Lee, finally got a chance tonight for a pull test. This engine was turning 8300 rpm on a 18/8 right out of the box. Within 3/4 gallon of break in mix it picked up an additional 200 rpm with an expected, additional, 100 rpm once seated.

For now @ 8500 rpm with the 18/8 it showed 15.5 lbs. of thrust. Once seated and the rpms top off it will get the 18/10 prop and there should be a significant increase in thrust. Joe
