Will I get a slower response if I move the linkage to the inner most hole on the servo arm for training purposes

Yes, but it will also alter your pitch curve. That may not be bad though because changing collective pitch to a lower rate may be helpful. I didn't find this necessary myself. I just added some 1/16" wheel collars to my flybar and that slowed response enough for me.

Did you mount them next to the ones that are already there or out twards the end?

hi...yes you will find it eaiser to control....just check to make sure your swashplate is level afterwards...it will make it not so touchy and better to control if youv never flown before... just make sure you have lots of room to fly...if you can hover well,,,,use a big area and take it up a bit...the higher it is the better chance you have to recover,,,most all my crashes were when it was close to the ground,,,a good gust of wind and $ ..but like i say,,,make sure you can hover good first.....if know ones ever told you,,,,hover tail in first,,get good at it,,,,then go to left side in,,,get good at that ,,then go right side in...get good at that....and only after your good at all 3,,,wait till a very calm day,,,no wind....get up to 15feet and try to hover nose in and get good at it.....always remember,,,,bring the tail back to you,,as in tail in....to recover...once you get that down then your ready to try forward flight....but always remember,,,,if you cant recover you cant fly....trying to move to quick in learning will only take you longer to learn and cost alot more...

I have done this to my Axe previously. You will likely need to adjust your pitch afterwards, so the message also reviews one method to review and adjust without the need for a pitch gauge.
