This is the Lindberg Diesel Tug HO 1/87 scale kit. I built this little guy back in 94 while working in Minneapolis. While I was out there I had to make a few runs up to Duluth. It was there I took a few photo's of the Army Corp of Engineers tug. I then picked up the kit at a local hobby shop, and built her while away from home.

This guy is full RC and fully lighted. The entire cabin structure is scratch built to cut down on weight. The heavier plastic that come with the kit makes the tug top heavy, and would not be as stable. 

She ran of a servo motor which is really not as strong as I'd like. I installing a 400 direct drive motor with 4.8 volts. This little guy really has some power now. She has no problem push my Fitzgerald completely sideways.
