The Source One is a very easy frame to build on, and from all accounts seems to be plenty durable, which I definitely need.

My goal was to put together a reasonably priced yet durable 6s 5-inch quad. I feel like I achieved the reasonably priced part, however durability is still to be determined because it has been raining cats and dogs today. I did conformal coat, but I am not willing to risk it just yet.

There are really only a couple of challenges that I feel should be pointed out.

I used a large capacitor which sits on top of the VTX.. I'm not too keen on that, and it was a bit difficult to fit correctly. I worry that it might be broken by one of the battery straps.

The Mamba ESC has a strange layout to the solder pads. Each ESC has one solder pad on the outside of the standoff hole, and two on the inside. Its weird.

I had to VHB the receiver to the top of the flight controller, which I didn't want to do. Much rather have it stuck to the frame somewhere.

The Caddx Ratel Starlight doesn't come with a micro -> full size adapter. That set me back a few days.

There are a couple of things I would do differently in the next iteration of this build.

Get a purpose printed TPU part to attach the pigtail to that sits at an angle between the back standoffs.

Use a 30x30 VTX as there is PLENTY of room above the flight controller, and it would provide more space behind the stack for the capacitor, receiver, etc.

There is another mamba stack that is very similar, but with a 50a 4-in-1. The ESC has a more traditional layout for the solder pads, so I would probably pay the extra $10 or so for that one.

I am using the GoPro Hero 5 Black because I already have it. I may spring for the new Runcam Orange in order to shave off ~100g. Right now it sits at over 700g AUW which seems a bit portly.
