 rc hovercaft
this is a fun easy to build rc hovercraft that you can build from rederly advalable materials .this a step by step build of an amzing and fun to use rc hover craft.
 
tools/materials
hot glue gun
tape
balsa
polystyrene
corogated plastic 5mm
sail material
2mm wire harden steel
thin plastic
motors radio gear ect
soldering iron ,heat srink
 

Step 1: Making the Body

the body is made out of one inch thick polystyrene cut in to a rectangle 29x42cm. then a 15cm diameter hole is cut for the lift fan.

Step 2: The Skirt

the skirt is made out of thin sail material .to get the shape i cut 13x42cm strips and to get the corners right i used two halfs a pvc pipe that had been cut at a 45 degree angle then layed the strips over to fined out the shape of the corners witch turned out to be a s shape. the skirt is held on by black insulation tape because it is a bit more sturdy then selotape and more water proof.the skirt is attached around the out side of the body and a plastic plate at the bottom that is held on by foam spacers to let air through.

Step 3: Mounting the Lift Fan

the lift fan is a turnigy 2730 - 3000kv brushless out runner spining a 5x3 three bladed propand powerd by a single 850 2cell lipo. i mounted it using a strip  of  balsa hot glued to a 1.5 mm plywood plate that is bolted to the motor.then hot glued to the under side of the body.for the cowling i used a piece of thin plastic 3.5x50cm with a 2cm over lap.

Step 4: Testing Lift Fan

it hovers about 4cm above the ground at half throttle.with out forward motor and battery.

Step 5: Adding Forward Motor

the forward motor is a park 450 1050kv out runner spining a 9x5 prop and powerd by a 2250mah 3cell lipo . this is a motor that i had it dosent need to be this big but it just means that it will go fast. it is mount on to a piece of balsa that is glued to a right angle piece of foam. the tail section is made out of corrogated plastic that is in 3 pieces . the rudders are driven by a standerd size servo.

Step 6: Testing Time

it goes well on land as in croncrete and water. you can make a simpler skirt for it but it wont go on water because it will scope up water.
hi I'm starting a hovercraft group to share experience and designs to make the best hovercraft s possible I was wondering if you were interested
<p>yea it sounds like a good idea but this build was just a sper of the moment thing and i have moved onto building and flying multirotors.</p>
<p>well ,i like to make this as my 12th std project ,but can i use computer fan instead of the motor and propeler u used,cause i have it ready!!</p><p>what is the use of esc??</p>
<p>a computer fan would work but you will need to make it lighter than mine</p>
<p>its because its a brush less motor so you can't just plug it in to a battery to make it go it. the best way to explain it would be that they run on ac power so you need an bruss less esc to power it.</p>
video sucks
every thing besides the electronics are really cheapand the e;ectronics are still under a hundred dollers. <br>have fun building
This is really flawless. I just want to build this type of <a href="http://www.nitrotek.fr/bateaux-rc.html" rel="nofollow">hovecraft</a>, however. How much do you cost these materials? Are there any cheaper alternatives?
