- [RCSparks] So many years before I built the Top Gear Toybota
or the Nissank,
the amphibious truck that you see there
with the boat motor on the back,
I'd built the to kill a Toyota truck.
Now viewers, long time viewers of this show,
will remember that truck, rest its soul,
'cause I finally did kill it.
But who would have known that
when I was in Hong Kong in 2016,
I was gonna meet a designer that was going to fabricate
a one tenth scale ripsaw.
This is another vehicle that was seen on Top Gear,
in fact, Hammond got to give this a rep through the desert,
and I've seen smaller toy-like versions of this online,
but this, my friends, is a complete kit.
Now yes, I'm even jealous of myself,
because this was sent to me by the designer
that I had met at that time from Pig Studio,
I'm actually going to leave a link down
in the video description box on YouTube here below,
where you guys can go and check out
pictures, and videos, and the website, and his Facebook,
the whole deal,
because this whole thing is mostly metal.
Look at this, I'm sorry about the fingerprints guys,
it just, it is impossible to get them off.
Look at this though.
Side doors that fly up on either side.
My one tenth scale driver that I've had for years
holding onto the steering wheel that's special made,
I'm gonna spin this around so you can see,
this normally comes as a kit.
Now you guys know I've been building an excavator,
and my friend was so excited
he wanted to send this out to me here already
as an almost ready to run,
because he knew the snow was flying,
even though this is an all-terrain vehicle
not just for the snow,
I don't really have any mud around here
at the moment though, but look at this guys.
Look, I'm excited to see this,
I have seen the videos of him making this
and how fast this can be.
Let's have an open of the back here.
Here's the tray,
and then underneath the tray,
I'm still learning about this myself,
I'm gonna take out the ESCs that are linked together
and the top light, the LED light,
two ESCs for these two brushed motors.
Look at this.
Belt-driven.
I love that direct drive.
You can bypass the transmission get right to the speed.
Now the interesting thing about this is today
I'm gonna have to put in the receiver,
gonna have to figure out the battery and the ESCs,
and then I'll be able to figure out
how to mix the controllers on pistol grip radio,
so I control how this turns.
If anybody is familiar with how a tank moves and turns,
normally one track will move on one side,
while either the other one stops
or moves in the opposite direction,
and then there of course that way
it can turn left and right,
so that's how I'm gonna do that with mixing,
you guys are always seeing the coolest
and most innovative RCs in the world on "RC Adventures",
I've gotta tell you I feel lucky to be
on the show with you guys,
I would appreciate it if you guys
smash the like button right now,
show some support for this amazing kit right here,
I wanna get right to work so let's do it.
Okay so first thing I gotta do is
bind up a four channel, doesn't need to be a four channel,
that's what I have for my Noble,
this is a FlySky NB4,
just gotta bind that up and done
Aha!
So I'm gonna have to link
these ESCs together and I'll show you what I mean by that.
Only one ESC should be powering a receiver, right?
That's how a receiver gets its power
unless you're using a direct BEC.
Which we've covered before
and if you wanna know what a BEC is
all you have to do is search what is BEC.
I'm gonna wanna remove the red wire
because the red wire is the one
that actually supplies power to the receiver.
So get that, we only need one ESC that has the red wire
to power the receiver.
So I'm gonna remove this one.
Kay, so there's this little tiny tooth
right in the middle here,
that's what actually holds the pin in place.
So I've pulled it up,
and in that way I can just slide this wire out,
a lot of people clip the wire,
you don't really need to if you just bend it back,
and then put a little piece of electrical tape there,
in case you ever wanna use this ESC
in the future for something else
that way you can use it again.
Push that little tab back, and there problem solved.
Some people will say take out the negative wire as well
you can do that.
If you are worried about the negative feedback loop
because of that black wire, just make sure
it's not touching the post of the red wire,
because that's the whole point to this harness.
Next what I'm gonna wanna do is identify
which one of these channels is gonna be throttle,
and which one is going to be steering.
In this shot you can see I've laid out
both ESCs where my throttle is gonna be
the one on the bottom, so it's got all the wires
including the red one,
and that the steering which can be the one on top
which just needs the signal wire.
Well I guess I can't call it a direct drive
now that I notice that there is a transmission
on the front of this motor.
I just don't know what the gear reduction is
in there if any.
Now as my batteries charge in the background
here is an accessory LED light,
comes with this you know this very thin metal
like it looks exceptionally heavy for a tank,
but it's very thin metal so it doesn't weigh like
too much, like it's definitely manageable
for somebody like myself.
I'm gonna go ahead and install the light
right behind the bracket here,
So here is the ESC and as you can see it's got jumpers.
Now I've removed the top jumper which has given me
immediate forward and reverse
there's no brake involved, okay?
And I also have it on lithium polymer setting for battery
not the nickel metal hydride.
So I'm removing this back plate,
here's the light, the LED light up top
I haven't installed it on this side
just this side,
this is where the ESC and the receiver are gonna sit.
Well two ESCs,
and I'm gonna run the wires down in the two holes
that are on either side.
That way I don't have anything down in the tray
where I might get water, mud or whatever,
everything will be protected somewhat up here.
Now you can see I've got the motor wires running up,
but instead of having to worry about them
getting caught in the belt,
and yes I do have some shrink wrap here not done yet,
I'm gonna take a twist tie, or not twist tie, a zip tie
and zap strap that together
so there's no way that these wires can get caught up
in the drive.
And that's exactly what I mean.
Such a great design.
I love this machine, the more I work on it
the more I'm falling in love with the rip saw.
Check it out, for those that are like
confused about the electronics,
this is pretty straight-forward.
An electronic speed control on either side
to control either track,
both of them are basically gonna stay in the on position
and I'll use the battery connectors
as the actual on/off switch.
Now I know
where the length is gonna be for my motor wire
so I can shorten those up and get that installed
and really install the tray for the batteries.
Now here is the battery tray,
we'll get these plugs out of the way,
slide this in, it gets screwed in here,
glad I gave myself a little extra length on the cables,
oh, I bet the cables have to go
through these holes right here.
Well that's fine, that's why I didn't connect anything
shorten them up.
A few screws on both sides,
kay, so for the final piece for me
I had to put in two corner inserts
right at the back which allow this top mounting part.
Now I am using 5000 milliamp 3S Lipo for each ESC.
Yes these ESCs can handle it.
These are hard cases which means
they're gonna be a little bit high for the case,
that's okay though I don't mind.
What I'm gonna do is I'm gonna velcro them
in on the side on either side.
That will go on the side of the battery
right along the inside here,
so now both of these are going to be stable
not moving around
I could probably add just a piece of foam
or something in here if I wanted.
Kay time to plug it in,
hopefully it doesn't take off on me.
Let's turn on the radio first.
And because I have experience with doing this,
I'm going to elevate this off of it's tracks.
Just in case.
All right, let's get these two plugged in,
one ESC chimes in,
yeah and the other.
Sweet, now I just have to do a few mixes on my radio,
put the cover back on,
and I should be able to be good to go.
Kay so I've got it turned around okay?
And now you've gotta see there's two ESCs
plugged into channel one and two.
There are three mixes that I'm doing.
Here's how I'm turning,
then I turn the other way,
now what I'm having to do
is to make my steering the master channel
and the throttle the slave.
But it's not two mixes, it's three.
Now throttle,
both go forward,
both go backward.
And of course it's incremental.
(engine roaring)
Woo hoo!
(engine roaring)
You guys can see look how big it is, hey?
So there it is.
And then left and right.
So if I'm going forward,
I can still push left or right.
It just slows one down,
And reverses it.
Shall we take it outside and see how it does.
This is probably driving half you crazy.
There you go.
You're welcome. (laughing)
Hello! (laughing)
The first roll, woo hoo hoo!
Let's see how it turns!
Yeah!
On a dime it's like zero turn
takes no room to move around at all.
Let's go outside.
(engine roaring)
Only minus 15 today Celsius.
(engine roaring)
Unbelievable!
(engine roaring)
There's me driving it!
(engine roaring)
For my first round out and about,
a little bit on the cold side to be honest with you guys.
(engine roaring)
Holy cow!
(engine roaring)
I wanna open this up.
(engine roaring)
Look at this suspension moving.
So cool!
(engine roaring)
It's hard to film and drive with one hand
when you're driving this track machine
but, no excuses, you can see I left my receiver antennae
out a little bit there just to give her a try.
Look at the clearance on this machine!
(engine roaring)
Well, there goes the GoPro!
(laughing)
This is gonna take some finesse to learn how to drive.
It's so cold the GoPro, didn't even wanna stick to it.
Look at this so why would take finesse to drive
is really learn how to throttle control
as well as turn at the same time
even though they're individually controlled,
now normally I'd use something called the Sabertooth
which is like a robot track controller,
(engine roaring)
but I'll tell you
learning how to mix two ESCs to work together,
that is another feather in my RC expert cap
like wow, whoa way too close.
What an amazing looking machine.
Kay, so there are some shots
that I just cannot get without the help of my lovely wife,
Jem in the background, how is it going baby?
(laughing)
Let's take this thing out to the field
and see if it can really do. (engine roaring)
Let's go mini me!
(engine roaring) Woo hoo!
You ready for this?
- [Jem] I'm ready.
- Cyclone action?
(engine roaring)
(Aaron screaming)
It blew a track right off!
(laughing)
That will be worth it in slow mo. (Jem laughs)
Kay so, since this already came to me put together,
let's look at the inside track,
'cause we're all probably wondering over time
if it's gonna stretch out,
but that's pretty gnarly,
like that's got a lot of bite on it.
And yeah, I was doing cyclones on the rocks and dirt,
what did I expect at high speed.
So this is interesting as I go to put this on, look at this,
this wheel actually has a retraction system
which allows me to put the tread on easier.
So it's a tensioning system
which answers if the track starts to stretch out at all,
can you add extra tension?
Yup.
(upbeat music)
And three, two, one, let's do it.
(engine roaring)
(laughing)
Look at it ripping!
Woo hoo!
(upbeat music)
Look at that, that's full speed on 3S right there,
with those brush motors, look at it beautiful though.
Woo!
(upbeat music)
Not often any tracks that
I thought it might wanna pop tracks,
but on the grass it's going perfect.
Let's go the other way.
(upbeat music)
Oh yeah, it's calling for brush
but it makes me wonder if I put too much power in there
will it actually throw that track?
Like this is a comfortable scale speed.
It's a! Whoa!
Almost ready to the, just to it. (laughs)
(upbeat music)
Yeah, baby come on!
Right through the snow!
Woo hoo!
(upbeat music)
What a little monster!
(upbeat music)
(laughs)
Woo hoo!
(engine roaring)
Aw I popped my track again!
Aha!
Right here.
Well, it's pretty cold out
everything is getting pretty tensed up
but probably what it needs is some adjustment for sure right
'cause I haven't adjusted this at all,
I just kind of got it out of the box and let it rip.
(engine roaring)
There it goes!
Pig Studios right there!
The Rip Saw!
Another Top Gear rig
glad to be able to showcase it for you guys here.
Look how snowy it is now!
I'm gonna go thaw it out.
Speaking of which I can barely feel my fingers!
Until next time guys.
Go inside and have some fun with RC!
You know I always do.
Bye for now.
Woo hoo!
Look at that little ripper go.
(engine roaring)
Get all that snow off smooth circus wise.
(laughing)
You know they're not gonna get out of this
without doing an epic cyclone.
(engine roaring)
No thrown track there.
(engine roaring)
Yeah. (engine roaring)
(laughing)
What a machine!
(engine roaring)
