal if you used a 4in1 ESC and Flight Controller that uses the cable that you can unplug and not solder. I also stuffed the TBS Unify VTX in the pod, so hope there is enough air going inside it to keep it cool. After going through 3 packs back to back I did not have any issue with the VTX so I think I am in the clear.
For the first few flights I did not like how the Gemfan 5152 felt, nor did like the Dal Cyclone Cyclone 5046. But for some odd reason, I really like the Emax Avan – R 5x3. One thing I really like is how it has almost not prop wash. I guess the offset arms really do make a difference.

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays.
