@JohnDixson: I tried finding the PM settings under my profile but was unable to locate anything with regards to that. I enabled receive emails from administrators but I'm not sure that was the correct option. If you can direct me to the appropriate option editor I would greatly appreciate it.
@Lonewolf_50: yes the bias is set with TO procedures we have within rigging the flight controls, which i have since done, but my question was regarding how the bias could degrade over time with both main and tail rotor rigging still in check. The bias is set with hard pitch control links (elastomeric rod ends) so if cable tension or rig is not out, what would cause that?
There is no PM/email facility for new members: when the 'I'm new here' emoticon goes, then you'll have PM and email
