<DIV><FONT face=Arial size=2>My experience has been that the three blader
permits a more consistent, and slower OVERALL flight speed, all through the
sequence. I believe P factor is primarily a function of diameter and
pitch, and smaller diameter props have exhibited less "ruddering" at the SAME
APPROXIMATE maneuvering speeds.</FONT></DIV>
<DIV><FONT face=Arial size=2> Flying a slower speed makes me
work the rudder more; I don't think it's a function of the three blade
issue, because they are smaller diameter than the faster prop.</FONT></DIV>

<DIV><FONT face=Arial size=2>I don't know if it's always the same, but on the
few models that I've had with 3 blade setups, I've found that moving to the
3-blader tends to require a little more right thrust. I've discussed
this with Dave Lockhart and he thinks it may have more to do with the speed
you fly at and how the throttle is managed as to whether or not you will
detect any difference. I can easily believe that and it might just mean
that I have to refine my technique to get through corner pulls with less
P-factor effect. For now, a little more right thrust seems to help me
anyway.</FONT></DIV>
