At a point in take off roll rudder compensates for P Factor. Many planes do not have nose wheel steering. At lower speed, brakes keep the plane on center line to over come the P Factor.
On a high horse power turbine driven airplane such as the Pocket Rocket P Factor can be a real problem. There is not enough rudder authority to overcome the P Factor from that mill. Therefore punching full throttle on take off is usually not a good idea.
For a good simulation for this aircraft design you should have a hard time keeping it straight at full throttle on take off.
