I've really been enjoying slow cruising lately with my other GPS enabled quads so I decided to build another one but with 7 inch props this time around. There aren't a lot of 7 inch frames but this one caught my eye since it has plenty of build space and it isn't over-priced for what you get.
I again used the Matek F722-SE F7 flight controller siince it has a barometer and plenty of UARTs. I already had a Holybro Tekko 32 4in1 ESC sitting around so I decided to use it for this build. It did require a bit of extra wiring to power the ESC from the flight controller but it was simple to hook up.
I drew up and printed the Hero 7 two piece mount, the flight camera mount, the GPS/Vtx antenna holder, the Immortal T mount and the motor wire guards. I found the arm guards/motor vibration dampeners on Thingiverse and printed those as well.
I recently ended up getting a bunch of the BrotherHobby Returner R6 2306-1660kv motors for a very low price and used some of them on this build.
The ViFly Finder 2 was taking up more space than I wanted so I separated the battery from the buzzer and mounted them next to each other.

How'd the 2306 motors work out for you? I find them very efficient on 5" props but wonder how they'd handle 6" or even 7" for longer range cruising... is the power/throttle curve decent or kinda weak on the bigger props?

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..
