china kat

[bigford]

well it got here today!!! post office lady popped it on the scale 34 lbs
in the box.

pic above was with the flash on the one below is the real color


a few thing that need to be pointed first I don't read Chinese and the copy of a copy of a copy

pictures suck in the instruction book. next I bought the kat a1 bf witch I thought meant I get a black base

they shipped the silver. next was the pump motor BRUSHED not brushless like the pic online shows!!

the slip ring wires are so thin compared to the drive motor wires i'm not sure that will work???

the servos are tower pro mg995(digi hi speed) only work one at a time if I plug two in one gets wonky

and the esc beeps(could be a weak batt) the only esc not marked drive I guess it for the turn table

that only rotates in one direction... my viper 15 hooked up goes both ways(again cant read Chinese)

Also watch the hyd lines they dont like too much pressure and tend to shower oil every where when they blow.
I found it was like russian roulette , waiting waiting ...bang ... oh crap. LOL.
But its a start you have an excavator.
now build it .
cheers andy

Congrats on the new toy Mark. im sure your going to enjoy adding your personal touch to it. . Is it just the pic or does the upper structure look like its leaning back and not level?

[bigford]

upper was just sitting the base with the drivewires itin the way
i wanted just the empty machine BUT they now do not sell it
that way. it is all aluminum and heavy it gave the single firgelli
a work out lifting the lowboy up

Congrats on the addition. Just as much fun setting um up as running um!! Take your time as you'll be running her soon enough. And it's gonna take us a while for rest of this snow to melt and thaw ground!! My backyard pit is almost melted but rock solid ice under a nice slippery mud layer! Looks sharp all painted up nice. Did they send cat decals also? I remember someone saying they have on earlier models.

My KAT also did arrive with the superstructure bent down in the back. I am following a series of chef Gordon Ramsay's Hells Kitchen at the TV now, and I can't avoid imagine him taking a trip to the KAT fabricators 'kitchen'... 'It's all ****, don't you have ANY pride in what you doing?! How DARE you present this to your customers at these prices?!' Hehe..sorry, good luck with the machine. It's possible get it going with some DIY effort)

Congrats on your new addition she's looking good

[cosworth34677]

so is worth getting or is better to get the magom hrc one?

[bigford]

magom never answered my what size is the machine .
looks like a older case excav. the kat looks like a cat 345L

[cosworth34677]

ahh ya they are hit or miss with emails....

[bigford]

here is the pic of the slip ring wires
top wires are servo then slip ring then motor and battery wire

the slip ring wire is so thin I cant see power going from the esc to that then to the drives

[bigford]

a little vid of the rotation seems smooth

You must be stoked! I think they are a nice looking machine given the price. I'm sure with some tweaking it will work great too! I know you just got it but what are your impressions on the track drive motors? The speed looks good but do you think they are really torquey? I have almost ordered a pair a few times to replace the motors on my EC300 but keep putting it off. I am tired of tearing up the gearboxes on my current motors though and need something new before the summer show season. My excavator is over 50lbs though so they need to be quite powerful.

Thanks for the input!

kinda hard to say reg it climbed the grass lip off the driveway with no problem
and up onto the lowboy the same way. all the motors are marked 12 volt and
look like drill motors

[bigford]

like it was said good bang for your buck BUT the Q/C is lacking

the drive hub is steel along with the fixed idle wheel and guide rollers


lock nuts on some things and others just have plain nuts and no Loctite no berring or shims
the gaps on the hydraulic are silly need spacers every where

[bigford]

the boom and dipper and bucket



no spacers to align the two cylinders from the base to the boom
