Future of aviation, or flash in the pan??

I wonder if you had a plane with ballast bags, if that would make wing batteries easier.

Not sure if the wing structure expects such concentrated loads?

An interesting question.Â* How does the mass of the batteries compare to
that of water?Â* In my old LS-6a the water was held in bags which ran
from the root almost to the tip ahead of the spar.Â* They were drawn in
by a light rope and pulley system.Â* I would imagine that the battery
cells could be arranged in line, like a machine gun belt and pulled into
the wing thus distributing the load.Â* A lot would depend on the weight,
I suppose.

In my case the battery pack weight is 18kg and 1.5m long.

That mass in that distributed area is not that critical.
