Bought this motor to run as a back up to my Orion factory Team 5 port $399. Broke it in and never took it out. I run on a very large track and this thing keeps up with the high end Novas and O.S Speeds no problem. Doesn't get quite the fuel mileage as the higher end motors but in most cases 7-8 minutes is all you need.

The only reason I didnt give it five stars is that tuning wasnt as easy as other engines I have ran, other than that I run with O.S. modified losi's 454's and im still the guy to beat at my home track. I bought two of them with pipe combo put in truggy and buggy pipe on buggy power range works great truggy had to go with different pipe, but now it runs good considering I am comparing it to the .25 ROMA I couldnt get rebuild for. So overall not a Nova but not by much, and for the price this is a great buy. For those that cant seem to keep there finger out of the throttle this engine is great for running fast but not so fast that you lose it in corners or over correcting in the jumps.
