Your not going to believe the thrust that Saito 450 puts out. I kept mine in the 6500-6800 range with a 22x10 prop and we clocked my 32lb Byron Corsair at 98mph in a low level pass. Also try to use a onboard glow system so you can run it rich, I failed to do that and after about 30 flights or so one of the cam gears let go, landed on 2 cylinders but I think it was from being lean so I wouldn't have to run an onboard, crazy thing was, I sent the motor in to Horizon for repair and they didn't have the parts to repair it so they sent me a brand new engine, really don't know if it was my fault or this was a problem with that motor, I never asked.
