<DIV><FONT face=Arial>I measured V / A / rpm @ each different timing setting on
my test stand using the </FONT><FONT face=Arial>Eagle Tree data logger /
sensors. At least with the C50-14 Comp motor (21x14 prop), I observed no
significant difference in max A (+-1.5) / rpm (+-15) @ same volts (+-0.0)
between several measurements with timing @ 0 - 3 - 5 in varied order. There
could be temp differences (didn't measure), but likely small given A
are similar. </FONT><FONT face=Arial>So - 3 deg timing seems a reasonable
setting.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Logarithmical throttle response is much smoother than the
others - especially noticeable with higher C batts.</FONT></DIV>
