Last night I read a well written article in contact magazine about a guy
that went against all your believes,and had a successful rotary conversion.
1) This guy had a water to oil exchanger in his oilpan.(said to bring the
oil temp down 20 degrees, and even the water temp went down.)
That's gone. One of the reasons we no longer believe in it.
2) Had three simple pressure compensated side draught carbs.( no need for
sophisticated fuel pumps,oscilloscopes ect.)
Those are gone. (Except for Finn) Not enough power.
Intake runners too short.
3) a Engine mounted from the oil pan.
That works. Not as well as I would like. I am shooting for automotive
vibration levels which is to say undetectable.
4)a Simple muffler.
That is gone. It worked fine. Tracy's was a bit too thin
and only lasted 600 hours or there about. Still works fine on
Dave Atkins airplane made from Inconel. Tracy is still trying new
mufflers.
Then the shock,.... this was written by Tracy Cook.
What went wrong with all these ideas, it all seemed to work well.
(it must be painful to have a newcomer to group and having to draw pictures
agian)
Thank's for the newsletter.
