Carson Mini Bull 4x4 (Project)

I got this one new, almost 2 years ago!!
So i decided to show you "people" the project i made in this one!

For the price i got it new, it's cheap.
But it's a Carson, like the evo truck of mine, so it needs some "options".
To bad it does not have upgrade ones.... from atomic or gpm.... but other brands aftermarket fits... (some parts)!!

I Find out that later when got the car... that even stock pieces are all sold out... so no aftermakert and stock... crap! But searching very well the WEB you find some stuff, and other stuff from other cars... and you began a Project....

ok, enough talk, let's go seem them!!!!!


-On the box!


-Back of the box!


-The minibull itself!!


-The bottom!


-If we dont use metal bearings, it is gona brake the conic 4x4 gear. It happened to me... and on the web it happen to anyone who got this little 4x4.Metal bearings for the wheels are the same as X-Mod Gen1. The evo ones dont fit.


-Metal bearings on the front.


-More metal bearings....



-more....


-The original part.... just exploring what to do!!

-Plastic bearings, is not a bearing, its a ring that smokes performance and plastic!

Some small video showing all in stock!!

http://www.youtube.com/watch?v=9JInssnM__0


The pictures that speak for themselves...


-This is the broken gear (the conic one), that will make the crack sound when acelerating.... got one new already. With grease on the moving parts and metal bearings it works fine, and until now... it's not broken!!


-On the diferential the pseudo plastic rings (bearings), on the eye i notice they are a serious problem. So metal bearings are so smooth, so perfect!


-The metal bearings on the diferential! Believe me, a lot of more control and smothenes! Notice the grease and the NEW conic 4x4 gear. This should come like these out of the box...but at least i understand a little bit more of the car.


-The 5 cell upgrade. It runs more faster and more torky.But without metal bearings the conic gear.. becames like on the next video....
I got a video, of this Mini Bull with a 5 cell upgrade and the Crack sound on moving. Let me find it....
found it!

http://www.youtube.com/watch?v=6jKQ7mvwPrg

the bearings are this sizes:
3x6x2.5 = 8 for the wheels
3x6x2 = 3 for the center (4x4)
5x8x2 = 4 for the differentials.....

-Finding the rings to subst for metal bearings on the 4x4 gears/transmission!


-One plastic ring for a metal bearing!


-Studing the original motor and it's places!


-Metal bearings on transmission! Oh yeah!


-Central axle with plastic ring? Hum, gota go!

That is the itens that i bought.
to help someone to!!


-The conic gear that broke.... i only use that. the other stuff was intact!


-Some diferential's to lock in a near future.... or maybe i lock the ones i use (better that way)

After a few months of fun... happens this...



Where is the front end? (bumper)



Then again where is it?
After a few crashes, it broke... so i glued with araldite!



-this is the glue process! Lot's of it to be really secured!



-And this is the glued process DONE!



-Another one, full body!

and since i was reparing the front bumper, i decided to clean the tires and the car...

on the back it was like this....


-In here the tires are cleaned with wd40... hum... not enough clean! and a small clean on the bottom of the car!



-More tire cleaning, all 4.

-Readings i usually now read


-Tires washed with water and soap...

More grip now!

Since i am on the cleaning process...


-Some carnuba wax to make it shine!


-Waxing!


-Back waxed!


-Some engine minor upgrades
(cuted the plastic logo to spread the heat more easly, and cuted one piece of plastic on the comm "like the chili", to help to ventilate and put comm drops)

-Here it is the paper locking the diferencial!


-Since the bearings are out, i clean them!


-After cleaning i lub them with this piece of magic oil :scholar:


-And the locked diferencial in place! "locked only the back one"
And i used black paint, of a marker to know that one is a locked diferential!


-This will help anyone who have this model, to find pieces! :bump:

And since i am playing with it...


-Just making some tire foam to insert inside!


-For a little more traction!


-DIY insert foam... it actually works! Some 10% more traction. And that's a good thing!

Just like in real life, a correct pressure tire is better in several things... a low pressure tire is bader in several things!

....this thing needs more speed!

So what to do?

"i know, it got weak diferentials, weak plastics all around, but it's full working till now..."


-That board, needs first more fets... but not right now!! opcorn:


-Guess what? Yep, Lithium Ferrite cable soldered to the board!


-The Lithium Ferrite Baterys on the car! Note that this board handles max 6v, as a worker on the "carson" site told me. So 6.6v should be ok.... :squint:


-And the job done!

What i noticed first when playing? Well, i need a lot of room in the first place to race this weak 4x4 car!


And a video of it running with the two Lithium Ferrite baterys...

Guess what?

Still not happy with that speed...

So i am making this into a "racing" machine, to smash and wear out/kill gears and diferentials hno:

So what to do?
First FETS:


-It's "4562" fets!


-Stack'em!


-2x3 of "4562" :stirring:


-Soldered! :flame:


-Ready for more?!!

PUM :armed:

I checked and double/triple checked continuity with a multimeter... but when powering fets smoke....
So i got no car...

REVENGE is coming to the DARK SIDE :vader:


Only problem with this excelent car... is that it does not have aftermarket pieces... GRRRRRRR.
This 4x4 car, with alloy from GPM will be a very good base for brushless systems... but there's no aftermarket brand for this "toy". Just the crap "Carson"

So No PCB.. what to do?

Let's see....


-Grab a Z2 from atomic!


-Get ride of that Atomic Stock... very well used even on the evo truck!

Make this..."Motor Break in" used 1 AA cell for 3 minutes.

On this photo is the back of it... notice the 2x2 satck fets (4fets)


-The front with more 2x2 fets. (4fets)


-The proff it's a MiniZ Awd 2,4ghz PCB


-And the search and trial process!

-Tried another way....


-And tied up and geting ready... just testing now!
