corogated plastic 5mm
2mm wire harden steel
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.
