Tom, the displacement is in the vertical plane only. I Increased the angle of the motor mount from 5 degrees to ten. It took care of a lot of the offset. I may try another couple of degrees. I made up a four cell AA battery box with the Astro Flight connector that I use for testing. All four cells are for testing with the speed control. I made a short circuit using a piece of aluminum tubing to run the motor only. It's very convenient.

Tom I may not make it to the lake today. Dan.
