Attached I have included a few pictures of my new little tug. The hull was built in a couple hours out of cardboard from a recycled cereal box and CA. The hull measures about 9 inches by 3 inches. It was covered in Z-poxy and 2oz cloth. Power is supplied by a Graupner multispeed 140 and 8 AA batteries. Lots of work left to do but it has been fun to run in the bathtub.
Some of you may have followed the build so far over at RC Groups. I call it a Mud Puddle Boat.
Best regards

<Edit> the goal was to build a scratch built tug for under $100.00 U.S. If you purchase a used or inexpensice TX/RX I think it can be done but I still haven't tallied up the total cost.
