Name
L.I.F.E.kopter is the MK Project of ["SelectaT"]
L.I.F.E. stands for:
L (symbolizes the [http://en.wikipedia.org/wiki/Glider_(Conway's_Life) Glider] in Conway's Game of Life) I nverse F rame E xperience
... and of course for [http://en.wikipedia.org/wiki/Life life] and all around it!!!
Forethoughts
Based on the standard MK setup (FlightCtrl, BL-Ctrl 1.1 with hi-power MOSFETs)
I decided to try an inverse frame (propellers under the frame) for two main reasons:
- pushing props are supposed to be more effective than pulling props because nothing (no frame, in this case) is in the way of the streaming air - result: fewer swirls, higher efficiency, less noise (hopefully!)
- the frame ends (extended around rotors) can be used as rotor protection and feet at the same time (picture follows)
Apart from this, you can now use larger more UFO-like caps because there is more room on top of the frame

tested and flashed FlightCtrl, everything OK here too. And now for the frame...
