size=2>Ideally you would twist the prop at several places to acheiv helical
pitch. In practice, this is entirely unnecessary. Twist once, as close to the
hub as practical, and that will work just fine. I see that Dave L added more
detail to the procedure.</FONT></SPAN></DIV>

<DIV><FONT face=Arial size=2>Just to see if I´ve understood,</FONT></DIV>
<DIV><FONT face=Arial size=2>I must twist the blade about 1-1/2" from the
root untill it reaches the 12" pitch?.</FONT></DIV>
<DIV><FONT face=Arial size=2>Or must I twist it progressively from the

<DIV><SPAN class=994295921-15112004><FONT face=Arial color=#0000ff
size=2>First you need a pitch gauge, and then a monokote hot air gun. For
this size prop, I actually use 2 heat guns, to warm the thick blade root.
You will probably have to apply heat for 30 ~ 60 seconds with two heat guns.
Warm the blade about 1-1/2" from the root, and twist the blade until it
cools. You will need something to prevent burning your hands, like a block
of wood that has a narrow hole in it. The blade can be restored to its
original shape by warming, if and when you need several tries to achieve the
dewsired pitch. It will take practice to keep from bending the blade along
its length, while just twisting it.</FONT></SPAN></DIV>

<DIV>So what 3 bladed prop would you use on an OS160FX? </DIV>
<DIV> </DIV>
<DIV>Any reason to think a bolly carbon prop is better than an APC on
this engine?</DIV>
