Raising the entire airframe without the 400 + lbs of engine would be a
lot easier also.

Deems,
After talking with Russ Daves he was adamant about putting them on before you do the wings, why not prior to the engine? Datum line should not differ if the engine is on or off right?
IMHO

Deems-
Not many of us has data on this subject because once in place that is the way we fly - without experimenting toward improvement. Some thoughts:
The main leg fairing orientation seems to be important for rudder trim. Everytime I cycle them off/on the rudder trim needs adjustment. I have seen this three times. Note that the attach holes in the mating intersection fairings were never modified after initial install.
Another thought is during flight the main gear legs will have no weight and be positioned somewhat differently if the fairings are installed with all the weight
on the legs.
I have a hunch that getting the alignment perfect it is uncontrollable and only becomes important when you believe the necessary rudder trim has become excessive. The ball in my slip/skid is approx 1/4" in diameter and I needed to trim out half this diameter.

Well, the fairings attach to the gear legs, so sure, they change too.
On Page 48-4 Step 5 "Raise the airplane on jacks...."
So you do indeed jack the plane to do the fairings, and then you align
them along their "roll" axis so they align with the tire tread.
Then in future steps, you do the alignment just as you say, with
the weight off the gear. That way if there is any change in toe due
to the weight, you don't have to worry about it in flight. Nobody
cares if they're a little off on the ground, but in flight you'd
want them very very close.
So yep, do it without the weight on them. They just make that one
mention above on 48-4, but from that point on, the alignment is all
with weight off.
Note: This is one reason that most builders will want to consider
making up a pair of jackstands like I did on my tips page, because
you'll want them for when you get to the fairings if you have
the wings installed, and the jackstands are also extremely helpful
for other maintenance down the road. I just used them for
flipping my tires.

I know they spread but I meant does the alignment of the fairings change
(in regards to the centerline of the plane) with and without weight on
them?
If the alignment changes in reference to the centerline of the plane it
might be best to align the fairings with the weight off the gear.

Thanks Tim, that's the info I was looking for. Yes, I like your jackstand
idea.

IMHO the attached pictures show an ideal time/place/way to install the
fairings. Any time after this could work also, but it is nice to get them
out of the way early.
