Limp home mode

Gentlepeople,

I am rather new to the list and normally I just lurk until I have something to say.  Well, in breaking with that mode I have some thoughts that I would like some opinions on so if youre game, here goes

1.      I am building a Cozy MKIV.  It uses an NACA scoop embedded in the belly to provide cooling air.  I am thinking of not building the NACA scoop as I plan to use some sort of Meredith effect scoop/plenum (ala the P-51) for cooling.  Thoughts?

2.      I plan to fly this plane on long flights over water (around the world is one of my goals.) Is there an ignition/injection system that provides some sort of limp home capability such as what is in the Cadillac Northstar systems that allows for intermittent firing of the rotors?  This to provide partial power in situations where I lose coolant overboard and hopefully, relying on oil cooling, continue to safety.  If not, what is the proper way to ensure redundancy of the cooling system?

3.      In reading several web sites regarding around the world travel, it appears that apart from endless bureaucracy and outrageous landing/handling fees, the largest problem is fuel availability.  Most parts of the world have no use for 100ll or appear to have never heard of it. (just kidding, it has to be specially ordered in many places and sometimes it is quite suspect.)  Is the rotary particular about the fuel used?  I am interested in the SCORE technology that John Deere came up with and would really love a diesel rotary in this regard.  Diesel/Jet A/Kerosene is available almost everywhere.

That is enough for now.  My brain hurts.
