The Typhoon is indeed looking good!
This is a frustrating issue I've found with nearly all FSX aircraft that have counter clockwise turning props when viewed from the cockpit.
(The exceptions are the RA Spitfire XIV, and the Flying Stations Sea Fury which behave as they should).
What happens (as John describes), is that the prop animation turns the correct way, but the FM pulls the same way (to the left), as if it was a clockwise turning prop like the Merlin (that's when viewed from the cockpit).
I've noticed that the Aircraft.cfg is always missing an important entry under the propeller section.
That is rotation = -1. (i.e. a counter clockwise rotation when viewed from the cockpit)
This is a very important parameter if you are to get the correct P-Factor (or pull to the right) reaction during takeoff and high angles of attack at slow speeds for such an engine.
But, if you add this line to the Aircraft.cfg for an FM that behaves as John describes, the FM now works as it should (pull to the right), but the prop animation becomes screwed (goes very slowly) and now turns the opposite way to what it should!
This is very frustrating for accuracy, and indeed for FM development, as if the prop animation of the MDL does not like rotation = -1 entry, you have put up with a prop that turns the correct way, but an FM that doesn't.
In FS9, you could fix this issue by adding the line prop_anim_ratio = (a positive number) to the [fltsim.xx] section, and it would work correctly for both the animation and the FM.
But as anyone who has tried this in FSX will tell you, it no longer works!
I would love to know from one of our modellers why this is the case with FSX, and why some prop animations do work with rotation = -1 entry, whilst others don't!

One issue, however, that I've found is that the p-factor/torque is pulling the aircraft in the wrong direction. From the cockpit, the prop on the Typhoon is spinning to the left, which should be creating p-factor and torque pulling the aircraft to the right (just like a Griffon Spitfire), but the flight dynamics are acting as if the prop is turning in the opposite/conventional direction to what it really is.
