What I really hope for is that you PB make a buck out of it, you truly deserve it.

I am open to Tips / Advice so shout out.
Have considered putting re-flow oven together but turns out oven I picked up don't use Halogen which is preferred option and no budget to buy new one. Recycle is the route I'd go. Sure if I wait long enough one will turn up.
Maybe not to build one of these's but getting re-flow blower makes replacing Fets on ESC's a breeze and harvesting parts off dirt cheap pro minis cheaper than 1 atmega328 tqfp and you get all parts needed to run it afterwards, Bargain!! And replace a few locked avr's will soon recover your costs.

I am thoroughly impressed with the progress you guys have been making with the design, assembly and testing.
I am anxiously awaiting any news on the Universal Module.
Once again, hats off to you all!!

Since I didn't receive the non-working board in the mail, I was unable to debug any further. I've ordered 3 more boards with the fixes we found, and ordered new components. I am going to try to assemble the boards myself using a stencil and reflow. I have no experience doing so, so it'll probably be a catastrophic mess, but we'll see (I have all the equipment to do a good job, just no experience at it). Unfortunately, the fixes we discovered do not explain why the board SadSack assembled doesn't work, so we are no closer to solving that mystery.
I'll have everything in my hands in a couple weeks, and we'll go from there.

The boards are here:
oshpark.com/shared_projects/oyIOtWyZ
The Eagle design is here (note it is 4 layer, and probably can't be opened in free Eagle):
PhracturedBlue@bitbucket.org/SadSack/universaltx-4-layer
I haven't created the stencil mask yet. It is likely some of the pads will need to be tweaked for that. I'm going to use OshStencil for the stencils, and it should only take a couple days, so no risk.
The BOM is embedded in the Eagle (use 'run bom-xs' to get it), but here are the order details:

I also needed to order the stm32f072cbt6 from Arrow (Digikey has them on Backorder)
And I ordered most of the RF chips from AliExpress:
