What is a jetcal?

Ive been reading UL magazines and flying Rotax for
16 years and have never heard of it. How can I make
one?

As far as EGTs are concerned, Ive come to prefer 1050
to 1125. Ive stop running them any hotter because it
seems to cook the carbon into very hard deposits in the
combustion chamber, and on the rings.
