rudder on new HBK2 too sensitive

[minime]

Hi I've just fixed up a new HBK2 with head holding esky gyro and brushless motor. everything is nice n smooth except for the rudder control which is too sensitive. Just touch the rudder controls n the heli would be yawing alot as compared to last time.

Also at some point I don't seem to have control in the rudder at all.

What's happening???

stock tx or??

if computerised tx like the optic 6, reduce the EPA and put in some expo(-ve for hitech,fut. +ve for JR)

Hi john dyl, it's stock tx. It happened for the first time and I just switched to a head holding gyro. I suspect that would be the cause?? What's the gain for?

Is it the rudder link rod mounting position? For the servo end, use the outer most hole on the servo arm. And on the rudder control arm, use the outer most hole too.

gain is to adjust tail holding authority..

servo ball 1cm from the center? if u dont understand, it is best that u bring it down to a ff

Thanks for all your replies.

I have switched back to the original esky gyro and the problem seems to be gone. It's weird because when I had the esky head holding gyro on the HBK, the rudder is extra sensitive like when the rudder stick is tilted 15 degrees, the rudder would be fully tilted on the heli. If you know what I'm talking about.

I wanna know if it's due to 'gain' adjustment? or tx, receiver malfunction????

I can't even use the new gyro I paid for.

Sorry I can't join a ff due to work commitments. So this precious forum is all I got. thanks a dozen.

Is the servo arm drifting?
