hovercrafts are very interesting vehicles bcz its run both on ground and water.i also like them very much.so i m going to make a hovercraft at home.i used computer motor as lifting fan and 2 toy motor for thrust.the things we need are.....
1. A computer fan( 12volts, 0.123 A)
2. 2 toy motors
3. 2 fan
4.Tape & scissor
6. RF Module(only if u r making wireless )
7. A remot
6. power supply or battery
8. A cardboard piece
9. A polythene
Step 1: MAKING BODY
First take your cardboard piece and make a hole at its center equal size of Computer fan.
Step 2: ATTACHING FAN TO CARDBOARD
I used a copper wire to attach motor to cardboard.Motor has small holes at the corner so i used it for attaching by making same holes on card board.
Step 3: Making Skirt
I used a polythene for skirt.polythene has handles so we have to cut them and we also have to cut bottom of polythene.now polythene is in rectangular shape as shown in figure.now seal the both open ends of of polythene.now it looks like a rectangular bag or your potato chips pack as shown in fig.Now make a hole on side of polythene slightly larger size than computer fan and make a rectangular hole on polythene on other side.
Step 4: ATTACHING SKIRT TO CARDBOARD
now attach your skirt to bottom side of cardboard by Tape.
Step 5: TESTING OF HOVERCRAFT
Now its time to testing ur hovercraft,is it working or not.so give motor to power.As you can see in image it is working.i have left a video for you
Step 6: ADDING PROPELLERS
I m using 2 fan and 2 toy motor for thrust.attach motor to cardboard by a glue.
Step 7: FINISHING
now we hv completed hovercraft,we only need to connect motors by your RF circuit.you can see completed hovercraft in fig.
