I only use the max rate that I can achieve mechanically which is so high it looks stupid but it works! You lose a ton of efficiency with the ailerons being below the wing and the really high rates just makes the ailerons work as well as it does on my other planes. Control wise, its doesn't make the plane not too sensitive at all, just nicely controllable even at low speeds. With a breeze I almost hover mine in and touch down right in fronnt of me. This of course freaks out the other pilots watching because you are not supposed to do that with a war bird! [8D]
