Dude,
Kinda hard to explain but these things I found have helped during the Alpha phase.
1) ease up the throttle, (the torque and P factor modelling are viscious if you're not used to it).
2) a notch or two of flaps will help a lot.
3) Some people have found external view helps initially, (I guess coz you have more reference points to work with, ie edge of the runway, buildings, etc, so you know when you are drifting off the line of the runway)
4) I use the compass to keep my line correct, (note this is not the Gyro compass but the magnetic compass).
5) get the tail up as soon as you can, (this limits the effects of P factor and also lets the rudder have a greater effect)
6) Practice, Practice, Practice.
Spotcha in the Air
Almost fergot: the P factor is the difference in the amount of lift produced by the prop blades on the down stroke against the upstroke. When the propellor disc is tilted upwards the blade on the descent gets more "bite" into the air. This greates more lift, (or "pull"), on one side of the disc than the other. The imbalance causes the plane to yaw. The sooner you get the nose up the better.
P factor is also short for Pucker factor usually caused by fear, (you can guess what it is that puckers =)
