hello everybody I'm How To DIY Rc today's episode you're going to
be learning how to build an armin RC wing for your Homemade Rc plane out of
cardboard so that anybody no matter where you live in the world young or old
rich or poor can copy my $5 trainer plane and this cardboard wings design comes from
Ed from experiment Airlines and Andrew Newton called
drew a good friend of my and I'll put links his video over here they built
the same wing with that out of foam and to build a wing of course you need a
sheet of cardboard and it used to be a box it doesn't really matter the wooden dowl
will be taking care of that we just need to make sure that the lines are
running horizontally to make it easy to fault wing the way we like it and of
course you need a wooden dowel I have a square one you can use a round one but
I like to use the square one because the small flesh that is contacted with the
cardboard to make sure you may always make 90 degrees lines or they are always
90 degrees nice and straight so everything's even you want to use this
little tool light got the name and of course 10 and a measurement tool and the
bigger the better it's always nice to have one that is
extremely long and then to make it really kids proof they also need to use
wood glue and scissors instead of sharp Stanley knife and some hot dog and of
course the most important thing you can't go out well in life it's take let
us not wait any long and let's get to it and with the core of the wing is 15
centimeters and then we need extra few millimeters to make this curve and of
course the upper curve needs extra few millimeters so that needs to be around
fifteen point eight to 16 centimeters long and then we need an extra four
centimeters for the aileron you can also build the same wing design with
reinforcement in front and in the rear with the wooden dowel to make sure it's
more durable but it also adds a lot of extra weight you take your sheet of
cardboard and the first line that you're making will be at 15 centimeters and
then you don't mark it out and make sure you make horizontal lines using this
tool over the whole length of the cardboard but the first line that you have set you
have divided the cardboard in two halves 16 centimeters and 15 centimeter
this will be the bottom side of the wing and there you mark a second line at 30%
there is at five centimeters so at five centimeters from the middle line you put
a second line and this is where Andrew Newton likes to put this wooden dowel
I prefer to put it a little bit in between 30% and 25% so I set a line of
30% and I just put it in front over 30% know that you have marked cardboard and you
have set the lines we're going to pre fold the first line and I'm using a
piece of wood to sit on the line to make the first fault you just need to
make sure that the wood stays in this place if you don't get that right as you
already can see we made the fault at the wrong place we want this fault to be in
front of the line not at the rear tip number one use wood clamps to clamp it
down to the table so you make sure the wood don't move
as always is to the second booth or down tree don't get that kink and spread the
load evenly around the cardboard first and at 90 degrees and then slowly
try to bend it more more and more eventually you get it completely flat
and I press really hard down on that first leading edge now you have to repeat
this process a couple of times moving every time five millimeters to
make the first curve of the wing now we have finished pre-bending the front
leading edge time to glue down the wooden dowel with some wood glue
of course you cannot always keep it here forever so we're gonna use wood-clamps again
so it stays in its place or you can add some stones or heavy weights to put pressure on top of it
welcome back to a new day overnight we have dried out the wood glue now it's
time to add wood glue on top of the wooden spar and then fold down the wing
make sure the end points touch each other if they don't pull them towards each other
to make sure it's a flat surface and the wooden spar will be sitting right at
the correct place and then use some scotch tape to hold the bottom and top
plate together and then of course make sure you have the nice airfoil and then
put pressure on it by using some heavy weights some
pressure weights and then leave it again for a couple of hours to dry out now the
tools finally dried up and the wooden spar is completely glued in now it only
time to add glue to the rear edge and then we are putting pressure on using a
big plank and a few wooden clamps I'm gonna wait a couple of hours again a
little bit to put the glue together it's almost finished and now it's time to add
some tape to make it stiffer stronger and semi waterproof
and a first we're going to do it horizontally
the next step after we have tape the wing simply now we have to with a
vertical and let's go all along two-way tape to tape to make it really strong
and step into this row for row go all the way or to this just a couple of times
spread out over the wing and it'll while make your wing a lot stiffer and protect your
wooden spar from breaking the last step is cutting out the elevator that is the same
length 50 centimeters and it is 4 centimeters wide and then of course also
one layer of tape or the next time to add the elevated to wing and everybody
got there own way I'm using four small pieces first to line up the elevator
with the wing then we're going to add three layers of horizontal tape the
first one right on top of the edge and then number two above and the number
three below it and was the last step in how to make an Rc wing with cardboard
now you can finish your cardboard airplane of plane on a stick like my $5 trainer to be
linked up over here but in the next episode we're going to make this wing
into a Polyhedral wing that makes best trainers plane in the world now
super easy to fly and the best for a beginner to learn to fly so if you're
