I struggle to get the second wing to fit, never knowing whether it's a bit
too
high or a bit too low. The ground is uneven and sloping, which doesn't
help.

I hope some Ventus owners can give me some tips, please?

A way to keep the first wing and the fuselage in alignment is really helpful. On my old PIK we glued a tapered spacer to the fuselage so that it held the spar at the right height relative to the fuselage opening. With that fixed and stable putting the second wing in was a snap.
If the fuselage won't support such a shim it could be glued to the bottom of the spar.
Shim should be just a little shorter than "perfect" so as not to create a bind.
