[TowerTalk] Chain Drive Question

[Garland, James C. Dr.]

The chain drive on my rotor has stretched over the past two years and I need to remove a couple of links. I've never done this before, so don't know what's involved. I have a work platform on my tower, so I can remove the chain pretty easily, if I need to bring it into my workshop. Can somebody who has done this before give me any useful tips? Tnx.
