1/3-1/2 depending on your prop. But Gjeffers is right I meant not to go full boogy in the horizontal. It would look great for a second or two, then it will look like an exploding balloon. The 91 will give you the ability to swing that big low pitch prop which will let you pull out of your hover with acceleration and unlimited vert. Have fun with it................
