On my DA 50 the choke doesn't move freely at first. It has a tight spot in it. Once you get it moving it moves freely. I mounted a servo today for the choke and haven't finished mounting the nyrod connectors as of yet, but am concerned that the tight spot will be too much for the servo. Also thinking this is going to add to battery drain as well. Anyone else notice this and have any ideas on how to get it loosened up? I had read on an RCU thread that there is a ball type bearing in the mechanism that catches the choke and causes this. How do you remove, if possible, assuming this is true?
