hello there we are going to make a string guided flying bird which can fly inside house like this for this you need bamboo sticks the five Bain sticks lengths are shown in the screen you also need a five centimeter long refill five making you like the center and glue the longest steek at the center the glue then take 0.5 mm he copper wire bend it like an arrow you cut the length about one centimeter long and then glue the 12 centimeter long bamboo stick and tie with worse like this now from the front of this mark at 2 and 1/2 centimeter and wind a copper wire there sticking it out 1 centimeter long 90 degree to the slot and glue it again thus you have to make to these two sticks are 4 wings now I am going to glue two sticks the smallest takes 4 tails and tie it with West does a 3 main part ready now cut a 3 centimeter long and a 4 and 1/2 centimeter long stick glue the 3 centimeter long stick about 1 centimeter away from the fraud and tie it very tightly with strings you can put extra glue now glue the 4 and 1/2 centimeters thick also to give it a support and dive it with strings to have a strong structure now you need 1 centimeter long gel pen refill put that 90 degree and tie with the strings this structure needs to be very strong now we need a 3 volt DC motor at the center of the DC motor glue a pipe and then tie with worse this motor I am going to feed in such a way that it axis exactly passed to the gel pen refill take the hell of a well glue it and tight main body now take a safety pin open it up take the wire bend it negatively taken on 1 cent meter and bending and editing and this will be the shaft this shaft you need to connect with a mortar using a coupler I have used a small pipe as a coupler to connect the SAP be sure it is tightly connected now take the two wings pass it through two small world at the end of this five centimeter long rifle pass and bend the word on the other side now make a crankshaft from a strip of plastic make a deal at the top pass a pin through it then put that structure through the two slot and on the other side cut the lane extra length of the pea and put a small piece of pipe and glue it so that it doesn't come out now measure the longest length that sub can go mark there make a drill cut the extra length of the crankshaft now pass it through the main iron shaft stick some bouche which is nothing but the pipes I have used the same ripple pipes and glue it be sure it is freely moving now power the DC motor using a 2.7 board lipo battery connect it with the motor using a switch in series like this switch it on you can see that wings frame is flattening now to make the wings you need plastic cut it from a plastic bag first stick the tail center of the tail cut the extra plastic out like this and then stick both the side using cello tape that the birds tail is ready now you can paint feather like structure there using a marker now for the long way glue the body or the spine cut the extra plastic how and then use sellotape to glue the frame with the plastic wing you can draw figures with the marker like this now take a paper and wrap it around the motor on the battery so that nobody can see on the top stick a string using a sailor tape and then C so that is balancing properly or not if balancing properly then take a length of one meter string on the other end of the string connect a plastic and then put some double tape using the double tape hang it from the ceiling now if you switch it on you can see the both the wings are flapping if you push it it will take is far soon and will start rotating round and round and it fly around the house say isn't it cool hope you have like make your own bye
