the P-51 Merlin engine develops such huge horsepower, then delivering that HP into the prop as torque.  Takeoff becomes a lesson in rudder management.

From anecdotal experience watching firsthand a P-51 takeoff -- from memory from the pilot's words through the radio on takeoff:

"...[this beast has so much power]...[I have to maintain full left rudder on takeoff to compensate for torque]..."

I feel your pain. It's much more noticeable when pushing above 50 inches of manifold pressure on a dirt runway as with some of the Normandy airfields. I would make sure you set the 6 degrees of right rudder and two degrees nose heavy pitch trim and try some take offs at around 50 inches of MP. You'll want to do this from an airfield with a long, wide hard surfaced runway like Manston. What has helped me (definitely not perfected yet) is to make sure you hit LCtrl + Enter to turn on the graphic for your control positions. Make sure to keep the stick aft of center until you get to 100 MPH and then just relax it to neutral; lift off about 120 MPH. Keep increasing the MP by 5 inches or so as you improve until you can take off without issue at 61 inches of MP. This is definitely a work in progress for me.
