Oh, and I forgot push-pull-cables. They can be bad news, and heavy is the least of it. The more curves there in the housings, the more slop you'll have as they take up the space between cable and housing, and the friction is much higher than a pulley system. There's a very good reason why the vast majority of aircraft use pull-pull cables, and it's less friction and virtually no slop.
I have first hand experience on my "work project" for the last six years. A young engineer chose push-pull cables, and laying out on a table, they were "friction free". Install them, add a few curves, and it becomes a nightmare. And the higher load you put on them, the higher the friction goes. That doesn't really happen with pull-pull cables. We are changing back to what I recommended in the beginning...aircraft-type pull-pull cables. Granted, for straight, short cables, from stick to bellcrank, that'll probably work, and have the advantage of the ability to land if one side fails, but I don't know of a single KR (and very few other aircraft) that have had that problem. Give it a try though, and let us know how it works out. Mark Langford ML at N56ML.com http://www.n56ml.com
