Komatsu PC700 Excavator unboxing and review

[bigpipespete]

I see now what you meant about the original being a bit too square. Once you get that painted and the exhaust on, it will look true to scale.

Great customer service right there! Keep us posted how the new hood come’s out. Love your excavator

Shawn, great pictures of the equipment and show area. Do you have any other pictures of the trailer and the mining truck?

What is the max load on that trailer? And, how did the mining truck perform?

Thank you for sharing the pictures of the show.

Jim

I picked up the air compressor and paint gun from my parents house yesterday. I'll have to practice on something first as this will be my first time using a paint gun.

I have other pictures of the giant dump truck and video. PM me your email address and I'll send some out. The truck definanatly has a wow factor. But I can't speak for its performance or drivetrain. We did convince an adult female to sit in the back and it drove around with no problems. But there is a YouTube video of this guy who's had some serious issues with breaking gears in the transmission. You might want to look there and ask him.

Shawn, I sent you a pm for the pictures and video of this show.

Did you have the link to the YouTube for the video of the Mining truck?

Thank you,

Jim

That's a cool looking truck.

Some things to try for eating gearmotors
Is there a dragbrake on the esc? Set it off or low
Does your tx have exponential? Change throttle curves to softer around the deadband
Punch control? Set it softer
Brakes? Set off or really low

No issues with a King Hauler pulling a 91 pound excavator?

I don't think so. Maybe Riley can fill in since it was his KH.
Here is a video i just uploaded. https://youtu.be/tDipd1S7nmU

I’ve seen a king hauler pull 160lbs on a Rc4wd lowboy without issue. You just need a PMD 4:1 reducer, metal fifth wheel plate, and strong/stiffer rear suspension. Oh ya and hard foam tire inserts

It looks to me, like the speed controller ramps up too fast. If it has a brake function, turn it off. Or a more programmable radio?
Cheers, Neil.

Hi all,

It's been a while since I posted on this forum, I have been away from RC construction machine for a few years now.
I'd like to get back on track and I really like this model, the 70Tons excavator is my favorite target and the price looks like it's a great value.

Im more interested by a reliable machine with lots of diggin power than cosmetics.

I've contacted Paolo, which seems like a very professional guy with amazing craftmanship, but I'd like to hear back from an actual user of this model.
there isnt much videos on the internet and very few threads in german forums AFAIK, so it's difficult for me to get an idea of this model reliability.

So Shawn, seeing that you've been using this model for a few months now I'd like to get feedback from you if you dont mind, could be in MP if you prefer.

Would you recommend this model ? any hint would be appreciated really.
Thanks,

Dimitri.

Hi dimitri. Thanks to apreciate my work. I work a lot for make this model perfect. We work for the detail and performance. We fix some little problem with some professional thing. We make our gearbox with full metal gears and now we are around at 200kgcm force. Now we have massive torque and power. We are on the way to send another model to usa. Our facebook page have a lot of pictures and video. In any case if you need to see something in particular please let me know and contact me. Thanks and follow us. Paolo

Considering the fact that it uses Premacon's pressure relief valve and valves, the reliability would be the same with the Germans for that portion.

The hydraulic oil pump and the cylinders are again from major manufacturers that have been proven in other industrial applications. I can confidently say not a single drop of oil from any of these components. The hydraulic system is robust and works flawlessly. The oil stays very cool thanks to a radiator and fan.
My only concern, it does not have an oil filter. I have brought this up to Paolo and he has assured me that it is not of concern as one can easily change hydraulic fluid since the tank is visible and inspection of oil is a breeze. It is marked how much to fill "min and max." Uses Mobil DTE 24 which is sold in 1 gallon instead of 5 gallons.
The electric motor and esc for the pump is from hobbyking and is readily available and inexpensive. So I'm not worried about that.

I haven't had any issues with my gearbox for the tracks but looks like Paolo has updated the gearbox with all metal gears and is much more powerful than the one i have in mine. Mine feels plenty strong so I can't imagine or comment on the newer one.

The servos are hitec and works well with the Premacon valves. There are 2 electric fans that kick on when the set temp hits above it. The temp probe is located on the pump.

The quality and craftsmanship of the metal frame and paint is perfect. I don't know any other manufacturers that uses ball bearings at the pivots for the dipper arms.

All wires are tucked away and makes the inside look clean. This takes time to do and I can certainly appreciate that.

The lack of details gives the owner a chance to finish off the pc700 with custom details. It gives a little something to do on your part.

I would recommend it but beware of the weight (90lbs). For the price and performance, none of the others come near it.

Thanks Shawn for the detailed review, this is exactly what I was looking for.
I can see the weight being tricky to handle, but at the same time it should add some diggin and operating power, so that's fine for me.

Im definitly sold on this one
Bring some videos while I save my money !
