RC. Delta. Looks Like Space Craft

RC delta plane made out of styrofoam sheet (6mm)
it has KFM3 airfoil on it which is also known as heavy lifter airfoil that means you can fly it by carrying heavy payloads

now you all will think that why i had used this airfoil instead of regular airfoil ?

the reason is,

1)it is easy to build

2)very strong compare to the regular airfoils

3)it is heavy lifter

4)it has high stall resisting property in it

now let us start to build it you will require some

lipo battery 3s min 2200mah

I had use 6ch avionic transmitter and receiver , you can use any you have around we only require 4ch

prop size :- 10x45 gws

some other stuff

Styrofoam sheet

cutter

some tape

fiber glass tape

glue gun / some glue stick

glue (fevicole)

plyer

thin metal wire (for push road)

some wooden piece (for motor mount)

barbecue stick

main layer

first we have to cut out the main layer of our plane on Styrofoam sheet as shown in the above diagram this diagram contains all necessary dimension details.

just cut out second layer on Styrofoam sheet as dimensions given in the figure.

just cut out third layer on Styrofoam sheet as dimensions given in the figure.

now cut out rudder on Styrofoam sheet as dimensions given in the figure.

now last cut out of landing gear on Styrofoam sheet as dimensions given in the figure.

green one is middle landing gear you will need it one and blue landing gear you have to cut two of same dimensions.

after all cut outs the main layer will look like shown in fig.

now you have to apply an layer of tape where there is portion of ailerons or flaps because we will need to cut it from bottom so tape will provide some extra support.

first make some space by cutting both vertical lines on both the flaps so that it can move up and down easily as shown in first photo.

now you have to cut very gently on horizontal line this cut is not full cut but make sure that cut is enough to bend it backward without breaking it as in third photo.

not with 45 degree you have to make cut as in fifth photo now our flap is ready. now check proper that both flaps are moving up and down properly .

now you have to take some glue and stich first layer on the main layer and then stick the second layer on the first layer. wait till it properly dry.

now time to do some hard work take a one small piece of sand paper and start sanding from one side and give shape like airfoil so to complete our kfm3 airfoil. after sanding one side you have to do it same way from another side. Take your time and do it in proper way because airfoil is the main component of an plane

( I was in hurry so I do it very quickly but then also it fly's very good you can see it in an video )

now you have to stick three landing gear in there appropriate positions with the help of glue gun.

glue the rudder in position with the help of glue gun.

now the body part is complete now let us take an electronic part's.

first we have to solder an bullet connecters in the terminal of bldc motor.

now take an strong piece of wood as shown in photo now remove the mounting portion from the motor & make the markings on the wooden piece, make hole, put screw and your mount is ready.

This is the main part you have to glue the motor mount in its position as shown in photo with glue gun

but to glue the motor in such a way that the propeller tip is in line with the line of CG

you can buy an control horns and you can make control horns very easily from day to day life object like you can see in photo that I had made an control horn from wood , broken propellers ( I have so many broken propellers it is easy to make control horn from it ) , and the last one is from an vodapon sim card cover laying around.

not to make an control rod first cut an require length of metal wire and make loop from both side with help of plyer as shown in photo.

glue the servo in there position as shown in photo and then glue the control horn with the help of glue gun then put the control rod and done.

Take tape and apply it to the airfoil and now take fiberglass tape and stick it to the landing gear to make them strong .

now give additional support by putting barbeque stick in between two landing gears.

glue esc on the bottom side of the plane and put all servo and esc wires to the receiver.

now the most important thing is CG (center of gravity).

you have to manage it with placing the battery towards the nose in my case I find my cg perfect by placing the battery on position shown in photo.

If you want to make an different dimension plane you can make it but then you have to find the CG of your plane and you can find CG of your wing with the help of this website link is given below

your plane is now ready now just connect your battery and check all the control surface's are working properly and check the thrust by motor and now you are ready to fly it.

(if you are beginner then you can also give dihedral to this pale from the center it will make it fly more stable)

This was my first intractable if I had made some mistake then please forgive me .
