The Eurofox using the 912 rotax is liquid cooled and not subject to shock cooling like the Pawnee. After glider release and reducing the rpm to 4000rpm and a speed of 95knt decent rate for the Eurofox is around 2000ft/min.
Peter, yes I have been hiding behind a cloud of personal stuff that keeped me away from doing the stuff I like. The "cloud" as now dispersed and here I am.
