Good morning Youtube
as always you see me start the video in a car, but I am NOT on the way to a event
but I just arrived at my workplace, parked in front of the office
Today my Fireball arrives :)
Today comes the Fireball! I am so excited!
And I have to work.. :/ It will arrive here at work
I think around lunch time
and then I will still have to work 3 hours more,
desperately wanting to build it
I will try to stay calm
and I will keep you updated
I will definitely film the unboxing today evening
and collect some first impressions
but I am also invited to watch the new Game of Thrones season at a friends place
so I will not have that much time to start building
but I will do as much as I CAN
nonetheless because I WANT
to do as much as I can
we will see what happens, I keep you updated!
Well....
look what I got here... :)))))
It is hereeeee
I just had lunch...
now this box arrived..
and I still have to work till 4pm until I can open it :(
and that I CAN work until then
I will put this box
in my car where it will stay till I finish work
Heeey
I finished work, I am on my way back home
now I will assemble my Goblin, I just cant wait
I already prepared everything at home yesterday
Camera, Tripod, lights, everything is ready
so let´s drive home and start building
Tadaaa here I am at home
and finally I can unbox my Fireball
I am so excited
I nearly wasn´t able to work ^^
I was all the time thinking about this box, haha
So THIS is the box
its not really big but there is a whole heli inside
and I ordered the Super Combo from SAB
so that means inside is the Heli
4 servos
and a Hobbywing ESC with 60A
whats missing is a LiPo battery
as you know I fly Optipower
I orderd one from there
the FPV Drone Quad Racing pack
its super tiny
1000mah 6s 50c
which is within the recommended specs of SAB
and as you also know I am flying Graupner
and for that reason I will be using
the Graupner FBL Gr-18
this is a combined FBL and receiver
thats super space and weight saving,
especially handy for little helis like this one
So these are the devices I will use
and now lets open the box!
As you see we have this nice little box
and here we have
the instruction manual
as always printed in colour and in english
heres also a little extra
booklet
here is the Goblin registration card
as you know: Register your heli
so you will get the latest updates from SAB
here is the
sticker set which we have to put on the heli
more stickers
aaaaw here is the tiny little heli
as you can see
it is really cute and tiny
and here we have
the landing skid
which will look like this
here we have the cute little
main blades
the tail pushrod linkage
a cute little blade caddy
in here are the rc devices
in here are all the little parts
for building the heli
here is a small manual
for the ESC
here we have
the ESC
servos
more servos
the cool new motor
here it is
very chic
a bit heavy
but i think that will be okay, I trust the guys from SAB
and now to the other box
box nr 2
as always
all the little
parts for the build
as usually from SAB they are labeled
with bag numbers
so if you stick to the manual
it is nearly impossible to do something wrong
So ... lets start building!
Hello as you can see its bright outside, I wear new clothes: Its the NEXT day!
As you saw I already mounted the motor, the tail servo and the ESC
also without the camera
I soldered the batteries and the ESC connector
what I will do next is
to connect my FBL with my TX
create a new model in the TX
I will then center the servos
as you saw
I already mounted them into the holder
I have to install them here on top so I can then mount the main head
and just in case that it maybe hard to
access the servos later (what I dont know but I am just precautious)
I will center them now
then finally mount the servo horns
then I will install the main head
and I think then
the biggest part should be done
so that means I then can start
to install and program the FBL
and I can program the ESC
and if everything goes fine we maybe
can do the maiden flight tomorrow after work
so have fun with the further building
So this is what the final thing looks like
I also put the stickers on
it was a bit of a work
but i think now the tiny little
joghurt can looks quite pretty
here is the Lipo
you see its quite at the front
i think due to my wish
to choose a lighter battery
to not make the heli too heavy
now i dont get the center of gravity correct
this is the furthest i can go forward
unfortunately it is still tail-heavy
how this will affect the flight performance
i would recommend you
to choose a bigger lipo with more capacity
or you put rc devices to the front
for me it didnt work :(
what you can see here
is this guidance for the servo wires
under the main shaft dampener
this solution is easy, clever and super easy
here on the main head
we have a small plastic dfc linkage
not typical for sab but for this
size completely okay
here you see the tail belt
is running directly ON the motor
the ESC snaps easily into the
main frame
so you just open the frame with two screws
you put the ESC inside
close two screws
here is an additional cable tie
thats it
what I also like
there is a guidance on the bottom
for the esc cables
its also recommended in the manual to put the cables there
the motor connectors
are here in the front
easily accesible
when i realized that the motor was running inverted
so i didnt have to solder something
just take the lipo away and change the plug
also we have here
two simple and easy belt guidance
which push onto the tail belt
it looks a bit adventurous but works pretty fine
dont know if you can see that
the tail belt is passing
just around the tail servo
it works
at the beginning it didnt know what this is
until i mounted it
then i realized its for the servo cables
that is so super genius
you have it on both sides
here are no cables but i mounted it anyway
This is not so beautiful, I know
but it should do the job for the test flight
to see if everything works
as always with SAB you have these
three lines on the main head
to see if you have the 0° pitch
and where max and min pitch is
the tail is typical SAB
so you have these
four screws to loosen or tighten the tail belt
the tail runs smooth
my Graupner FBL has its place here
the space is just like built for it :)
it ends right before this tailboom click part
in order not to have
the antennas hanging down
i taped them on the boom
i know its not pretty but for test purposes its okay
so thas my complete package
i think
it looks pretty awesome
as always very pretty this little machine
here are my Optipower lipos
which are perfect from the size
in my opinion, like made for this heli
also the cable length
is perfect
nothing to complain
only thing, as mentioned, it would have been better
to take one capacity size bigger so they are a bit heavier
but we will see how this all works at the end
Here is the included anti-static kit
I didnt install it because Graupner
isnt very sensible for that
I hope I wont need it
for that reason its a small heli
if its really struck by a ray and makes it crash
the crash costs should be in a cheap range
so i will risk it
i will now shortly show you
what i programmed
You see here I did a model
with name fireball
I had to invert the
three swash servos
but that maybe different with everyone of you
what else did i program?
My Autorotation
Three flight phases
I noticed that the HW ESC doesnt spool up
if you have less than 50% throttle open
So my first idle is 50% throttle for starting
Idle 2 is around 60% and Idle 3 75%
I will have to test these on the field
Pitch curve is completely standard
The max and min angles are set up in the FBL
I programed an Autorotation switch
and all the rest is setup in the FBL
Now I show you the FBL settings
All the basic stuff like "Heli" "Language"
You see I activated the Experts menu but I didnt use it till now
All the settings are BASIC DEFAULT settings from the beginner menu
I just unlocked the expert mode, in case that I need it later
so swash and tail gain is all DEFAULT
I just did here: Swashplate 120°,
the frequency of the swash servos
my swash direction
you have seen this in my G500S building video
here you change the value until the servos
move together in the right direction
for example when I give pitch, they all should move up or down
if your swashplate goes reverse
then just invert the servos in the Tx
(like I did)
but they should move in the right manner
this is swash direction
the servo center option you use
to put your servo horns right into the center position
so the swash is levelled at 0° pitch
With swash cyclic you change it
until you reach 7° cyclic pitch
i normally do 8° because I like it better
swash travel A and B,
here you just give full max and min pitch
and adjust the value until it fits your needs
so for me its + / - 12°pitch
Swash limit is really high for me
I dont get the servos to mecanical bind
thats quite unusual but I leave it with 100
I am surprised because I never had a value that high
swash rotation is just for scale, not usable for us
tail servo, here VERY IMPORTANT
to set the speed to 760
the default value is higher and
the tail servo will not work until you set the right speed
so at first it was broken, but it just was my fault ^^
tail servo frequency to 333 hz
the tail servo middle we dont need
here is the tail limiter.
adjust the value so
your tail pitch slider can go aaaall the way
on your tail shaft,
so you get the maximum tail performance
Expo YES
Logging is default
and now only the gyro setting is left
i showed it to you in detail in the G500S video
so you just enter this menu and
check "New" and say YES
activate Aileron and steer Aileron to the right
then you take the heli and incline it to aileron right
then activate elevator and steer elevator to the front
then you incline the heli to the front by hand. for tail you steer tail right
and then rotate the heli by hand to the right
then afterwards you take the heli and check if the gyros work properly
and check if the gyros work properly
i dont give any guarantee on
the values i use in my setup
please always check it for yourself
and dont rely on just coping my values
if your gyros work right then nothing bad can happen
so this is my basic setup
so now there is only left to say
the basic setup is done for the maiden flight
and i think
we will meet tomorrow on the flying field
for the maiden flight
lipos are charged but its too late now
8:30PM is too late... :(
But tomorrow after work we will do the maiden flight
promised! Bye Bye!
