This gives me a thought for a test I will do as with a seaplane I can do things that
most will not do as I have runways all over there to hit. I can disconnect one
trailing plug and put a switch so that I can kill  one leading of my leading coils
to find out how it will fly with one dead rotor.

Interesting idea.  Let us know how it goes.


Another highly possible thing that can happen if apex seals fail in one rotor is
that they can get spit into the intake and get swallowed by the other rotor and take
it out also, this has happened to me many times with my off road race cars with
piston engines.

Using Paul's intake manifold, with intake pipes over to the plug side of the engine, it
seems to me that scenario would  be right up there with winning the lottery
(probability-wise).  Am I missing something?

What kind of intake system does Chuck have?

Here are some pictures of Chuck's system. A stone or a stray nut or bolt
could get in the system. Apex seal failures are extremely rare in
normally aspirated rotaries. As I recall Chuck no longer uses the
dynamic chamber configuration shown in the last picture.
It is now a simple plenum with bell mouths on the intake tubes.
