All I can tell you is that mine had plenty of power, with good pull out from a hover, not a rocket, but it had plenty of authority, and was easy to get out of trouble. I ran my Saito with 15% or 30% (depending on if I was flying my heli that day, I just ran it on my heli fuel rather than bring 2 jugs out), and it worked great. My Saito had around 5 gallons or so through it when it went in the Showtime, and I probably put another 2 gallons on it in there before I got rid of the whole lot and moved up to a DA-50 in a Yak, and it always ran well and had plenty of power with that config.
