Hi Martin.yep fair call. Like putting Porsche wheels on a kombi

Having said that it looks like the rf45-50 is a much better machine. Can be picked up new and the brackets fit to the same place for minimal conversion time later on... (I have an rf-25 in worse condition than yours lol) so my way of thinking is get it to work and upgrade the machine later thus I'm considering servo's.

Your setup looks great and for that price you can't go wrong. Well done.

Quick question since I see your from the U.S. The link you put up for servo motors doesn't compare apples to apples. I'm looking for about the same as you 500-600 oz/in. What's the equivalant in metric? I see a reference to everything but that in the Korean links you put up.
