After reading thru most of this thread, and trying to work out in my mind as
to how to do it...
After work I'm going home and rip apart my modified 8448, take the 8475
motors out of it, and throw on a znap prop on those motors and see what the
air flow's like.
Putting my current project on hold, I'll try and whip something together.
If it doesn't work, oh well. I am curious though, after reading these many
good ideas.
The only thing I have to formulate in my mind is how to get an enclosure
around the znap prop so that air doesn't escape up around it.
I'll see what transpires tonite!
