R/C Paradox - a pair of radio controlled duck decoys

Step 3 Heat form the duck

The top of the submarine isn't completely flat like the bottom of the duck. To make the duck contour the submarine, I used a heat gun, to warm up the plastic, and pressed the submarine into place. You may need to hold the sub there until the plastic cools. different plastic have different memory properties, so you may need to exaggerate the indention to have it fit properly when it cools.
