Hmmm.. this one is definitely kept on file for my future Europa project.
I don't know the travel in question, or the amount of free sheathed cable on
the end (before being affixed to the tunnel), but how about installing a
tube of a diameter to be able to slide over the end of the sheath, and
attached with some sort of hinge at the lever? This would effectively
prevent the cable from kinking , although allowing some flex. If the travel
is <3"", this sounds feasible, no?
Saving-My-Pennies-Pete,
Got my wife convinced, now it's just that Canadian cash!

Subject: Re: Throttle Cable Considerations
John, I am so sorry to hear of your accident. Even more so when the
accident was due to a mechanical malfunction or a design flaw. If it's any
consoliation, I had almost the same thing happen to me at about 18 months
and 80 hours of flying. On preflight engine run-up to 4000 rpm for a mag
check, everything seemed normal. However when I gave it full throttle for
take off, I couldn't get much more than 4500 rpm and my seat-of-the-pants
told me I wasn't getting the acceleration I was used to. I debated for a
second or two, but then aborted the takeoff. Upon further inspection I
found that only one of the throttle cables had kinked as you described.
The other cable was working normally. The kinked cable had to be replaced.
Like you, I think the design is faulty and prone to malfunctioning. At
some point in time, everyone is going to experience this problem as the
cables will accumulate rust, dirt, etc. If someone comes up with a fix,
please post it asap. Again John, I am so sorry for the damage to your
plane. Thank goodness you weren't hurt any worse than you were.
Regards,
Garry
