you can make this with Scotch Tough Duct Tape but use an transparent one.
its isn't remote controlled just in controls itself
Step 1: That You Need
you will need :
1 roll of duct tape
some wooden sticks
for the electronic:
1× 12v fan
1×9v battery holder
Step 2: Bottom
cut down four of the wooden sticks at 15 cm (5.9 inches).
then cut down 10 cm of the remained pieces.
Step 3: Front of the Boat
cut down 2×10cm of the wooden sticks.
then put it in triangle to the front side of the bottom plate like on the picture.
after stick them to each other and also stick the to the hole between them. if you did it stick the triangle(that you have made)to the bottom plate.
Step 4: The Sides
Step 5: Upper Front Side
this step is very similar to the third.
make that triangle twice.and stick it to the sticks that you left standing.
Step 6: Curcuit
grab the black wire and connect it to the switch' s first connector. the black wire of the fan is connected to the second connector of the switch.( look at the second picture to know witch is witch)
then place it into the boat
Step 7: Make It Waterproof
use an household film (like on the picture) to make it waterproof cover.cover the body of the boat. do not cover the fan !!!!
after you covered, fix it whit some duct tape.
