some flybars have weights on them, that you can move inward toward the rotor shaft or outward toward the flybar paddles....its a lot more responsive as the weights are put inward. therefore if you are just learning how to hover and want a slow reacting heli, move the flybar weights as close to the flybar paddles as possible, ive also heard of people getting heaver flybar paddles (or adding weight) to make it easier to hover.
