2017 - !Arriba!

[Functional Artist]

Did I ever tell ya the story about the guy who took all of his clothes off & sat on a cactus?
...he said "It seemed like a good idea at the time"

Ya, my wife didn't like that explanation either

I had to try again
...so, I tried a few runs "in the grass"
(softer landing)

My wife wasn't happy about those...either
...alright...alright...I'm done

* Hold on to your Hat tests are "officially" over
...done...finito

But, it was fun

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

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

TBH
When I test drove the !Arriba! kart (back in April) with the (2) ZY1020 motors
...I was quite disappointed

The kart seemed a lot more "peppy" (last fall) when I test drove it with just the (1) MY1020 motor

"Jumpin' to conclusions", I immediately blamed the ZY motor's (being clones, I guess)

But, now I have come to find out that (1) battery
...or possibly (2) of the batteries, that I was using, had/was "goin' bad"

I think, that's why I was so surprised, when It "poped a wheelie" so violently, when I did the first "Hold on to your Hat" test

I wasn't expecting those ZY motors to be so powerful
...compared to my earlier test drive when they didn't seem very "peppy", at all

So, I'ma gonna re-install the (2) speed controllers & see how "peppy" she is with a fresh battery pack

 

[Functional Artist]

This kart was specifically designed to "pop wheelies"
...super short wheel base (~28")
...powerful, dual ZY1020 48V 1,000W motors
...even, weight biased, by mounting the battery pack behind the rear axle

But, it didn't perform as designed
...come to find out, due to unforeseen circumstances (a bad cell or 2 in the battery pack)

So, lets try this again
...(2) fresh motors/controllers, from Alfa Wheels (~$100.00 ea./$200.00 total)
…& (4) fresh 12V 12AH batteries, from Mighty Max (~$25.00 ea./$100.00 total)

First, we gotta get rid of these dinky sprockets & install some #35 "Power Curve" sprockets
…& can't forget the stickers

Then got 'em mounted & adjusted

Next up, is connectin' the electronics

 

[Functional Artist]

First, I had to crimp some terminals on to the on/off switch wires
...(2) for the left motor & (2) for the right

Made a new "hatch cover" for the back
...a piece of plastic from the back of an old TV
&
Cut in a fuse holder & a covered charge port
...mounted both speed controllers
...then. mounted the whole unit on the kart

 

[Functional Artist]

Then, I dropped (4) 12V 12AH SLA's in the battery box & finished connecting the wiring
...battery to controller
...controller to motor
...on/off switches to controller
...& the charge port

Bolted the rear hatch cover down
…& now, were ready for a "more powerful" test run

 

[Functional Artist]

Now, let's see if she can get 'er "up"
…!Arriba!

Nice work on your electric kart.

I watched the wheelie video (and love riding wheelies), looks really fun !

A couple of times you can see the driver has the natural urge to "steer" during the wheelie because of the uneven terrain.

Does the steering have any electronic feedback to the motors ?

"Does the steering have any electronic feedback to the motors?"

Kinda, there are individual thumb throttles.

The left one controls the left motor
…& the right one controls the right

I guess natural instincts "kick in"
...because I wasn't doing it intentionally

Here is the video of my first test ride with the fresh motor & batteries.

The whole test ride was ~24 min & still didn't deplete the batteries.

I mainly wanted to see how long of a run time I could get out of these little 12V 12AH SLA batteries
...but, I edited the video down to ~12 min (as to not be too boring)

Success!!!!!

Just for fun, I put together a short spot/video about Mighty Max Batteries
...maybe I can get some deals, in the future.

!Arriba! needs a fresh paint job

The rattle can gold looks kool
...but, it scratches really easily
…the wheelie bar is "bare metal"
…& she has some "road rash" from the "flip" last summer
(wasn't really a flip but, more like a flop)

 

[Functional Artist]

A lot of the gold paint came off
...but, he white primer, that I used previously, seemed to stick to 'er pretty good

So, after a bunch of smoothin', & scuffin' & sandin' (my arm is about to fall off )
I gave the whole thing a good coating of the white primer


* Hmmm
I took a break from cleanin' up the main frame on the Atom kart
…& somehow ended up cleanin' up this one

 

[Functional Artist]

I gave the primer a good scuffin'
...& wiped 'er down, with some degreaser

Started off by tipping 'er up on 'er back side
...& giving the underside a coat of gloss black paint.

Let that dry, (~1 hour) sat 'er down gently
...& then, gave the top side a good-n-glossy coat

 

[Functional Artist]

Makin' it flip (safely)

Goin' Gold again, cause it looked really kool
...but, for some extra "bling" I gonna try some Gold-to-Green Color Shifting Pearl
https://www.ebay.com/itm/CX40-Color...e=STRK:MEBIDX:IT&_trksid=p2060353.m2749.l2649

It's the same procedure as the Blue-to-Purple "paint" that I used on Damien & El Mini.

So, I mixed up 16oz. (1 pint) of an automotive type clear
...added ~10g. of the "magic" powders
…& then, stirred 'er up really, really good

* Looked kool, while stirring
...but, I didn't see any green

AWW Since you love ek's you need to make the roll kart

During disassembly, I noticed that the sprockets were lookin a bit rough

So, I cleaned 'em up (didn't paint or prime 'em, just mainly just degreased 'em)
…& then, hung 'em up

For this one, I broke out my "old" conventional spray gun (added the mixture)
...& layed down a decent coat, of this clear with the "magic powders" in it


* I painted a couple of plastic bottles gloss black
…& then, made 'em flip too

I'ma keep 'em on the shelf as examples, of this color over gloss black

I think a kart that rolls over if you hit the brakes hard would be pretty cool like rollgolf
