Liftwood in Space 1889 was directional so you could reduce the
countergrav
effect to descend or land by tilting the panels. Which fitted well for
that
setting, not so much for a plausible future.

Hmm. Since it's a field, there's some kind of generator powering it.
(And
not just a couple of AA batteries - don't want to make it too easy.)  
Turning
down the power reduces the effect.
