Nice [8D]. Did you estimate your TSFC ? The sweet spot should be around 1.5 according to http://www.grc.nasa.gov/WWW/K-12/airplane/sfc.html and around 2.00 according to http://www.udel.edu/inst/jan2000/sti...ISE/sld003.htm ...
I guess it is much more than that ...
That night run is a great idea for sure [:-]
