hello everybody and thank you all for watching again how to make an
indestructible $5 trainer plane episode number four where we going to
build in the body and motor mount slash firewall step one are the supplies that's
going to be needing is a 80 centimeter long 2x2 or actually 18 mil 18 mil
a 2x2 this much more easy that is super strong and stiff and doesn't Bend and
flex you also need the 35 centimeter long 5 centimeter wide wooden plank
wooden board that is multiplex or threeplex and it's also very stiff and
strong and gonna cut it and three or four different lengths or three
different lengths and four pieces two times five by five centimeters there's
gonna be the motor mount and the support then a piece of 15 centimeters there's
gonna be the support of the main wing and then a piece of ten centimeter is going
to be supporting the tial section you also need five screws that are 2 and 1/2
centimeter long and some wood glue some wood clamps and a screwdriver can always
be handy and of course and drill machine and that's all you need to make an
indestructible body for your five dollar trainer plane the best plane to learn
to fly because it gives you the most seat time and step two you need to make
the body but that's already done that is right simple 80 centimeters stick so
let's go to step 3 and make the motor mount the first step of your firewall
is finding the center so you mark you cross it when you found the center we go
to your motor that comes with a nice the motor mount and a prop adapter and
few screws fully packed with accessories to make it one step that
fits everything to make it super easy for you second step is finding the
center with a motor mount and you can't place it in two ways some people like to
place it this way but if you are having to put a motor on an angle then it makes
a lot more sense to put motor mount this way second step if you found the center
is keeping it there making sure everything is nice and level some people
like to mark it and then drill the holes and then you still can be a little bit
off to my way of doing with this putting a screw in there
none of the motor mount is hold on to by two screws it's not going to
move now you can easily drill open I have placed two screws in those and we
are gonna remove the other two screws now we can drill those in the next
step we are going to prep the main wing supporting this actually just finding
the center and then drill two holes from the two centimeters from the edge is
pretty easy pretty simple straightforward let's get to the tail
support and it's ten centimeters long and again you find the center and then
off the center around two centimeters you drill a hole so we can attach that
to the body in the next sstep we are going to add all the pieces to the body and
the most easiest is the tail section let's start off with that first and just
need to make sure that everything is centered up and lined up so I add it on
line all along the body marking the center of course and then it's just easy
way of lining things up let me use some clamps to keep it in place and drill the
hole at this time I like to add those screws and make sure that the tip just
sticks out at the bottom and then now we add wood glue towards the tail and then
screw the tail section in this place also make sure that the screws goes into
the wood so that it's completely flat there's one little piece of information
I forgot to tell you before adding the tail section is that you have to look for the
grains of the wood and make sure you drill from the top compressing all the
layers of wood together because if I were drilling sideways to this wooden
stick in between the grains I would just crack open and split open and you would
loosen all the strength of the wooden stick motor mount design is going to be
very simple with the supports going to be sitting on top with a motor mount in
front so you need to make sure that everything is nice and level and that
your stick is completely level out and now you need to mark it so I can find the
center so we can drill a hole with a screw to attach to the body then I
mark how big the stick is this 2 by 2 or 18 mil and minus 9 millimeters
so I find this the center we have to drill one more time to put a screw
inside the body you're also going to tap out the hole a little bit so we don't
get problems with the motor mount and the screw is sitting completely flush
the only thing that you have to do is find the center of your wooden stick and
then drill one more hole we already putting the screw with the point sticking out the
rear so now we can put some glue on the wooden stick and glue those two together
sure you screw it down really nice and tight with all the wood glue spreading out
the rear and we're gonna add a little bit more wood glue and a little bit more
on top of the stick and I always like to put it there and move it around a little
bit spreadding out the wood glue keeping it in
place and you should have things nice and level and lined out in the center
and in this case we're just gonna use some would clamp and and some more wood
glue just to fill up the gaps and that's the last thing you'll be expecting us to
put the main wing support already on top of the body and mount it nice and firm
but that step has to wait because it's gonna be the last step after we added the tail
on the motor and perhaps landing gear and that is all coming up in the next
episode where we also have to find the CG and then we also gonna add the main wing at
the correct position after adding all the electronics and the tail section and
perhaps landing gear so please I hope you subscribe for that if you're new
to this channel and click the notification bell so you will be
notified when the video will be released and if you also need your support and I
really hope you give it a like I can use it a lot and will be much appreciated
and I want to say goodbye and I hope to see you next time
