I'm about ready to mount my main landing gear (Outback gear) hydraulic
cylinders.  In preparation, I made a wood block to test fit the cylinder and
make sure everything fits.

Wow!  Everything is tight in here.  It sits very close to the aileron
control tube.

Anyway, the manual states that the standoff block from the main spar should
be made from two 1/2" pieces and one 1/4" piece of phenolic.  Great, bought
some 1/2" phenolic.  When I use the 1-1/4" standoff, the hydraulic cylinder
is almost perfectly parallel to the main spar.  It looks like if I add
another 1/4" to it, I'll have it perfectly parallel to the main spar, so
1-1/2" total would work.  However, it looks like it would still work even if
not perfectly parallel.  The manual gives dimensions as typical, then
mentions finding the right size.  So should I go with the manual dimensions
or is it better that the cylinder be perfectly parallel?

Also, the manual has you place the aft phenolic piece first, then put the
spacer in place clamping across the whole assembly with something in place
to gap where the hydraulic cylinder goes.  Wouldn't it be easier to do the
standoff first and then put the aft phenolic piece in place or am I missing
something?  I assume you don't want the cylinder tight against the phenolic
so it moves freely?

Finally, any other advice for this part?

Thanks,
