Mike, don't remember anyone posting use of a lazer level. I use a digital
smart level (mounted to a 4 foot level) as it allows you to get both wings
exactly the same, even if you were mounting the wings on a hill, by simply
comparing the wing reading to the cabin floor and doing some math. If the
cabin floor is 0.0 then the wings are of course both just set at 1.0 If
the cabin is 1.0 down to the left then you set the left wing at 0.0 and the
right at 2.0 etc! <IF> you have the room I find the best place to do the
wing mounting is on the table with the fuselage turned 90* and weighted down
to keep flat on that 0.0 table you built it on. Then each wing is pegged in
place at the fuselage and the wings adjusted up or down using basement beam
adjustable posts. Turn the adjuster heads in/out until you get both wings
exactly 1* and then do your wing struts. This is also a good time to check
the angle of incidence of each wing to see if they are the same. On the
Rebel I always leave the attach fittings undersize, until the inital wing
fitting, as it allows for some minor adjustments in incident by offset
drilling the final holes (done by putting a plug in the exising undersize
hole and putting a new pilot hole in it). The Rebel/Elite/SR don't have the
"luxury" of adjustable attach bushings, like a Cessna does, to allow rigging
the aircraft after you find out it turns left or right in flight. Mind you,
now that the SR3500 has those 3/4"od x 5/8"id steel bushings on the front
attach fitting if you found a minor rigging problem you could get someone to
make you a set of offset bushing to replace them with.

Hi everyone,
I don't know the first thing about laser levels, but I thought I heard
someone mention that you could use one to measure and set the dihedral in
the wings. How do you go about doing that?
