Thought I'd drop SHnPGIE a line and let you know how my project is coming.
I've made many changes since the last time I wrote you. I've changed
the mechanical cyclic mix to a hydraulic system to eliminate the slop I
was experiencing.
..........
Due to the suggestions of others knowledgeable in the field I removed the
two cylinder/two cycle engine and replaced it with an AiResearch
GTP30-67 APU engine. The turbine offers substantial safety margins
over the two stroke. It has automatic speed control and increased horse
power.
..........
The big problem is that it's slightly heavier and required the design of
right angle speed reduction gear box that pushed the weight of the project
way over the legal limit of 254 LBS. Although I'm disappointed at
the weight increase as I'm sure others will be, I feel much safer sitting
in front of a reliable turbine than an unproved two stroke.
I've attached several pix's of the modification to date. I hope that
anyone that had their heart set on an ultralight helicopter based on my
work, isn't too disappointed, but this is the life of an experimenter.
I now have an ultra heavy ultralight that my wife says, that if it doesn't
fly, will
end up in a museum.
