Gyro

A member of EAA Chapter 58, Doug B. is building a Super sky cycle.  The gyro-copter is a street legal, three wheel motorcycle that just happens to be able to fly.  Here are a bunch of pictures of his project.  A single rotor, Wankel engine powers the wheels in drive mode, while a Rotax 912 turns a pusher propeller in flying mode.





























Doug is also planning on doing some flight training in an old Benson gyro by towing it behind a truck.  He bought an old Benson and is planning on restoring it with new rotors, but no engine.

Hexatron

A couple of weeks ago, I went with EAA Chapter 23 to see the manufacturing of a small experimental aircraft engine, the Hexadyne P-60. 

The successful development of an aircraft engine is a difficult and complex task.  Hexatron appears to have done that.

Successfully (meaning profitably) marketing an aircraft engine is a miracle.  I don't think they are close to that yet, but I did enjoy seeing the factory.

And in case anyone from Hexatron Engineering reads this blog, I have some very helpful ideas on accomplishing the miracle part.  Please contact me through the comments section.
