You are absolute correct, I for one hate fiberglass work, so tried to
minimize any cowl modifications. There was no after market anything (other
than the Lou Ross PSRU) for the rotary back then - nothing say like the
James Cowl for the rotary.
Most of the time was spent in technical trouble shooting and debugging these
two examples as they were the first (Tracy Crook) and second (Ed Anderson)
who successfully got their Mazda power aircraft to operating like a "real
airplane" {:>). No one to ask questions to or that had proven answers at
the time.
Another factor, was the cowl didn't signal anything unusual (engine wise)
under the cowl - until you fired up the engine. {:>)
Since I use two GM evaporator cores for my radiators - the two standard
openings provided an ideal place to put them. The cores cost me $5.00 from
the junk yard and another $30 each for having radiator bungs brazed to them.
So $70 did not seem bad for a radiator back then when a good custom made car
radiator seem out of sight.
The only substantial modification I made to the cowl - was to make a 22 sq
inch opening underneath the spinner for the Mazda RX-7 Oil cooler air intake
which I retrofitted after finding that the Earls oil cooler I had originally
installed simply did not do the job.
But, the rotary community has come a long ways since those days.
