Hi Ozbecker
I too had problems understanding what is going on so I spent some time working it out. I hope this helps.
If you roll the wings with ailerons only, lets say to the right
1. the left aileron goes down increasing the lift on that wing
increase the lift - increase the induced drag
2.because this wing is producing more drag, it slows down and pulls the nose to the left( away from the turn)
3.because the lift force is now tilted, it is no longer opposing the weight force equally. The result of the two forces is that the aircraft slips into the turn.
4. as it slips into the turn, there is now a relative airflow striking the right hand side of the aircraft. this hits the fin and pushes the tail causing the aircraft to yaw to the right ( into the turn).
So you can see that adverse yaw happens first (during entry) then it yaws into the turn.
If left unchecked it would develop into a spiral dive.
