63/91/120s because of the short end nut.</FONT></SPAN></DIV>
<DIV><SPAN class=118453003-02062003>The 813A is for 140s with long shaft
although it shows as short shaft. The outside nut is pretty long and
the inside one looks to be through the prop. So,
it looks like I need to bore the prop with larger OD of 813A
nut. (probably 11mm)</SPAN></DIV>

<DIV><SPAN class=287481903-02062003><FONT face=verdana>Those numbers are TT
adapter nuts. The APC props have different hub thickness depending on what
size prop you are using. Some TT spinners will not fully engage the backplate
if the prop hub is too thick....other TT spinners when tightened will distort
the spinner backplate.</FONT></SPAN></DIV>
<DIV><SPAN class=287481903-02062003>You can add washer shims in front of the
adapter nut to prevent the distorting and shorten the adaptor nut if the
spinner will not go on all the way. It's kinda goofy but that seems to be the
way it is. I asked a few other flyers about this problem a few years back but
they didn't seem to know what I was talking about.</SPAN></DIV>
<DIV><SPAN class=287481903-02062003>TT may make a short and long adaptor
nut....but I couldn't find it on their website.</SPAN></DIV>

<DIV>You may have the wrong threaded adapter nut. Check that out. I'm not
familiar with 813A, or 814A. What are these numbers. Been a while since I
bought adapters.</DIV>
<DIV> My 140l's run at full throttle about 1 1/4 to 1 1/3 needle
opening. That has a lot to do with nitro content. I run 30% heli fuel. I'm
guessing 2 turns out is a good starting place.</DIV>
