Are the HS-81's brand new? They have a habit of chattering around neutral after a while which can be er... postponed by spraying some tuner cleaner into the pot and exercising them for a bit. I learned this while flying RC Combat which is a much harder environment than sailplanes and gleaned the fix from the Hitec board on RC Groups.
If that isn't it, I'd vote for a freshly charged 5 cell pack being the problem-- if it's draied down a little, the problem might disappear.
