Update 4/5/20: Hover test and FPV maiden flight went great. I flashed the FC with Betaflight 4.1.5 and turned on RPM filtering. I left the default PIDs and rates for the maiden. I was very impressed with how it flies. Propwash was almost non-existent. This is the best flying kwad on defaults that I have ever tried. Im exited to see what a little tuning can do for it. First flight was on a 850 mah 4S battery, so I wasnt able to push it too hard. The next flight was on a 1500mah and it absolutely rips. Very fast and very responsive.

Weight is 324 grams with lipo strap & without battery.
Weight is 420 grams with 4S 850 mAh Turnigy battery.
Weight is 503 grams with 4S 1500 mAh RDQ battery.

This build was constructed entirely from parts out of the FPVCrate subscription.   (except for the receiver). The canopy is very finicky to get lined up with the mounts for the camera, otherwise the build was relatively straight forward. My solder joints on the ESC are terrible, so please ignore those. The ESC that arrived this week from the March box did have some issues. ESC #3 wasnt flashed properly and it caused me fits, until I figured that out. The sun is supposed to show up later today or tomorrow, so I hope to maiden it then. I will post an update after the maiden flight.

Can you tell me where to put the FrSky R-XSR? Diagram has the RX Port (right side) with a GND/5V where in what UARTs go S.Port and SBUS out?

Sure what do I have to lose only a little pride but everyone starts somewhere LOL!

I also built this quad with FPVcrate equipment, and I have only minor changes to your model. I agree that it has the best default PIDs. Clean build!

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

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..
