My Posts This: Topic  Forum		Is it normal to get a vibration/wobble on the way to higher head rpm then on the way back down again ? it is just for a second or so then it disappears. It happens way before the heli lifts off. It seems fine when in hover etc

all helis wobble till the main blades straighten out

My Posts This: Topic  Forum		as the guys said different blade tightness usually is the reason,,

""then on the way back down again"",,, but I have to say as for myself I have never seen it happen on any Century 30/50s,,

something else you may want to check is that your Paddles are at equal lengths out on the Flybar,,
or maybe your setscrews that hold down the Flybar have loosen so the Flybar has moved a bit, I have had that happen once..
