My ECO 7 worked very well until the pitch servo failed. Replacing the servo was fairly straightforward but readjusting the servo, as per page30 in the manual, is not. The instructions may have lost a little in translation but whatever I try doesn't work. If anyone has attempted this procedure successfully I would be vey grateful to know how it was done as my swashplate ring is now 1cm below the edge of the guide ring, not the required 1mm and the heli will not fly.
Very many thanks for any advice.

First off let me say I did not have to replace any servo. On my eco7 . This is what I would do. Slide out the assembly the with the servos and motor on it than unhook the servo arm Turn on the TX Than plug in the helicopter battery so the servo can center it self-sounds like your servo is turned all of the way to the forward pitch. Be careful not to hit the sticks on the radio. After with the power on put the servo arm on the servo. The servo should be at center Unplug the battery. Put the helicopter back together. This is my opinion. You make want to ask Ikarus.

I think that's what I should have done. Unfortunately I got involved with the reprogramming routine as laid down in the manual and now the original settings are lost. Think I'll just have to persevere with it.
