Im gonna go ahead and solder the whole thing right onto the board without headers because I dont plan on making any other miniature quads anytime soon.
Besides, the extra size of having headers to keep it exchangeable doesn't weigh against the price of just buying another one anyway.
The thought of it squeezing right in between the plates intrigues me greatly though, havent thought about using it that way.
That would make my bash quad neigh indestructible and a lot more appealing to boot (and room for more leds!).
Damn you Wiseduck, stop planting expensive ideas in my head!
