da mad maori

ive been contemplating this thing for a while...

the biggest hold back for me was the amount of power needed to steer something this big and heavy
after much research on the net... i built a high powered servo..... out of a window wiper motor and an Hbrigde motor controller circuit

the frame in this vid is not going to be used .....
the suspention doesnt move... the front arms are one peicse

anyways this is the the begining.. hopefully progress will be good

enjoy

Looks like you started with a mini ATV? Anyway, I tried something like that last year but lost interest due to other projects, I still have all the junk here so maybe if you do something nice with it I'll be encouraged

Nice job with the steering setup.

A tone servo is all that you needed. If you need something bigger then it's time to shed some weight. A tone 050 is plenty.

da mad maori

over $300aus for a smallest tone servo (050)

$770aus for the bigger one to be safe

OR

$70aus to build ya own thats as if not more powerful than the bigger tone ????

a simple decision for me

(plus my knowege of servos has gone from 0 to just a little more than 0 )

What are the dunlops from?

it's gonna need some serious hp

da mad maori

cheers mooman and others
the dunlops are wet weather go kart tyres believe it or not lol $15 from ebay, 1 hour use.

Wow that is looking really good. Good work on the sevo, It turns those big wheels with ease [X(]
BTW, it seems a chainsaw engine would be right at home on that chassis

Hey Bro,

Don't get standard alloy go Kart rims (like I did [&o])

Is this what comes after you have experienced 1/5 scale? I know there is 1/4 scale, but your scale is a little differant. Great vid I just had to check it out.

A Tone 105 servo is The biggest you can get. Plenty of power @12 volts(5000 oz. Loose the weight and you can use a Tone o50. I do on another application no problem. Weight is you biggest enemy. I built a 1/4 scale buggy for $250 and it uses a 220 oz servo for steering. I never pay retail for my stuff. 50% or less. Free is the best.

update;
slowly peicing together.. just tacking everything for now until its all moving the way it should

changed to location of the engine and now bolted to the rear swing arm... (no slacking chain issue)
just have to shorten the chain now





getting overall shape of the cage









got my rims today........ my MCDs new zenoah came in too.

Mudgy

Looking seriously Industrial grade!!!
I'll bet it will SHRED when its running

da mad maori

cheers man
although im beginning to think this is abit bigger that a 1/4scale
