what_the?!,

I don't claim to be a expert in ducted fans. What I do know is that raeding this thread is making you sound like the arrogant , smart mouth and all of the other "nice" things that you have called everyone that has a different opinion than you. Everyone that you have blasted for disagreeing with you has givin so many people so much help in this forum encluding myself. Never have I seen any name calling ie."tool" out of any of them.

mr_matt, Terry Holston, grbaker, patf all go the extra mile to help newbys SAVE TIME AND MONEY by letting people know what has worked and has not worked for them during their many years of flying. I don't believe that you are the first to ask to question, "Are ducted fans producing the most thrust they possibly can"? I think the simple answer to that is yes. You arent going to fit a 7" fan in many jets and people realized that, so they developed the turbine. Good luck in your trials, when your done I'm sure matt will sell you a Jetcat!

By the way everyone that you have spoken to uses there real name here, no ones trying to hide.
