Hitachi Zaxis 210

I've just bought this from Ole (Vforce). Buildthread in English: http://www.scale4x4rc.org/forums/sho...hlight=hitachi

It's pretty much done. Just need some paint on the cab and some more lights :D

Re: Hitachi Zaxis 210

Wow,very nice excavator ,nice buy,looks like a nice project and fun !!:)

Re: Hitachi Zaxis 210

Does Ole still have his dump trks or is he out of the hobby completely now? :( I seen him trying to fly helicopter during the holiday season... is it in pieces yet? :D

Have you put an esc on the hyd pump to radio mix with the valves Emil?

Re: Hitachi Zaxis 210

He is out for the moment, but not for ever :) I guess he's too busy cruising in the 60's Caddy he bought...

I haven't mix the ESC with the valves (yet :)) The pump is turned on and off from my radio. I guess mixing is more useful on loaders, since they are driven quite alot without using the cylinders.

The tracked loader is sold btw, Would've been nice to keep it, but it was too much money tied up in R/C equipment.

Re: Hitachi Zaxis 210

Correction: Now the valves and pump are "mixed together". I currently have 9 mixes in use (hyd + sound). Really looking forward to try it in our club house.

Re: Hitachi Zaxis 210

That's a nice machine! I remember following the build on Scale 4x4. It's good that it found a new home with you. I hate to see guys put so much work into building a great model and then sell it. At least it hasn't disappeared from the forums!

Re: Hitachi Zaxis 210

Your lil Hitachi looks great, it was about time that cab got painted! :)

Re: Hitachi Zaxis 210

It's been a long time since this got some TLC. I finally got some windows made during the weekend. I also made a roof rack and added a coulpe of lights ontop of the cab. Next step is to correct the aweful orange paint on the cab.

Re: Hitachi Zaxis 210

You will enjoy having the ripper, only down side, they don't stay on very long.
Then it's time to put the bucket back on. I seldomly leave mine on the mini excavator
More than 5-10 minutes.
Cheers, Neil.

Re: Hitachi Zaxis 210

How long does it take to make a change with that mechanical quik-tach?

Looking good Emil! :cool:

Re: Hitachi Zaxis 210

Less than 2 minutes to pull the safety pin and rock the jaw, with the crowbar.
And 1 trip out of the cab for each attachment.
Yes Joe, I know you were asking Emil, lol!
Cheers, Neil.

Thanks for the comments guys!

The change takes only a few seconds :D I´ll post a video.

Re: Hitachi Zaxis 210

So that allen screw is push/pulling the pins at the back? Pretty slick! You keep the wrench in the cab? :D

Thanx for the vid. :cool:

Re: Hitachi Zaxis 210

Short hours at my regular job today :)

I bought a new motor for the pump on my way back home. It was also time for (an overdue) oil change.

Re: Hitachi Zaxis 210

Which one is the new one & what are the specs of each motor in the picture?

Re: Hitachi Zaxis 210

1100kv, hmmm, that's quite a bit... do you have the epa turned to 50-60% max? Are you running 10cell or 3s?

What were the specs of the other brushless motor & why did you change it out?

Re: Hitachi Zaxis 210

The original replacement motor from Leimbach is spinning on 12.000 RPM at full speed. That equals to a 1080kV motor using 3s LiPo (as I am).
I´ve set it up to run on 30% without load, and up to 65% with fully open valves. All four functions are mixed with the pump using the radio (Spectrum DX10t).

The old motor had similar specs, but it had some bad bearings. The new motor is bigger, thus I expect it to have more torque.

I´m looking forward to really try it in the dirt :)

Re: Hitachi Zaxis 210

I've not been fully satisfied with the capacity of the hydraulic system. Leimbach has made an upgrade kit for the Medico excavator that I bought. I'm pleased with the initial testing :) Old pump was app 380ml/s, while the new one is 600ml/s.

Re: Hitachi Zaxis 210

The only change is the pump? Didn't increase fittings or hose ID too?

Quite a change! almost too quick, but not hard to program curves for valve adjustment & pump speeds. ;)

Re: Hitachi Zaxis 210

New fittings on the pump, and new hoses between pump and valves.
