2017 - !Arriba!

[Functional Artist]

Had a small warm spell (like 52*)

Got Arriba out for a quick spin around the neighborhood

Brought the GPS along to gather some speed data

to document how fast she is - currently

(with just the one 1,000W motor)

Instead of doing a series of videos during the build

...for this one

I did a "slide show" still photo type build video

...added some music for your enjoyment

[Functional Artist]

It's done eh!!!!

Yup,

...wudda you think?

...started with a piece of pipe on Oct. 9, 2017

Less than 3 weeks start to finish

But, wait there is more to come

stay tuned

 

[MTNSleder]

U win for fastest build time!!!

Had a small warm spell (like 52*)

Hey, that's our winter time temp LOL!!!!!!!! Very nice!!! Looks a bit cramped but it sure runs great.

 

[Functional Artist]

Looks a bit cramped but it sure runs great.

Set up like them "old school" karts

...knees up in your chest -n- all

But, it's not really cramped

just

...short sweet & to the point

...& yes, it runs very good, even off road


* I can't wait to experience the performance with the 2nd motor

! ARRIBA !

 

[Functional Artist]

Here is another Desteny rides video

She has had some steering issues

It seems that

...by only running (1) motor (on the left side)

...with lots of power/torque

...& having such a short wheelbase

...& with the rear wheels being so far forward

...& with the frame being so light


the Arriba kart tends to (with her on it, not so much with me)

...lift the front wheels & lurch toward the right

...& doesn't like to turn left at all

...especially on grass

Yea, for indian summers

It was like 60* around here over the weekend

My oldest daughter Sierra is usually workin' when me & the littler ones have the kart's out.

She was off this weekend so, she got to join the fun too

Spring has sprung

I got the !ARRIBA! kart out

Time for Chapter 2 Dual Motors

I got (2) of the 48V 1,000W motor kits from Alfa Wheels ~$100.00 each
https://www.ebay.com/itm/1000-W-48-...roller-keylock-Throttle-charger-/161881812471

These are kinda kool kits for ~$100.00
Includes the motor, speed controller, throttle, key switch & even a 48V 3A battery charger

https://www.youtube.com/watch?v=RE4StgbNdRc

 

[Functional Artist]

First, I switched the #25 chain sprockets on both motors with Power Curve sprockets for #35 chain

Then, I removed the left (MY 1020) 48V 1,000W motor & replaced it with a ZY 1020 48V 1,000W motor & I also installed a (matching) 48V 1,000W ZY 1020 on the right side

I also installed a (matching) 72 tooth sprocket & a piece of #35 chain on the right side

The drive sprocket & the driven did not line up
...looks to be ~1/4" off

Used the chop saw to cut some assorted spacers

Then I got 'em all adjusted up

https://www.youtube.com/watch?v=ynqP0iDZoh0

 

[Functional Artist]

Now we gotta hook up the electronics

Removed, the MY 1020 speed controller, off of the back cover
...installed the (2) ZY 1020 controllers
...installed a 50A circuit breaker
...& the charge port that came with the motor kit

Connected, an on/off switch (on the dash) to each of the controllers "lock" plugs
...a motor to each speed controller (wired so the left one spins CCW & the right one spins CW)
...the (2) thumb throttles
...& the charge port plug

I grouped
...the (2) battery positives (+) together
...& the (2) battery negatives (-) together
(the ones coming out of the speed controllers)

Then, connected a piece of black 10g. wire, to the 2 wire negative junction
...& ran it to the battery packs negative (-)

Then, connected a piece of red 10g. wire, to the 2 wire positive junction
...& ran it to the input side of the 50A circuit breaker

& then, another piece of red 10g. wire from the circuit breaker to the battery packs positive (+)

 

[Functional Artist]

I mounted the left thumb throttle on the left side of the steering wheel & got it all adjusted so both throttles rotated the same (had the same throw)
...then I noticed (it's upside down)

Both of my thumbs are not on the left side of my hands

Easy fix, just flipped it over

 

[Functional Artist]

Double checked everything, propped 'er up & made sure that the wheels were off the ground

Flipped
...the circuit breaker "on" (nothing popped or is smokin')

Turned the left switch "on" (still lookin' good)
...& gave the left thumb throttle a twist
Yup,

Turned the right switch "on"
...& gave the right thumb throttle a try
Yup,

Time for a test drive

https://www.youtube.com/watch?v=WC2EPqBMkJA

Me & the kids rode 'er around for at least 20 min or so before dinner
...then plugged the charger in when done

 

[Functional Artist]

I tried a "Hold on to your Hat" test with the !Arriba! kart

So, just a 48V battery pack, (2) 48V 1,000W motors & a "beefy" switch

"ED BA" "UN DA LA" "!ARRIBA!"

Wow!, just Wow!

[Functional Artist]

I think we should install some "wheelie bars"
...before the battery box disintegrates

But, how "high of a wheelie" do I want to pull/sustain

I set the front of the !Arriba! kart on a tire to check "ride height"
…front axle ~9"

Naw, that ain't enough

How about up on (2) tires?
...front axle height ~18"

What about the battery box?
...looks to be ~ 2" (off of the ground)

Yup, that should work

 

[Functional Artist]

So, a couple of ~3" wheels should work

Mounted/bolted them to a piece of steel
...so their removable/changeable (if necessary)
…& to help keep 'em aligned

 

[Functional Artist]

I got the wheels mounted to the steel plate
…& the plate welded on to the kart

Time for a test drive

The tricky part to a wheel bar is the BAR part. Those new wheels have to extend out at least 2 feet. Reason is you create a whole new "wheelbase" when they are in use. And the rear wheels then become the front wheels. With front wheel drive you have torque steer. And with the rear wheels 4 inches behind you will turn and turn quick.

Also, with them that close, you could very easily flip alllll the way over because now those rear wheels are a pivot point.

Wild ride for sure. Knee pads and elbow as next time. Lol
