For clarification the twin engine does not require any special tools and or
fixtures it is a continuation of the single and very simple. We will put
together a video of a complete build from raw parts. This will demonstrate
the simplicity and minimal part count. It is very very important that the
early adopter projects go good and that initial results demonstrate the
advantages of our engine in aircraft. We have three airplanes coming here
from Sun N Fun for testing and factory support.

Thank you for your input and Stay Tuned

Eric,
I had contacted you directly in the past, you might remember - I'm a
dedicated bike rider and I was pleased as punch to see a rotary in a
motorcycle.
I would like to ask some questions on the single rotor, in relation to the
larger torque reversals of the single rotor and how their managed in your
application.

Prior experience with rotaries in Aviation application indicate that the 2
rotor is far smoother than the single rotor and requires only moderate
dampening against torsional vibrations. This is achieved by  approx 4 donut
type dampers ( softer the better) placed in a circle, out wide as is
physically possible.

There is however some confusion on the single rotor and how that's dampened.
My research suggests that the much larger torque reversals, require harder
dampening and should be more centrally located to restrict the larger
reversals.

Can you comment on this in relation to your research and developments.
