Re: [FlyRotary] 12A vs. 13B
I have this opportunity to obtain an RX-7
with a 12A aboard.
All the talk, research, and apparently flying aircraft seem to be
centered
around the 13B and 20B.
What difference is there in the 12A and is it suitable for aircraft
use?
Too heavy? Too wimpy? Can I turbocharge it? Or
should I just junque it?

I put about 150 hrs on my coot with
a 12a in it and was quite impressed with it, I had to turn it about
500 rpm higher than the 13b to put out about the same power but it
worked good.
I turned about 7000 rpm on takeoff
and 6500 for cruise which may seem high but I fly at 3000 lb gross
weight with this big bird.
Also the short 3 mm apex seals are
very durable and will take a lot of punishment.
