How to make a Super charge electric Air plane


Hi guys do u wish to send a paper plane more than 100 feet, then just follow this
The single-sheet paper airplanes you made when you were a kid (or perhaps last week in your cubicle) were, well, kid stuff compared to this beefed-up paper craft, which uses an electric motor from an old pager or toy powered by a big electrolytic capacitor. Known as a "Gold Cap" and made by Panasonic, the capacitor charges from a battery pack and then metes out a steady flow of power to keep your propeller whirring for about 10 seconds-just long enough to send the flyer airborne and carry it between 30 and 100 feet. (You can also add a gearing system to squeeze out even more flight time.) We've created plans for an eAT-6 "Texan" airplane and put them here and here to get you started. Just think twice before blindly launching this one soaring over the wall of your cube.


Build a Motorized Paper Airplane
Cost: $14.29
Time: 3
Hours
Easy | | | | |
Hard

Things Needed :
  • Paper eAT-6 plan (free; here and here)
  • Two 9x12-in. sheets smooth Bienfang Bristol Board (19 cents ea.; dickblick.com)
  • T-6 Texan Vacu Canopy ($2.96; squadron.com; #SQ9523)
  • Panasonic 2.5-volt 3.3F Gold Cap ($5.22; digikey.com; #P6966-ND)
  • Small electric motor (free; salvaged)
  • Plastic propeller (57 cents; towerhobbies.com; #LXHHV9)
  • AA four-battery holder (90 cents; digikey.com; #BH24AAW-ND)
  • Two header pins (27 cents; jameco.com; #103185-3)
  • Four AA batteries ($3.99)
  • Or you can find these above stuff  at your near by electrical hard ware store

STEP1 : PRINT THE PARTS

Download the eAT-6 plan PDF here and here and print each sheet on a separate piece of Bristol Board, or any thick paper that works in your printer.

STEP 2 : ASSEMBLE THE BODY

Carefully bend and glue the fuselage and wings into shape. Add the cowling and elevator, and glue the wings in place. Decorate it with decals or markers.

STEP 3 : MOTORIZE IT

Solder the Gold Cap to the motor, and solder two three-inch wires to the Gold Cap terminals on one end and header pins on the other. Slide the power system into the plane, and route the header pins out of the tail. (The capacitor should sit near the rear of the cockpit.) Glue the engine-nose disk to the front of the cowling, and add the cowling trim ring. Affix the plastic propeller to the electric motor's shaft.

STEP 4 : FUEL UP

Carefully bend each wing so it's angled up slightly. Install the AA batteries into a battery holder, and connect it to the header pins sticking out of the plane to juice the capacitor. Charge the plane until the motor is spinning at its maximum rpm, and disconnect it.

STEP 5 : FLY AWAY

Hold the plane and point it into the wind. Launch using a flinging motion with your arm, not your wrist. The plane will fly in a left-hand circle, the diameter of which depends on the amount of deflection that you bend into the rudder [see plans: 1, 2]. Bend the elevator slightly upward to make it climb.

Awesome MOD for Walk Along Glider

This topic is related to an Earlier post " How to make a Walkalong Glider ".

Hi guys i think u have seen my earlier post " How to make a Walkalong Glider ", today iam presenting you with an awesome mod to power ur glider

you need a extra of the following things (  It is Not tough if you can find these things) :

 

1. Old picooz rc helicopter's broken tail part 
                          or
     A small Pager motor or vibrator which u may  get for free of cost  in some    
     mobile repair shops

2. 3volts lithium "button battery''

3. Small propeller

                         or
     just follow this  "   http://www.instructables.com/id/mini-airplane/  "
     to make a cheap best propeller from old can



STEP 1:
 Just draw a red line on the glider as shown in the figure (just click on the image to zoom)

STEP 2:
Now make the power booster to the glider by connecting the battery, motor and propellor as shown in the figure , you can also modify little by adding a switch
STEP 3:
Now  just simply attach the power booster to the glider along the red line depending upon the balance point or CG(centre of gravity) of the glider after several test trials as shown in the figure

 Now just rock  the glider with ultimate fun but be careful  the glider may go far away from u leaving fun.

How to make a rubber band powered ornithopter

An ornithopter is a rubber band powered plane that flaps its wings. Leonardo da Vinci drew pictures of ornithopters in his famous sketchbooks, and several early-20th-century attempts at powered flight were ornithopter variants. Some ornithopters were propelled with oars; others used the arms and legs of the occupants for power. Some ornithopters were to be used with the aid of an inflated balloon. 

A BRIEF HISTORY OF ORNITHOPTERS
The ancient Greek myth of Daedalus and Icarus tells the tale of how Daedalus made wings of wax and feathers so that he and his son Icarus could escape from captivity. But Icarus flew too close to the sun and his wings melted, while Daedelus flew too low and crashed into the rocks. Both died in their attempts to fly. Another early story tells of King Bladud, who ruled in Britain in the 9th century BC Bladud supposedly constructed a pair of wings with which he proposed to fly. But, according to the monk Geoffrey of Monmouth in a history of the British kings, Bladud was dashed to pieces as he landed on top of the Temple of Apollo in the town of Trinovantum. Earlier, in 1010, a monk in Malmsesbury, England, attached artificial wings to his body and jumped from the top of his abbey to glide to only two broken legs upon landing. Other tower jumpers suffered death or injuries, while a few achieved some partial success with their glides. Later, Leonardo da Vinci, realized that human powered ones wouldn't be able to fly and drew sketches of some ornithopters of his own. Around 400 years later, the French inventor Gustave TrouvĂ© designed an ornithopter that was powered by an internal combustion engine.
