The firewall is tilted to the right to give a little Right Hand thrust to counteract the torque of the prop.
The engine is offset to the Left Hand side of the firewall so the prop will come through the center of the cowl.
If the tank doesn't line up with the hole, there's nothing wrong with elongating the hole so the tanl will poke through as long as it doesn't interfere with the mounting holes.
I agree. Everything is moved to the left, so the FRONT of your engine winds up in the middle of the cowl, as a result of the' thrust angle'. The ARF manufacture got it right. Once a guy figures out WHY certain things are done the way they are, it will help him to know what to do in the future if he gets a plane that is NOT engineered properly. This is a good thing, and a good question to ask and understand. I love the Hurricane. Landing gear is a little close, but wish you well with it.
