New Eagle Mach Excavator 1/14

[Kaan]

it's offical now

http://store.rc4wd.com/114-Scale-Ear...TR_p_5187.html

2700$ plus 450$ shipping.

Looks good, but I'll wait for the reviews

I received one yesterday from RC4WD, just one week after payment.

I have just had the time to get it out of the "box" (no wooden box, just carton and styrene) and clean the styrene/oil mess

Shipping package issues apart, looks like a nice model for the price.

Although some dimensions are out of scale and it is not a real model (mix of B an D series features) the castings are excellent and equivalent to diecast models quality.

Cab is clearly 1/14,5 scale, and, if you consider that scale, most of the dimensions make it a 460/480 model (50 ton class).

Pictures and more details to follow

Hey bro,
I reckon half of this forum is looking at your profile, hoping to see some review of this new model
I'm also trying to make the decision between this one and The Mother digger.
This one would be just under 4000€ after tax and the mother would be about 25% higher price... so I'm really waiting for a review to make up my mind.

I would buy the mother excavator over this one anyday

'the Mother' machine is of another league than the Eagle/RC4WD...just difficult to compare..And it's 36t vs 70t machine...The 360L is a more handy machine to deal with sizevice, just 235mm width of the undercarriage, well suited for low loaders. 4-5000 € for the 'Mother', wasn't that just a symbolic introduction price...or you can really order one for that price now..? With the 360L, in 'worst case' you need to replace the valve block and pump with Jung/Premacon, so ad a 1000€.

I agree, they are 2 different equipments and hard to compare. For that price, the Mother earth mover already includes Premacon valve block and pressure relief valve.
Not to mention the cylinders are industrial hydraulics made with industrial gaskets and the shaft is chrome treated, not something that was made at home. The pump is also industrial. It's surprisingly very quiet.

How much is the Premacon valve block?
how many channels is the block that is used in the digger, 3 or 4?

Sorry for the waiting time.....the 1:1 scale sandbox took a lot of my time in the past days.

I do not want to compare this "360" with another model, as I do not have any idea of what the others are worse.

I will not add a lot of pictures also, as the model can be seen from all angles on the RC4WD website. If you are interested in a specific detail, just ask, I will try my best to satisfy.

Just facts :

About dimensions, as mentionned above, if you consider the scale is 1/14.5 the "360" is based on a Volvo 460B/480D model, so a 45/50 metric tonnes model.

Undercarriage is 248mm wide and 303mm from center of tumbler to center of idler wheel, which make it exactly fit the dimensions of the variable gauge 480DL chassis in extended position. However, it represents a fixed gauge chassis. This "mistake" apart, the details are excellent.

The upperstructure features a scale "B series" looking cab, with a decent interior.

The one piece, heavy counterweight is also modeled after a B series and looks nice.

Overall, the upperstructure is 231mm wide, which is out of scale whatever the original model considered. 36/50 tonnes machines are just 2990mm wide and this would give around 210mm in 1/14.5 scale

The left hood panel and resulting counterweight clearance radius are the only things clearly inspired from a 360D.

The right panel has louvers, which is pure imagination, and looks particularly weird on the area where you are supposed to find the hydraulic tank of the real machine.

The top panel shows anti-slip material, which is accurately molded.

All the parts are die-cast in zinc or aluminium alloy with a high quality of the details.

The digging equipment features the 7.00 metres standard 480D boom with the 3.35 meters stick. The digging enveloppe of the model looks close to the previous 4200XL, but I did not have the opportunity to put both models aside.

Although "only" 100mm wide, the bucket is really a masterpiece of casting! It's plenty of details (wear plates, reinforcement gussets, etc.) and looks decently close to a real bucket. Now, will the alloy resist to real play? Only time will tell.

As you can see on the two pictures, the guts under the hood are arranged with care, and there is space enough for a big battery (8500 mAh in place). Be careful, the maximum battery dimensions given on the website are absolutely not realistic.


The hydraulics are very interesting. The new system features 2 check valves in the circuit. One is located on top of the main valves and the second is "hidden" in the de-dusting filter on top of the hood. This last one is used to adjust the max pressure by simply rotating the cover (no tool required), and the integrated manometer directly shows the result.
The real positive point is that the pressure in the circuit remains at a low level when no function is activated. To my knowledge, no other model manufacturer offer this advantage.
I haven't made a test "in field" now, but the equipment forces seem to be way enough for serious digging.

Sorry for the long post, but I wanted to tell as much as I could about this model. I hope this helps

Thanks for your info Papy. Have you checked the weight of the machine? It's said that the tracks are of steel now, not the weak aluminium castings as the last version of the 4200. Can you do a magnet test?)

I like your review!
Please let us know how the castings stand to use and abuse.

In regards to dual stage hydraulic system;
- exactly what I have in mind for my project - if I ever get to that stage instead just pulling the trigger on the prebuilt model.

I think that the benefits of such system are in reduced energy wasted while the hydraulic system is "idling"... I'll have to try something similar with my hydraulic parts soon.

Oh, I nearly forgot to address the weight issue.
I know that it is very hard to pull a loaded trailer. 27kg, I bet the trailer has at least 3 to 5 more and that makes really heavy load. I don't fancy trying to tow that on a loose surface. But, isn't that what is fun? Building your tractor truck with large reduction rates, having decent amount of power, building and "cheating" the drivetrain to make it - yeah, that sounds fun to me!
