Hi,

  Does anybody know how many aircrafts are flying with a 13B rotary
  engine?

  I know the list of rotary builders but I only count 11.

  Thanks!

  I don't really know. I keep hearing about another one about
  once a month I did not know about. My guess is about 100 Mazda based
world
  wide.  Some start flying and some stop flying.

  That does not count of course the  over 700  Alexander-Schleicher
  50 HP one rotor motor glider engines sold by Austro Engines.

  Nor does it count UAV rotary engines manufactured by several companies.

  We have about 1000 people on this list although I have not counted
  recently.

  Many flying are not on this list.

 I have listed well over 50 flying aircraft on the Rotary Roster web site,
 and I have not updated it in over a year.  There have been a few
additions
 since then.

Kevin,     I think Tracy Crook has sold over 350 of his PSRU drives.
Being that build times are so long this measures projects ready for an
engine more than the number flying. It does also demonstrate the number of
builders confident enough to put the money into a rotary.

There is a Mustang II with rotary engine in McKinney, TX. owned by Bob
Rogers. The following EAA web site tells the story:

Have not seen this one on any of the lists nor do I know if it is still
flying. Worth looking into though. The Mustang II with tapered and folding
wing will out-perform an RV-7. See: Mustangaero.com
