Metal Excavator - Magom HRC MG1.4

[Digger_Bear]

Recently treated myself to this RC model. It comes in various versions of completion but I picked the full metal unit and hydraulic system for it which left me with adding electronics, radio, final assambly and painting.

So here's some pictures

Hopefully next pictures will have paint on.

[Rvjimd]

Oh, it doesn't look like it will be that fun, I think you would be better off returning it before it gets dirty. :p

On a serious note, thanks for the nice pictures! Neat to see what to expect out of the box on this sort of thing!;)

As I review the photos, I have a question. How do the pins in the tracks go in and out? I can't tell if they are threaded bolts or pins or what? Thanks!

Jim

[RCP57]

Thanks for posting these pictures. It is nice to see what the actual kit looks like. Keep us updated!

[Rakthi]

WOW nice kit. Going to give you loads of fun building and then mucking about!

Love the slewing mechanism they have build in there.

Keep the pics coming!

Hi Jim,

Tracks are held together with a pin and c clip. I try take some close up pictures.

[Fierce Hitachi]

Looks pretty cool, what was the total cost including postage to UK? Also I'm from the UK too, which part are you from?

[bigford]

how big a machine is it? cat 320,345

[Digger_Bear]

Looks pretty cool, what was the total cost including postage to UK? Also I'm from the UK too, which part are you from?

Worked out £1307 with shipping then credit card hit me with £38 for not buying in £ :mad:

Took just under 2 weeks from order to dispatch then 1 week to deliver.

I'm West Yorkshire, what about you?

[Digger_Bear]

how big a machine is it? cat 320,345

Not certain what size it's trying to replicate.

dimensions are on bottom of this page http://www.magomhrc.com/en/mg-14-metal-excavator-114/425-mg-114-full-metal-excavator-kit.html

I'm planning on painting it like a Hitachi ZX350

[bigford]

ive asked mongom 3 times what model it is
but never got a answer. my kat is a wedico 345
knock off.

Cool, I'm Lancashire so practically just over the field :) Keen to see some pics once its been pained as I'm a fan of the Vario Hitachi and this one looks like it will be very similar. Be great to get a dig going in the garden some time. :cool:

[Digger_Bear]

At moment they seem slow at answering emails. I Last emailed them Friday and got a reply Tuesday saying they really busy at the moment and vaguely answered my questions.

My guess is it is a upscaled bruder cat excavator.

[Digger_Bear]

:) yeah not far. Painting not my best point so really hope can do a good job.

[Digger_Bear]

Okay not the most scientific method but compared pictures of the cat 320 & 345 and I recon this is more 345

[mcCracken15]

Nice! They are really getting better and better! I love that it takes less than a week to ship across the ocean and to my door step here in oregon. but please some info on the tracks i am serious about buying them apposed to building some? And a quick measurement of the drive sprockets please! I love the new look! You think its the sane rams as before just with bigger inlet and outlets? Mine are 3mm still. keep the pics comin and abd info on how well its built!

[Digger_Bear]

Okay here's some pictures of the tracks, track pins, rams

[Northern Farmer]

Great pictures I've been considering this model or the Eagle machinery 4200xl excavator. The price is good at 2082$ in kit form with electronics.

[mcCracken15]

Thank you so much for those measurements. i will be tuned in for updates

[michael_90brown]

Awesome will be buying one soon

[Digger_Bear]

It's been slow progress but finally got a start on the painting.

Looks like fun and should be great fun when you get it running! Thanks for the pics!

Jim

[Digger_Bear]

Well rained tonight so no chance of any more painting :TD

But I did make some progress.

Put tracks back on the base

https://lh3.googleusercontent.com/-SaGz_4FpDR8/Vcp5oJN5pxI/AAAAAAAAIiI/lDfOwh7Q3EY/s640-Ic42/IMG_2903.JPG

Installed a better slip ring

https://lh3.googleusercontent.com/-VVuhLAlOFRY/Vc0EqutCtJI/AAAAAAAAIlU/1ZwcHvCiwsc/s640-Ic42/IMG_2909.JPG

The excavator base attached to the track body.
At this point I decided to add some lock thread to the bolts holding it all together.

https://lh3.googleusercontent.com/-C3dxtPlEZbM/Vc0EqmeN9gI/AAAAAAAAIlU/sBRfsdQF0tM/s640-Ic42/IMG_2910.JPG

Good looking machine

[avel]

Hey, thanks for posting!
Magom has really upped their game since about a year ago.
I've completely forgotten about them.
They have a beefy looking hydraulics kit for the Carson LR634 crawler loader. I've been looking to upgrade the cylinders in my model.
That's a nice excavator! Thanks for sharing.

Agree looking on they Facebook page they have a lot of new toys in the pipeline. And the hydraulics seem to moved over to brushless motors and oil instead of antifreeze. The pump in the excavator kit is jung hr7 so i'm happy with that.

[Lil Giants]

hr7 - what is that in terms of ml/revolution?

[Digger_Bear]

Not certain. On the Premacon website the hr7 pump States 900ml per minute.

[daddycool75]

I hope this helps !!

No didn't get chance to do any work on it over the week end. Need some decent weather to carry on painting the boom when that's done I can start to put back together and hook up the hydraulics.

[mcCracken15]

so by chance can you tell us where you purchased that nice slip ring from?

[chris deacon]

Out of a matter of interest. Did you get all the plastics in the kit too? Windows and interior??

[Digger_Bear]

No it was just the metal shell. Can buy the interior separately but I didn't see that until after I ordered. Going to have a go at making my own interior.

[Digger_Bear]

Tonight been doing more painting.

First I wet and dry the bits to remove some of the roughness etc, then assembled the boom and bits

https://lh3.googleusercontent.com/-2tYMVjfTxl4/VdzgpSPwrVI/AAAAAAAAIuA/1T-P94RJWJw/s512-Ic42/IMG_2988.JPG

Several more coats of paint

https://lh3.googleusercontent.com/-GbLBy0kO-04/VdzgpR_vBmI/AAAAAAAAIuU/fzuorJF0KfI/s640-Ic42/IMG_2992.JPG

Next.

Made a bracket to hold the slip ring in position and help keep pipes and wires out of the slew gears

https://lh3.googleusercontent.com/-e89DyAp1gFI/VdzgpelNUtI/AAAAAAAAIuU/sJi2w5QR-JY/s640-Ic42/IMG_2990.JPG

Added servos to the valve unit

https://lh3.googleusercontent.com/-hkNbXQtPOFY/VdzgpVHnJGI/AAAAAAAAIuU/zhr30-lkXnk/s640-Ic42/IMG_2989.JPG

Pump & valves secured to the base

https://lh3.googleusercontent.com/-Gd0nIML7yl4/VdzgpcmH5bI/AAAAAAAAIuU/cRHJVtx6ZTU/s640-Ic42/IMG_2991.JPG

Played around with internal setting out

https://lh3.googleusercontent.com/-rMuKxXONilA/Vdzgpb11fGI/AAAAAAAAIuU/jM7Y0wx-BFs/s640-Ic42/IMG_2993.JPG

[mcCracken15]

ive got a bit of a problem with mine cause i built it from scratch and i have alot of support brackets going threw the center which took up all of my space. right now i am debating on switching to m5 fittings from m3. my rc4wd valve is all m5 the rest of my stuff is m3.

[Scottyboy436]

What controller and reciever are you using as im looking at buying one ?
Is the quality good for being cheap compared to the other models out on the market ?

[Digger_Bear]

I don't know about the m5 or m3 this is my first hydraulic model so haven't a clue which is best.

Radio at first planned to use a turnigy 9x (with updated firmware) as I have one and provided 8 channels with some nifty mixing channels etc. Then bought a turnigy 9xr pro cheap off eBay basically basically same but few more bells and whistles but same 8 channels to control.

Quality of the magom. It looks like it's a nice engineered and built piece of kit, however I have found bits have come loose even before use so had to start removing bolts and grub screws to add lock tight. And at moment no instructions so got to make it up as I go along. I will know more when I get it running.

[Digger_Bear]

No painting at moment, need to wet and dry boom & bucket before moving onto clear coating it all.

So on with the internals

First plumbed up the pump to the valve block and figured the correct direction for the pump to ESC connectors

https://lh3.googleusercontent.com/-8CizAZwIAfk/Vd9xHZyChJI/AAAAAAAAI0M/im7XD2YW2wc/s640-Ic42/IMG_2998.JPG

[9W Monighan]

Can you give me some information on that electronic board shown in one of the pictures.

[Digger_Bear]

Can you give me some information on that electronic board shown in one of the pictures.

Sure it's a IBU2 which is a control board for 1/16 scale tanks. Heres spec page

http://rctankelectronics.weebly.com/products.html

I use them in my tanks and are great boards so decided to use in the excavator to control the tracks, slew motor, lights, sounds and exhaust smoke unit. It also has customable sounds so I can make it sound however I want.

[Digger_Bear]

Nice job, the wiring looks great!

[Supermario]

Very nice! And very impressive. Im a fan of Magomhrc. Very impressed with how far they've come in the last 3 yrs. must be doing something right because they're growing and getting more serious for sure!

[Digger_Bear]

Thanks for the kind remarks.

Question on the hydraulics. Since the resivor tank is small how do I fill up the system with out running pump dry?

Any comments on add oil and getting air out welcome total newbie with this stuff.

Cheers

[Rakthi]

These are the steps for the Fumotec Komatsu 490LC. Should be similar. After each movement of the pushrods in the cylinder I would top up the oil if the tank is really that small. I was surprised at the total amount of oil needed.


First steps for hydraulics commissioning:
-Mount all nipples using liquid gasket
-Disconnect the cylinder pushrods from the Excavator arms, so there is no load on the cylinders.
-Looking from the front of the excavator, make sure that the hydraulic pump runs in a clockwisedirection.
-Open (anti-clockwise) the ‘max’ pressure valve (the little brass valve) 2 or 3 turns
-Start the hydraulic pump with about 15-20% rpm
-Close the ‘max’ pressure valve slowly until you reach 10-15 bar on the pressure gauge.
-Now open the first valve a small amount in each directions, this should release the sealing rings in the cylinders (in case the cylinders have been stationary for a period of time). You should see the cylinders moving in each direction.
-Once the cylinders are free to move then operate the valve to move the cylinder to its end position. Now operate the valve to move the cylinder to the opposite end of its travel, you may hear air bubbles returning to the oil tank.
-Move the cylinder 5-10 times from one end position to the other until there is no air bubbles returning to the oil tank (you should see the air bubbles in the yellow tubes)
-Repeat this procedure for all other cylinders
-Once all the air has been eliminated from the system you can reconnect the cylinder pushrods to their mounting points. Increase the pressure in the hydraulic system to 20 bar and you should be ready to move the excavator arms.

[Supermario]

Congradulations on getting her running.:cool:
Sounds like the pump is cavitating every now and then? Still got some air perhaps?

[Digger_Bear]

Yeah I think still some air in system so will try work it out of the system.

[Digger_Bear]

Update. Started on the main body.

Decided to add a fuel inlet which will actually be the smoke unit filler tube ;)

[rc_farmer]

I have the same pump as you. Question....looking at the way you have it plumbed in on page 3, have you blown any lines or have you adjust the pressure? Also, is the pressure adjust screw that big brass screw on the bottom of the tank?

Thanks

[Rimrock]

It's a practical thing with such a small hydraulics tank, and I'm sure there is just enough oil in it in order to make the machine run smoothless, but what about heat development..? E.g Premacon use a pretty large tank, and much extra oil in the system, as a simple way of cooling.
Looking forward to hear how these valves and pump unit performs after some hours of running. I see no filter? The pump itself is well known to perform great, but I'm most curios about the valves, how leak-proof they will be. They are quite much cheaper than e.g. Premacon, naturally, and I might want to test them in my own machines in the future.

[mcCracken15]

I can't wait to see this thing in full color!

[Digger_Bear]

Hi guys,

Sorry for lack of posting been busy.

Not had too much run time but so far haven't blown any lines off and I only hand tightened the nipples. No leaks as yet but not had much use on any demanding ground.

Painting nearly done, just clear coat left to do and transfer to be made and added. Got some pictures so will upload when on my computer.

[bigford]

your first test run was alot smoother then my kat thats for sure

[cdm]

I've read very mixed things about their new line of hydros (the old one I wont comment on, we all know the deal). Can you let us know what happens after say 100 hours of runtime?

[Digger_Bear]

Not a big update, but more painting so here’s some picture of progress.

I try my best to, 100 hours run time could be a long time waiting but will share any thing which crops up.

[RCTech9]

Looks like a great machine you have built.

Split pipe as it comes off the pump. Thing is I didn't have pump running that high and I was indoors showing it off so wasn't putting it under any real strain.

Will have a clean up another evening see if anything looks wrong. For now I'm thinking some clear laquer coat overspray might of weakended the pipe as it's gone at that place.

[rc_farmer]

Hey Ian......EXACT same problem.

[Digger_Bear]

Hi Rob,

Seen yours did your pipe balloon up first, think my it just popped open.

Now replaced and running again.

Today I got to play in the garden.

So bit of weeding :DO

https://lh3.googleusercontent.com/--189aS1A4Lc/Vj9JGrvWn7I/AAAAAAAAKFc/d-XV1O3yXKs/s576-Ic42/IMG_3380.JPG

Ran good, struggled pulling the grass/weeds out which I would expect. Gone through 2 x 2200mah 3S batteries running pump at 20-40% stalling the pistons with the load and no oil leaks pump and pipes only slightly warm so happy running okay so far.

Until!

https://lh3.googleusercontent.com/-t-qlDTAPtSg/Vj9JGk1VcwI/AAAAAAAAKFc/dR6dWV0H0gU/s576-Ic42/IMG_3381.JPG

Thought the grass had locked the tracks and caused a link to snap but looks like a simple derailment although too much tension in the spring to pop back on so looks like I need to open up the track to get back on :BH

But all learning curve. Don't over tax tracks when crambed full of grass!

[Digger_Bear]

Also this evening been playing with the settings on the radio.

So now I flick a switch it starts the pump at about 10%. Then

Main boom arm when called for adds 20%
Boom to bucket adds 10%
Bucket adds 10%

So overall the pump is running between 10% throttle at idle to a max 50% throttle with all 3 pistons been used.

It works good but way too fast for me who was running it down at about 20-30% so will make another profile with less power so I can get use to it then switch back to this version when I need the power.

[Digger_Bear]

Just got a email back from Magom as i could not see the glass for the cab on there site but apparently they do it but they have not put it on there yet.

[Digger_Bear]

Well be playing today, all running good. With the new settings to the pump running on demand getting much longer run time no issues with heat.

Also added a setting on the radio where flicking a switch on it automatically adds 20% throttle to the pump, bit like a boost option.

[Azonic]

Great job on the paint and details!

[Northern Farmer]

Great job on building the excavator it looks awesome :eek: You must be proud! :D

[Digger_Bear]

Thanks for the nice comments guys.

Yes I’m very happy with how it’s turned out, and now using it more to dig stuff I’m slowly getting using to controlling an excavator and having a lot of fun.

Will post more videos when I do them.

Where did you get your new slip ring?

[docfcybo]

Hello! Great work on your 330D! :)

I've just bought one from Magom, but need your help about LEDs: what type and power LED have you used? They are very compact, yet pretty shiny! :)

Hi all, not posted on the forum for ages.

Where did you get your new slip ring?

Can’t remember. It was from one of the China stores.

Again I can’t remember. Something like SMD 2.4x2.4mm white.


I got to admit I haven’t had much time to use the excavator over the year (been busy with other projects) but will point out issues I have had.

Not long after completed it the piston for the bucket stopped working, it had blown a seal/gasket. Magom sent replacements and the piston was easy to take apart and repair all in under half an hour. Not certain if the failure was manufacturing issue of my lack of skills as a new operator, running too high pressure digging into very hard ground. It happened, but hasn’t since so I’m not too worried and was a quick repair once I got replacement parts.

The tracks aren’t that great driving over rough terrain, don’t grip in dirt and spinning on spot tends to derail a track. Again this might be me, digging in sticky dirt (most the videos I’ve seen RC excavators are on sand or dry dirt)

The weight of the model seems light as the model tends to move rather than bucket through the dirt (my sticky dirt again). With sand this isn’t a problem.

Overall still happy with it and glad I bought it. Just shame I haven’t had enough time to use it over the summer.
