Team Orion CRF 5 Port
 

Has any body tried one? Are they any good?

Yeah I liked it... it's got the power and speed like the other high end engines. It's been a long time since I ran it though. Cody King won the 2010 World Championship with it. I don't know if anything has changed, but Orion is Jared Tebo's and David Ronnefalk's engine sponser and they are fast with it, just as I'm sure they'd be with most other race engines.
