We have versions in one, two, three and four rotor configurations.
Prototypes available now start at $10K for a single rotor. By 08/02 we
hope
to have pricing in the $<$2,500 range for the 530 with each additional
rotor
adding about 40% (i.e., 3-rotor would be $2,500 + (40%x$2,500) x 2) or
$4,500).

Boy wouldn't that be a dream come true.

How much HP per rotor can we expect Bruce?

These are water cooled engines with charge cooled rotors.
Roller or ball bearings throughout with lube oil mixed with the fuel.
The weights include magneto, intake system, carb and alternator/starter
apparently built into the flywheel. If so the alternator/starter is one
of the reasons for the high power to weight ratio and ideal for a hybrid
car. No exhaust system included.
The RPM's and HP ratings are very conservative for the displacements.
The engines are almost as large displacement wise as the Mazda.
For example a two rotor is 1066 cc while a two rotor Mazda 13B is 1300 cc.
If the anti wear coatings on the aluminum housings last, this should do in
the two cycle aircraft engine market once and forever.
Even if the BSFC is .55. (Freedom claims .4 to .5) The two cycle BSFC's
run .65 pounds of fuel per HP, per hour and they cost more.
The 4 rotor size is 26 by 11 by 11 inches.
If all this comes to past and the engine proves durable the promise
of the wankel engine will finally be fully realized.
Good bye and good riddance to the aircraft piston engine.
BTW Bruce, what kind of anti wear coatings are you using on the housings
both side and rotor?
