Underwater Video RC Submarine U-16 Micro Sub
Here is a tip that I'd like to share about the U-16: water residue from a tank, pond or stream can sometimes seize up the turning thruster. If this happens, don't assume it's broken. Put the sub to your ear and with the controller, move the thruster to the left or right. If you hear a hum, you're good. If not, you have problems. Run hot water on the back of the sub (in the hole where the thruster is located), then use a toothpick to move the white impeller. Then use the controls again to free it up And it may take a couple of times. You should then be back in action! Good luck and I hope this helps. You can try to get it at Graupner USA.
