Bill, Looking at a crank trigger as ultimate aim is alloy end
plates. Machining is simpler without the older distributor in
that regard. Neil.
Neil,
Depending on which year you have you can do this two ways.
If you have the distributor version (older) You can use any of
several simple electronic ignition boxes. Run a simple
collapsing field coil and a small plug gap. As a variant you
can use some of the aftermarket coil on plug coils. The
original Powersport ran a simple Mallory optically triggered
electronic ignition. Less than $80.00 at the auto parts store,
and the Mazda original Crank angle sensor. (distributor) No
high tension leads just a cap, and several multi-lead
motorcycle coils. As simple as it gets. You can also get crank
(eshaft) triggered basic electronic ignition. Or change over a
distributor type to a crank triggered if it has hall effect
pickups by doing your own trigger wheel.

Now I am
confused!! Let me start again and where I am coming from is
the everyday builder that may consider a rotary over a Lyc.
Price and time will dictate in most cases. Lets start with a
second
hand Lyc $30,000 That gives "wriggle room" on a rotary of
say $15 -
20,000 ready to go.
$10,000 for an redrive and ECU does not leave much especially
if it is a
single rotor.
I really like Lynn's suggestion of fixed ignition together
with a Rotec
carby, Carby $600 USD and fuel is mainly done together with
the ability
to control mixture via the carby.
THat leaves ignition NO matter how I look at it with any
sort of of
ECU it takes little to get to say $2000 -- if you have some
idea about
computers -- I don't!
What is actually necessary with a simple ignition? MY choice
in order
is Spark and timing. RPM, A/F ratio, Engine and oil temp
and
pressure , Battery voltage. Then whatever turns you on as
anything else
is not critical to flight or engine health. I realise that
the sky is
the limit here but all cost money to be balanced against the
Rotary vs
the Lyc.
Suggestions?? Remember I am computer illiterate. I prefer to
say I was
born too early rather than I am totally stupid!! Price will
sway people
to a rotary rather than "lovely" gadgetry that cost a lot of
money.
