Dubro stuff is great (if you already know exactly how to use it). A lot of their stuff doesnt have instructions on how to install and when they do have instructions they are very vague. It would be great if they could include a little more detailed install info. I made a mistake yesterday installing the standard pull pull system on a rudder. After the fact I realized what I had done. If the directions had been a bit clearer I wouldnt have had that problem.
