You’ll notice it’s not entirely symmetric, because the torque of a rotary engine makes it much easier to turn and spin with the propeller, not against it. You can also tune “allowed” moves to match the capability of a particular aircraft (and that’s why there is a whole series of these books that you can use interchangeably in any Allied-German pair: ...but some planes don’t have access to all the manoeuvres). I played this and remember the Allies Sopwith Camel had the right-hand J turn the other planes didn't because of the rotary torque.
