Stumbled across this in my wanderings. Sixty-five pounds all up. It still looks like they still have some testing to do. But it got my attention.

I have touched that engine and seen it run. it sounds great running and if tweaked properly it may be a neat alternative to the Rotax, but it isn't making enough power to fly even a gyrobee at this point, so for us it is still just a dream.

I think that motor is a single rotor Wankel type engine. If they come out with a 2 rotor version it would be really interesting.

Ron, that was my thought too, a wee bit weak. But it appears it's still in the development stages. Alas! We can only hope. :p
This is the company that I was talking about in a earlier post, they do make a larger engine, a 2 rotor 75 hp and this one holds a lot of potential. If the price can be brought down to a competiteve level with the Rotax it will be a major competitor because it has the realiability of a four stroke and the fuel consumption just a little more than a piston type four stroke and the weight comparisons of a two stroke and the reliability that is even better that a piston four stroke

There's a guy here in NW Florida who has a ducted fan gyro of his own design. His name is Richard Sohn. He's currently bench testing his own design of a single rotor from a Mazda engine(13B). His plans are to mount it on a Avid flyer which currently has a Subaru E81. He's currently developing 110 hp@7500rpm and using modified Rotax gearbox. The weight is 170 lbs. on the bench with radiator/starting/redrive. That's about the same weight as the Rotax 912. I'm keeping an eye on his progress. I was always interested in the Mazda rotary 13B engine for my RV-7 project. They are great engines for aviation and very efficient if set up properly. The Mazada racing enthusist can generate over 300 hp from these two-rotor 13B engines with a weight similar to a Lycoming 0-360(200hp).
