Bill, on that Mylar Doll prop, is the prop spar line the line from point
to point of the blade ?
Also thanks for the info on the F1L - I looked in an old AMA rules book,
guess I'll have to check the current one online.

I like heavier prop shafts - usually .019 or .020 - just because they
hold up better to the beefy motors but .015 will work.
Your weights look okay if you don't go too much overboard on the
tailboom. LPP props can run from around .7g to 1g in my experience.
Bigger props usually seem to do better. The Mylar Doll prop is huge and
that plan is available on indoornews.com.
Rubber size depends on your prop, your flying technique.and what kind of
rubber you have. For really good rubber in low ceilings I'm usually in
the .095 range with loops around 16" long. For not so good rubber you
might do better with thicker and shorter motors. A smaller prop might do
better with thinner motors. Or if you like to do rafter banging a thinner
motor might do better.

Is .015 too thin for prop shafts on LPP. I have bent some pigtail
bearings out of .o2o and the .015 fits. Also where's a good starting
point for rubber? 10" motorstick. Wing weighs .65g, tail weighs .3?
motorstick not tail boom .95.
