  Dan,

In an accellerated spin is exactly as you described.  A pilot can increase
the rate of rotation by just pushing the stick forward when upright or
pulling the stick back when inverted. 

However; the increase in rate of rotation is only one of two changes that
happen during an accellerated spin.  The second is a decrease in pitch as the
rotation rate increases. 

You can simulate this by attatching a tennis ball to a string and a pencil.
Spin the tennis ball while holding the pencil. The faster you rotate the ball
the higher its swingplane will be. This is the same principal that occurs
during an accellerated spin. 

You need to reduce power, let go of the stick, and then add opposite rudder
just as Gene prescribes. The nose will lower and then the spin will stop. 

I will review the spin chapter and see if it is confusing. Does this help?

Thanks for the comments,

Michael
