I havn't done any flying since Sept. 2004 and rust is piling up . 
		
		
	
	
		
	
I booked a C-172 RG for the currency check this coming sunday and i just can't remember the prop control feel,that is how much pulling out or pushing in does it take to go through RPM changes like from TO about 2750 RPM to 2500 for climbing ,2300 cruising etc.also what is the RPM change for a full turn of the knob?
Thanks for help
