Hi Tracy,
        I do not idle at 700 rpm for the same reasons you mentioned.  Sounds
like the PSRU gears or thrust bearing is loading and unloading between
power pulses and makes a noise that sounds like the gear box is
considering eating itself.  So I actually idle around 1400-1500 rpm, but
was going to extrapolate the timing to about 2 BTC at 1400 rpm.

I still kick my self for setting the timing wrong the time I did have
the prop off.  But, since I intend to do a complete inspection after the
40 hour point (10 more to go) including taking the prop off an shipping
back to Performance Props to get my protective sheating put on, that
will be the time to redo the timing at 5000 rpm.
