Its nice to see some real world numbers taken from a tach.

The statement made by a lot of flyers about their engine when they say "it screams!" doesn't really mean anything.
Yup, real world numbers are great. Any time I'm looking for numbers for an engine, I visit this forum:
http://www.rcuniverse.com/forum/forumid_173/tt.htm . There is a remarkable amount of information out there. I'd encourage anyone who has done some comparative runs to post their results.
