Aberration,
Soloboss here one more time. I tossed a couple of posts at you and the second one is a bit misleading. When I noted that you may want to reduce the weight of the flybar, note that FIRST you have to get the helicopter flying really well. When it's settled and predictable and flies so steady that it's boring, THAT'S the time to remove the brass weights from the flybar boots.
Sorry for the ambiguous answer.
