Hi Marv

Thanks, this is the way to go. I did read the plan a couple of times but
never thought of using the clear tube method to get it level.

Thanks this should make it a breeze. "Even Houdini can do this, and without
mirrors, :) "

HI Pine...

I just thought I'd check with you to see if you solved your leveling problem.
I would recommend you re-read step 5 in the manual (Chapter 3) where it
defines the process. The longerons are used to level the fuselage in the
roll axis.  The mark that you're looking for on the firewall is on the front
(engine side) not the inside where the nosegear tunnel is.  The water level
lets you establish the level plane from front to rear... there's a
drawing in the manual regarding the location of the aft mark which goes 5"
above the inside bottom of the rear of the fuselage, and placing one
end of the water level at that mark and the other end at the junction of
the + on the front of the firewall as I described earlier will get the
fuselage level from front to rear (in the pitch axis.)  

If you're not familiar with the water level concept it's really quite
simple... buy yourself about 25-30 feet of clear 3/8" or 1/2" hose.  
Fill it with water to within maybe 6-8" of each end.  You can take one
end of the hose and attach it someplace and then take the other end and
attach it someplace else... the water will be at the same level at both
ends of the hose.  Try to keep air bubbles out of it when you fill it,
as air bubbles will cause some inaccuracies with it as they are compressible
when compared to water.  The addition of a little bleach will soften the
water and make the level more sensitive.  I keep mine filled up all the
time and attached to my stub wings (on the outside of the BL 50 ribs) from
side to side to keep the fuselage level in the roll axis.  That has really
simplified doing the gear work.
