Just got this email below updating me on the Rotron (by Parajet) low Hp
rotary engines. Thought it may be of interest.

Dear Brian Feeney,


Apparently they are reselling the AIXRO go kart engine from Germany.
That is the one Bear used to fly over Everest

Rotron Engines have now entered the durability test phase. Development over
the previous 12 months has been extensive and we now have two engines that
will be available in July this year. A 294cc single rotor 45hp engine and a
160cc single rotor 25hp engine. Each size of engine has been developed to
accommodate either a bespoke fuel injection system with auto altitude
compensation or a standard diaphragm carburettor.  Both the 294cc engine and
the 160cc engine blocks have been durability tested in our dynamometer test
cell for 400 hours. We are extremely pleased with the test results and
estimate TBO to be approx 400hours.

Over the following 3 months we will carry out durability tests in real life
applications for both engines and the new running gear...ie exhaust systems,
coolant radiator, starter motors, a range a re-drive ratios to suit
different propeller diameters and the fuel injection and onboard generator
system. We expect to learn a great deal over the following months and fine
tune the new running gear components ready for the official launch of the
Rotron Engine range in July 2009.
