Step 6: Finished!

Picture of Finished!
To start, place the hovercraft on a hard, smooth surface. Put one of the wires from the battery snap through one of the holes in one of the contacts on the back of the motor and bend it so it doesn't come loose. Then, put the other wire through the other hole, so that it just barely stays there. That way, it's easier to remove when you chase it down. If the propeller blows the air forwards, reverse the wires. Also, this is a 1.5 volt motor, so hooking it up to a nine-volt is not good for it. Don't let it run for long periods of time or it will burn out the motor. It works by creating a high pressure zone inside the meat tray. The escaping air travels under the rim of the meat tray, causing the tray to lift off the ground very slightly. The top part of the propeller provides lateral thrust, causing the whole thing to move forward.

Hey. I'm building a hovercraft in school. We're using two motors? What do you suggest that I do?
For the fan for the downward thrust you should use the one that are used in computer cpu's for cooling down parts.........you can easily screw and tape it to the tray after making a hole for it......and for the vertical thruster you can easily use dc motor.......if you want to make a rc hovercraft you can make flaps like those used for setting the direction of air in car ac's and connect them to a moter.......
get to meat trays put the small tray over the other use match sticks between the trays with a space of about 1/2 a centimetre make a hole on the bigger tray then u finished the hvercraft produces more thrust

would a usb hard drive motor work for this?

Wasn't this by klutz? it seems like you just took it out of their battery science book

hey, my fans starts to spin really slow after 10 sec... any idea to why?
Your propeller could be too big or too heavy.
I think that your fan spin because you (removed by community request) put the motor a little angled, thus producing angular thrust. You cold either try moving the motor more towards the middle of the craft, or un-angling the motor.
Wouldn't it be easier to just add a small switch instead of moving the wires every time?
where do you think i can pick up a propeller? I'm really interested in building this project!

Just finished our 15 minute hovercraft 2hours later. It was not as easy as I thought it would be. We used tape instead of glue to make it lighter and it worked great. this is for a 7th grade science project for extra credit. We also used a hand held fan for the blade to propel the craft. cost about $8.00 make

Hey, mine keeps going in large circles. but anyway, great instructable, keep it going!! For all other people, using a paper plate is OK for teh base
Does the motor voltage affect how good it hovers?
