That sounds like too much fun! hovering at 1/2 throttle! My Vector 540 is a rocket with a 91FX but havent tried low level hovering yet. I am trying to take it way up and pulling into the hover position and it seems to respond well without any problems. Most times I am just having a ball with flinging this plane around. It responds lightning fast and crisp, sort of like a very precise sports car. Maybe has to do something with the strong airframe and wings.
