Yes,I am thinking seriously about K80E,but I'm not sure would it have enough thrust for my future projects.Since I am buying in February,P100 should be out and P80SE could drop in price or even P100.K80 is a great engine too,I saw it on the youtube and it flies very well.JetCats are of course, great engines.Hammers should be ok,too( German quality,and chrigui said that his RT 130 in T45 works OK) .
Andy,does K80 has 82N or 75N of thrust.Olivier said that he measured 75N on his test engine.

PS:I forgot to say something.Another jet that I would like to have at some point in the future is F86(the one for 80-120N turbines,not sure which manufacturer).
