Re: Metal Hobi MH-245 kit as Hitachi ZX245 excavator

They're mid-priced. All the parts in the photo were $71 shipped. Enough to build 2 with some spares.

Re: Metal Hobi MH-245 kit as Hitachi ZX245 excavator

Trying the drive with side sliders is rough. Instead there are three flight modes:

1.) "Default" allows fully control of the machine. SAE excavator controls on the sticks and the tracks are driven...

Re: Metal Hobi MH-245 kit as Hitachi ZX245 excavator

I really struggled with the hose installation. Flat nose pliers would mangle the hose, and heat would melt the end 9 times out of 10. The German forums' talked about "hose pliers" which sent me on a...

Re: Telemetry data of hydraulic pressure

Got the machine up and running to give this a proper test. Appears to work and is within 10% of an analog gauge. I still need to experiment with location to tap into the pressure side. Currently I'm...

Re: Build an Excavator from Scratch

This is looking great. The beauty panels pulled it all together so well. The metalwork shows your high standards.

The hard pipes on the boom are a great detail.

Re: Metal Hobi MH-245 kit as Hitachi ZX245 excavator

Still doing a ton of painting sanding polishing. Connected the drive and slew motors to try them out, but otherwise no real assembly progress. I did decide to add hydraulic quick disconnects off the...

Re: Telemetry data of hydraulic pressure

Trilliwilli mentioned LUA in passing. Been reading up on it. It's a programming language some TX can run. Just a day ago I was dreading having to write my own app to do some simple math. As it turns...

Re: Metal Hobi MH-245 kit as Hitachi ZX245 excavator

Chassis is painted and assembled. No issues to report, but i did fish a little piece of grit out of the tower bearing. Now it's silky smooth. Decided to leave the tracks raw black so they don't gum...

Re: Telemetry data of hydraulic pressure

The arduino method is looking appealing. Could also be used to adjust/calibrate the output if needed.

As far as boost converters, Dimension Engineering...

Metal Hobi MH-245 kit as Hitachi ZX245 excavator

Here's a build thread of the Metal Hobi MH245 excavator kit. It's the 3 valve mono boom in 1:14.5. Had the 7 valve split boom with plow been available that would have been my choice. This is my first...

Re: Telemetry data of hydraulic pressure

Your DC-16 is absolutely beautiful. The 3D sticks you've added look like a factory option. Very clean integration. Been casually looking for a used Jeti. They're pretty rare in the US and when they...

Thanks for the link to the Brixl sensor. Ofcourse the Germans already have such a thing! I dug through their transmitter manual and it states there are transmitter settings for...

Telemetry data of hydraulic pressure

Been window shopping for a fresh radio and see Jeti has a ton of telemetry options. Battery voltage/current/capacity are straightforward as are motor RPM and temp since the airplane guys all use such...

Re: Looking to get an excavator

I have no knowledge of any machines, but I share your sentiment. I'm skeptical of the Asian import machines. Euro machines are overkill (but beautiful) and difficult to buy. I'm hesitant to blindly...

Re: 1/10 Mining Dump Truck

What's the learning curve like on the pulse TIGs? Seams "easier" than tradition TIG welding, but looks can be deceiving when watching experts.

Re: Less help now a days

still pop in regularly, but none of my projects ever got finished, so I'm far from knowledgeable. Been focusing on 1:1 scale stuff before I return to models.

Re: Liebherr R926compact

The hybrid construction of the boom is really nice. All the hydro/electrical is beautifully packaged too.

I love the zero swing excavators.

Re: Double ended cylinders? Self centering controls?

Nope. It has servo steering in it... and it's still not finished.

I'll bet an arduino could be made to do this, but that's beyond my abilities

Re: Is this hobby dying in the US?

I hadn't really considered this hobby to have fully caught on in the US/Canada. Several small vendors and a couple bigger vendors, but mostly it feels underground. The high price is likely part of...

Re: Need help with fittings please.

Have you checked out SMC? I think the push locks are physically larger than barb fittings with a sleeve. A lot of guys here use barb fittings, although in metric.
