 Thanks for taking the time to work on rotary engine conversions for
 aircraft,
 I, like you, believe it is the best engine out there for the job.  I have
 a Wittman Tailwind W8 with an O200.  When the engine needs overhauled Id
 like to have a rotary to go in it.  It seems like the Masda's may be to
 heavy wet for the application,  what are your thoughts?

 Yes it is too heavy for a direct replacement for the 100 HP O-200 but
 recently
 somebody has joined the news letter that is quite reasonable when it comes
 to
 making NC milled aluminum parts. His name is Jeff Doddridge.

 We have been kicking around a design for a relatively low cost front and
 rear rotor housing made from aluminum which would yield a 125 HP Mazda based
 one rotor engine competitive in weight to the 100 HP O-200.

 Here are some 3D's and a picture or two.

 Richard Sohn is also working on an aluminum version of a one rotor Mazda.

Put the full 2 rotor 13b on the Tailwind..  People are putting up to
O-360's on Tailwinds, with the O-320 being the engine of choice.  My
impression is that it's relatively easy to build a 13b which matches
the weight of an O-320..


Matt-

If you go that route we have plenty of installation layout dwgs.

We also have a new asymmetric motor plate allowing a cool side mounted rad.
