    Do you have the drawing CD's? They will show you. In addition, there are several posts on this site about that very subject. Do a search and you will find them. Steve Pierce posted more than a few photos in one thread in particular.

    I am not sure if true, but read that if your trim is on top (short wing) your yoke points up, and if your trim is down on the side like a Super Cub, than your yoke points down. I looked at a plane a few years ago and it wasn't quite as nice up close as it looked in the pictures, I didn't buy it, it was a nice plane but needed covered and more work than I wanted to do. The owner emailed me pictures before I looked at it, I found them on my computer a few months ago, and I noticed the trim yoke was upside down, I guess it would be easy to make that mistake if you work on lots of Super Cubs and not many short wings. Here is the picture below, again this is upside down for a short wing, but correct for a Super Cub.

    Not only correct but very nice. Am I right or wrong about the trim up yoke up, trim down yoke down? Or is that bad info?

    That two pulley setup trim looks great, I bet you don't miss this one bit. I will modify it like yours when the little O-235 tires out and I put a bigger engine on it.

    If your jackscrew is upside down how does that affect flight trim?
