Todd,
   The "Mistral" engine is not based on the Renesis but on the 89-91
13B to my knowledge........They now produce all parts (paper trail)
for the certified version of their engines so have been able to build
parts with out any of the compromises made by using stock Mazda
parts in their early experimental engines.......Therefore the new
production backplates wll not adapt to the stock Mazda 13B and
all early backplates were used on engines sold and a few were sold
to experimenters........I have never asked "Mistral" how many were
sold to guys like me..........FWIW

Is the Mistral engine based on the Renesis? And if so, is this plate still available for that application?

Since Ed seems to have so much info on that sweet new 1600cc rotary, maybe he can start working on an adapter for that one to add to his product line at AEE. Didn’t somebody on this list in years past build or attempt to build an adapter to mount around the stock engine which would bolt directly to the dynafocal mount? Or is just something that was discussed? I’m not sure it could be done without moving the engine ahead so far that CG would be an issue along with the necessity of substantial reworking of the stock cowl supplied with most kits…. which might be easier for many builders than building their own mount, since that seems to be a main stumbling block for many due to an inability to do structural welding. But many have mastered fiberglass by this stage in their kits.

 

Of coarse I do recall one builder that didn’t quite get the hang of the fiberglass, but he did learn to weld… J

      For your information I just received information that the "Mistral" backplate

(to allow use of Lycoming Dynafocal engine mount) that was adaptable to 86-91

Mazda front housings is no longer available (sadly 

 

Hi Kelly,

 

That's really too bad.  It was probably more expensive than anything I'd consider, but an affordable front cover replacement that would bolt to a dynafocal mount would really make the installation much easier.  It wouldn't likely be optimal, but I bet there's be a lot more people willing to try a rotary engine if it was that easy to bolt one one.  

 

Cheers,

Rusty (thinking about making one for the RV-3)
