Yes, the slip ring that connects the track motors to the house. I put a brass washer under the copper tabs so the tabs press a little harder on the ring... and with the grease added, maybe I never have to take it apart again.

This 850 is my all time favorite model to run.

I ran the HK last nite for an hour Greg, the 1st time in a couple of months, and it really sucks in fluent movement compared to the 850.

I tried when I 1st got it last July to make the ch mix work via radio menu & couldn't get nothing. Last nite I was gonna try to adjust some of the valves EPA's similar to how I programmed the 850, and couldn't get into the menu settings. And playtime for the HK hoe ended when the lights flickered & then the pump rpm slowed right down... I tried it today & the pump speed is still slow, like the esc might be junk?! Crap crap crap!

When I get my DX8 rx replacement from Albert, I'll try that Spektrum radio to improve the model's performanace... if it's possible?

Also, when I parked the HK last nite, I noticed alot of oil sitting atop the boom cyls, could the seals be toast already?!

Idk? this is a pretty crappy model compared to the german ones... or atleast mine is. I like this model’s range of motion & reach, but the radio & hyd system is garbage! I might have to change it all before I get it working as smoothly as the 850.

Here's a video with the HK 1st, then the Stahl.

After using the 850 virtually everyday for the last month, these two smaller hoes are kinda slow & unresponsive in comparison.

Would you not recommend the HK model now you have used it a while? I was looking to order it early next year but might leave it if you say its a bit useless.

Joe, do you have a model switch on your radio or do you use 2 radios? I have to get one when spring returns, i want the zwo4 from servonaut but its very expensive, but it fits nice in my radio and it has nice functions, or a cheaper one i can get from CTI, i cant stand to lift my a** everytime i need to change model.

[Lil Giants]

Idk... the RTR kit as a whole by itself has potential! However, with it's crap radio & crap valves, out of the box it will still work, just not very well... maybe mine is just one of the lemons. From what I've read on the norwegian forum, there's a few owners having similar problems.

It's a great midsized excavator with long reach & high lift that's not overly heavy to cart around. It's a little better suited size wise for 14th scale dump trks than the others like Stahl, Damitz or Liebherrmodell. But I think some addtional funds are necessary to improve the low grade rc gear & hyd system for optium performance.

Somebody is working on a mount to seperate the direct mount motor/pump into a belt drive 3:1 reduction. Plus with a change of radio, I'll go from there.

[Lil Giants]

I use two radios Kalle. The dump trks don't require much sophistification as the constr models, get by with a radio a third the price.

The model ID switch within these Spektrum radios is like 5 to 10secs. How long does it take to switch the Servonaut system or CTI?

Ok i see, thats one to do it.

Both the servonaut and CTI is by a push of a 2 or 3 pos switch and you have switched model, i like that and the fact that you only need one radio.

Thanks for the info/feedback..

Do you have a link for the norwegian forum discussion about it?

Joe, you ever had any issues with the worm gear swing on the Vario? When the boom is rotating "downhill" it pulses really violently shaking the whole model. Doesn't seem to be a way to adjust the gear mesh? Talking with Izzy and Travis over the weekend, they were thinking the gear reduction might not be low enough. Thinking the heavier grease they use isn't helping much. Worm gears always work better with lighter oil/grease.

"FrodeS" is the Norwegian rep. As far as I know, the electronics have been changed on the recent deliveries I think they changed the factory putting the machine together as well...

[Lil Giants]

Thanx for the aid Emil.

YEP! I had mega problems with that worm drive, tried many different esc's to correct the problem, but couldn't.

A german friend set me up with a direct mount planetary gearhead motor and that solved all my problems. It's been working perfectly ever since. The only downside is that I had to hack up the body to get the body to sit flush with the floor as the vertical ghmotor is too tall.

I sent him a mail to see what he can do for you.

[pigeonfarmboy]

The tinkerer in me wants to figure out a way to get it to work. Unfortunately Frank didn't have any helpful ideas/feedback.

[Lil Giants]

With the xmas/ny's holidays the last few wks, I haven't accomplished much digging. But I did do some rain dancing.





A slow dribble, maybe a gallon an hour for eight hrs last Friday, got a nice even soak over a large area. It made for sweet digging tonite! Peeled the dirt away like cheese grader.







I had to dig on three sides before popping this boulder out... I just luv the power this model has!



And a vid of tonite's digging fun.

Nice progress!

[SmallHaul]

Cool vid Joe, that machine even sounds powerful.

[Lil Giants]

Thanx guys. With the sound of that pump motor working, I was thinking who needs a sounds system, sounds pretty close to real to me.

And another... poor lighting in this one... using the little guy. I think I will replumb this one with .5mm larger hoses & fittings, just a little too slow for liking anymore.

[trucker n]

hey joe if its to slow for yah you can always send it my way

[dsm4g63punk]

Holy cow that 850 has some serious power! Your reviews on your RC4WD excavator have been very insightful.

[Lil Giants]

Thanx & thanx.

Hopefully my DX8 rx replacement shows up this wk so I can try a different radio in that HK hoe, maybe make it work a little better.

Don't hold your breath Neil.

Good thing you never got the 850 five years ago because you would have put yourself out of work a long time ago..lol
