Lead video just for usability reference.....not a purchase reference.
Lead shot also high density, low volume

Agreed.....wheels could be used for added weight but will need counter
ballast since they will be either forward or aft of CG depending on nose or
tail wheel. Fairings good for weight.
Flat sheet lead could cover part of center section.

Yes, larger diameter wheels would help. I'm thinking they could be housed
in Northrop Gamma style fairings. The wheels could be heavy and the
fairings hold ballast, too.
Based on the 4+ lb gross weight that's flown with the stock wing (from a
paved runway), I'm thinking we may be looking at a 10+ lb plane. I'm
starting to wonder where we can put all that weight.

Any thoughts?

In this case, I'm more concerned with takeoff than landing. I don't
think we can get a heavily loaded Mini-Apprentice to take off on our
grass runway. It is hard enough as it is to get the plane to roll at its
light weight. I'm also concerned that, even with the east alders
removed, we won't have a clear path to depart after takeoff. But rolling
is the biggest problem.
I see two solutions. One is to go to another venue to make the loaded
flights. I've not been to the Chimicum field, yet, but while I've heard
it is windy there, they may have a smoother runway and more open flying
area. There are probably other fields in the area that have paved or
geotextile surfaces.
The other solution is to put down a smoother surface on our runway. We
decided not to go with a geotextile surface because of the cost, but I am
going to look at Home Depot to see what they might have in way of a
cheaper alternative. We don't need something that will last, and we
don't need it to be wide enough to land on. It just needs to be
something we can put down for loaded takeoffs and then pack up at the end
of the day.
Cheers,
Tom

Tom,
Don't have runway envy. Tarmac runways do much more damage on a rough
landing than grass!

It's clear we will need provision for a lot more weight than will fit
inside the wing. Probably a ballast box like they have, and maybe some
ballast boxes out on the wings, too. I'm thinking Northrop Gamma style
wheel pants that come down from where the tail booms mount.
Cheers,
