To reiterate (that's a proper word right?) If you don't want your Hawk to climb, or DIVE if you are inverted, at full thrust, you will want a small P mix in your radio. So mount your turbine however you like, fly it, then mix to suit. The mix works great, I was surprised at how true it flies with that, it ends up being a very "clean" mix, you won't notice it when flying.
