450 Heli vibration

Hi everybody!

I have a 450 Walkera with an APM 2.6 with 3.2.1 copter firmware. And I can fly it but it’s really hard. The copter vibrate a lot and there is too much expo in the roll/pitch commands. In the basic tuning menu if I change the value of roll/pitch sensitivity to the right the copter vibrate and it is not Possible to fly. And if I put it to the left the copter don’t really vibrate but I can’t handle it because I have no commands (if I put full pitch front on the radio the copter go really slow in front) like I have not enough course on the servo… sorry if It confuse to understand!

What can I do to increase the servo course and have not vibration?

The rotor speed is try with 2300rpm on idle-up1 and 3000rpm on idle-up 2 and it’s same thing…

Sorry for my bad language and thanks in advance for any help

David
