I suggest you buy a prop guard
What do you use to monitor the WiFi traffic?

The ATTINY441 is listed @ $1.65 on DK. I am thinking of an EFM8BB10 @$0.42.

I've never seen that chip. Though I dislike th 8051 ISA (it's what I first learned and coded in assembly when I was growing up), I would be more than happy to bury the hatchet... On that chip from a technical aspect, it looks as though the only concerns I would have is:
Not 5V tolerant, so it would have to be behind one of my voltage regulators, which means it wouldn't be able to control them.
