- Okay guys, remember this a 12 pound truck.
I wanna see how the paddle tires do
with the added drag of the outboard motor.
And then we'll add the power of the outboard
to see how it does overall.
So viewer requested, I actually was asked
if paddle tires would actually do this truck justice.
This is the Toybota. I did cross the scale channel
all the way across the pond with the outboard motor.
But in the very first episode, the maiden voyage,
we saw the truck power itself back
with just these stock tires.
Now these are 1.9 sized with aluminum bead-locks.
You guys can see here that I ordered 1.9 sized sand tires,
gonna mount them up on aluminum bead-locks as well.
I wanna see if these paddle tires actually make it across.
I'm gonna take the outboard motor
off on the back to reduce the weight.
And I wanna see how well this actually works.
Always wanna sure that the tires direction is always proper
to when you're putting the actual wheel on the inside.
Remember with paddle tires one side does not fit all.
You wanna make sure that the direction is the right way.
Bead-locks go on the inside, starts with a ring.
This is the inner ring that will
actually hold the bead of the tire.
Just wanna make sure that the bead lip is on proper.
Flip it over making sure the bead is lined up well,
plus the foams are also seated.
Gonna put that bead-lock ring just on the inside as well.
You can see it just seating perfectly.
You never need to cinch down the first two all the way.
You just kinda want to get them started
so you can start the other screws as well.
You'll notice that I started on one side
and I've kinda done a star pattern so opposite sides.
I started here, immediately to the other side,
then a 1/4 way, immediately to the other side
and then I'll be going up here.
The reason I'm doing a star pattern like that
is so I can get equal torque on all of the screws
and I have an equal cinch all the way around that bead rim.
Just going around the outside cause you'll see
the actual first screw I have here, even though
I'm doing the 2nd tire here, kind of magic of TV.
You'll see it's actually loose and the reason why is
'cause each one of these screws
that goes down after the first one,
kinda cinches that lip down that much more.
So you wanna go in once every few runs,
make sure your bead-locks are done up properly.
I wanna make sure this is nice
and tight for the water crossing.
I'm gonna be running on 3s LiPo which is 11.1 volts.
Removing that back outboard motor will remove quite a bit
of weight so I'm actually wondering how this
is actually gonna float in the water.
I imagine fairly flat and I wonder what kind
of speed we're gonna get out of it.
Alright mini-me you're all strapped in good luck buddy.
Your steering wheel is still going to work
which will control the front tires all on their own.
Your outboard motor is now gone make sure
to have your head up pointed straight forward.
The water cannon which is expelling water
from the back here is on-demand.
It goes through a pump, slurps all the water
from the back tray into this pump here
and shoots it out of the water cannon 14 feet.
Now in 1/10 scale if I was to multiply that,
that would be a 140 scale feet so (laughs)
plenty of power to get the water outta here.
My friends, we've taken off all the weight.
Right now she must weigh about,
I'm gonna have to say about seven and half pounds.
Everything's charged up, let's go the pond.
I have no idea if this is gonna be even worth it,
but if I don't try, I won't know.
(engine starts)
(engine whirring)
Alright 3s LiPo let's go. (electric motor revs)
It's in low gear right now, with a 40 turn motor
it will be a very slow crossing but I think we should try
and test it out in the canal
which is actually a moving body of water.
Everything should be good to go,
and it should be able to drive right into the water.
Let's see how this goes. (electric motor revs)
There we are, floating.
Whoa, a little bit of a slip.
Let's see here I'm gonna have to have some real traction
if you can say that in the water.
Look at this, the paddle tires are working.
But I definitely have a little bit of a problem.
The problem being is that I'm also again starting
to plow into the water.
Very interesting when I don't have the outboard motor
on the back to help it stay stable, that it plows like that.
(muted engine whirring)
(laughs)
You can see with the weight of the outboard motor though,
it may actually help with these paddle tires.
Because it does have the flotation, it does have the speed.
Check it out, look at this.
But it's plowing more than anything.
See that hood, trying to go under the water.
Not too bad, this is basically maximum speed.
There's crawler speed, and then high speed if you will.
So paddle tires may help in the overall
propulsion of this truck but I wonder if the weight
of the outboard motor on the back
is really something that we do need.
So let's go back and actually put the outboard motor back
on there and see if we can get
a different test result with that extra weight.
(engine revs)
Under there, over on top, slide it into place.
One screw through, now I gotta remember
in the last video I did where I crossed the channel
or the water pond really is what it is,
or a scale 1/10 size channel,
I actually had to have the motor a little bit lower
so I could plane a little better.
But not too low because then I'd have
that same plowing issue we just saw.
So I want to have it angled up, just a little bit.
Not a lot of wind today so we should be able
to maneuver the waves pretty well.
(door closes)
(engine revs)
For those that are just joining us this is the Toybota.
(loud motor whirring)
So I got a good charge on that battery.
Now the paddle tires should give me the power
plus the additional weight of the motor on the back
and the propulsion, it might even this out pretty nicely.
We'll see how we do.
Beautiful calm day to get out, float around a little bit.
Let's head her into the water.
(engine whirring)
Beautiful, instantly floating.
'Kay so one of the things I notice
about the paddle tires themselves,
is if you go too fast, again it starts spitting water
into the back box.
Check it out.
And that's okay I've got the pump back there,
I'm not too worried about it.
But again, is it worth it, for the amount
of work my batteries would have
to do to have the paddle tires?
Though it is moving faster than it did before
with just the scale tires would we all agree on that?
We saw that in the first maiden attempt in the first voyage.
So I'm gonna bring it back let's have a look and see
how much water is in the back tray
just from that small journey.
(engine dies)
There is a bit back there let's see if the pump will
actually filter it out for us.
(pump whirring)
Yeah it does. (laughs)
This is how I purge the back bed of any water.
So there is a problem of paddle tires
you can only go so fast at the moment
until I build some rear fender flares.
And then I'll be able to use those paddle tires at full bore
until then, I may actually have a sinking problem.
But I don't care I think we should try
and do a channel crossing anyway or a pond crossing.
(engine whirring)
That outboard motor is so cool.
So constant velocity again guys.
Let's get her goin'.
Not too bad, I definitely could use a front bow design.
I know everyone suggested that already
so thank you for your input, I agree.
But in true Top Gear form guys, this is just too cool.
Around the reeds.
Now I guess the true test that I came out here for
even though I got excited and forgot,
was, what if I add paddle power now?
There it is.
It's definitely going faster guys.
Whoa, look at that!
Oh yeah! Right out onto the beach.
And then I can back out again.
Let's get her in position so it's floating well
and then I can get going.
(engine whirring)
(scats)
It's got a long ways to go
because it's gonna start right there.
So I'm gonna put us up on a tripod,
well I guess I can do it one-handed.
Let's see here, constant velocity.
(engine whirring)
So it's going too fast, okay.
I wonder if we're ever gonna see this machine again.
Let's start the pump.
(pump whirring)
Yeah definitely pumping water out.
Not too much though.
'Kay let's get in on there again.
Again captaining with one hand, filming with the other.
It is far over there, can I even see it in the camera?
There it is, I'm gonna have to turn it around
and start bringing it here
'cause the zoom doesn't work that far.
(engine whirring)
Totally awesome.
Whoa I think I'm plowing a little bit too much
so let's turn on that pump.
Whoa! Out of control.
That's okay takin' it nice and slow.
This is crazy for you guys, I can't believe you guys
out here doing this with me.
I gotta zoom back on the camera a little bit
so you can see exactly how far
away this is I'm trying to pilot the boat.
Whoa, kinda wants to capsize a little bit there I noticed.
I wonder if I've taken on quite a bit of water.
(engine whirring)
Turning on the pump, yeah I can see we're spritzing
out some water for sure oh I see one
of the pontoons might be completely underwater.
I don't want to get any water into that outboard engine
just like any usual outboard engine
you don't wanna get water into it.
Just kinda puttering along here.
Looks like we were able to eject some water
and we're getting, there's some more water right there.
(laughs)
Will you look at all the water we'd actually taken on?
It's still purging water.
That's quite a bit so while it was far away I guess
I had too much throttle power going
and I took on a ton of water.
That's okay it makes for good onboard footage.
I'll turn the pump off,
looks like there is no more water to be pumped out.
Still under constant velocity I'm gonna zoom the camera
back so you can see where we're at.
That's a Toyota Land Cruiser 1/10 scale my friends,
12 pounds of radio control amphibious vehicle.
Come on that's gotta earn me a like, click, and a share.
Hey what do you think?
Outboard power I do have about 13 videos thus far
about building this truck and the different missions
we've had with it so far.
I know any builder, roboticist, or heck just anybody
who's interested in this kind of tech,
there you go a floating truck with an outboard motor.
Amazing, a little jittery, a little bit far away too.
Let's get you back down to the beach
and we can drive this thing back in.
Again the farthest point I could find.
We're totally gonna get to shore over here.
Now if I turn it off, outboard is off.
Propulsion is all in the paddle tires.
Gotta be careful here.
I think we were all surprised in the beginning
when the stock tires had actually...
(laughs)
Look at this! The paddle tires actually sunk!
And yet the back, gotta be very careful here.
That's a win, okay. Pump's not workin'.
(engine revs)
Paddle tires and prop power wins.
Check it out, so those paddle tires
though they are very effective they do throw quite a bit
of water up the sides so I'll have to make some sort
of fender flares to protect it.
But there you go my friends, the Toybota
for the 2nd time making a huge journey all the way
across the pond for you guys.
Hopefully you're entertained, thank you so much for
tuning in I hope we got a like, click, a comment down below.
What do you think of this hair-brained project?
Did you follow all-along or this your very first episode
of the Toybota or RC adventures?
My friends, we'll see you in the next episode.
Get outside and have fun with the hobby of RC.
You know I do. (engine whirring)
As a side note for all those wondering
even though this kind of like an after-show thought,
everyone was wondering what would happen
if it completely filled up.
There it is, full in the back.
Motor basically underwater, everything waterproof and fine.
The only thing that really happens
when we have a full back tray,
is that it maneuvers so much better. (laughs)
Turns on a dime and those flotation pontoons,
they're awesome.
Come on back to shore buddy.
Look at this, plowing perfectly.
(tires skidding water)
Ah, power, there you go.
Gotta do it the right way of course.
(laughs)
(engine whirring)
