Is the new Mistral engine that is gonna be certified (hopefully) based

Mazda freak-out at this (or y'all just have a much better design?).

What will make the Mistral unique....or, in my very selfish way, not

unique and more adaptable to what I plan to have in my bird.  TIA.

All the best,

We tried for many months to convince Mazda to collaborate with us... but, to use your words, they freaked out in Hiroshima... or was it maybe in Detroit?  So,
we are now developing our own block.  The geometry is 13B based (are we going to go RENESIS-like?  We need to do some testing of the latter in typical
aviation cycle... and I am worried of potential problems restarting it in flight... but I may be wrong) but we have brought a number of mods to make it better
suited to aviation use than the 13B and we took out a number of unused features the 13B has that are just relics of previous models, or that have a purely
automobile use.  So, the answer is no, you won't be able to swap parts between Mazda's and Mistral's.

In a nutshell, our block will not be really better than Mazda (we aren't smarter and only have a tiny fraction of their development "muscle"), but it will be
better suited to aviation use.

Thanks for your good wishes,

I would not worry about restarting it in flight. Once you take off it will be plenty
warm enough to restart. If you let it cool completely it will also restart.
The problem is people pump the accelerator pedal if it does not start right
away and that floods it. If it does not start right away press the accelerator all
the way to the floor. This shuts off the injectors. If that does not work you 
now have a problem. Once we knew this we did not have any more problems 
in 7500 miles.

I am trying to convince Mazda to put a 12 volt block heater near the bottom
of the rotor housing to vaporize the raw fuel in case it floods.
