hi matt,

and this is why I bought motorcalc, multiplex also has the electric calc 
program for 25 which does the same thing essentially.

BTW I suspect that prop you were mentioning, would switch to something 
smaller with less pitch(think pitches of 2-3.5 and 6-7" props)

and yes the motor does unload in the air and motorcalc takes that into 
effect.


sigh connectors just arrived from digikey.. BUT no wire/pins from mouser 
yet..
