I am 73 years old, and engaged in a lot of hobbies, the most favorite one being making working model engines. I am lucky to have two sons who also follow my foot steps. I believe that my greatest achievement in my life is building and flying the "Comet". The Steam powered RC plane. An article about this was published in the Model Engineer Magazine Vol.194, No.4248, 27th May to 9th June 2005. This was followed by a 2HP vertical reversing column steam engine (#10) designed by Ray Hasbrouck, a 16 mm gauge locomotive Brazil, and many more steam and stirling engines. We build and fly RC planes, which I started in late 60's, and last year we were successful in building and flying our single seater plane, using a kit by the name Zigolo from Italy. Now I am interested in making a Hot Bulb Model Engine, and while searching for plans I came across a thread in this forum posted by Chuck. So, I became a member.!!
