Re: Rc4wd 870k wheel loader unboxing and review.
 

Thanks Mike. It sure wasn't like this with the default settings from factory. I was barely able to control it.
JD customs has built a good machine, but the radio settings and some of the mechanical settings like the pressure relief valve were questionable. Once these were massaged, it was much more predictable and controllable. I prefer having all the drive sticks on the right side (similar to how a plane flys) and the bucket and arm left stick.
I will add to this that the pump motor, speed control and servos work much cooler now. You can touch the pump motor with your finger for as long as you want after running it for half an hour. Now I know why they took the rear fan out. Plus it makes room for the Lipo.
Surprisingly the electronics run very efficient. Only the drive esc and motor will get warm if you use it in 2nd gear which is expected and totally normal.

Thanks Brandon. I'm pretty sure if I kept the default settings, parts would start to fail.

Standard grocery bag is just over 17".
Max reach to the bucket pivot point according to rc4wd is 18"
I did some rough dimensions comparing to the dimensions of full size cat 980h (pretty much the same as liugong clg888) and the result is 870k is much closer to 1:12 scale. Not 1:14 as advertised. :cop:

Re: Rc4wd 870k wheel loader unboxing and review.
 

I’m not surprised as when you see the 870K next to other loaders that are 1/14 it’s all together a bigger machine. Gotta love that extra reach though :cool:

I put her in the dirt. I get better operating on the 2nd video. Surprisingly the Lipo lasted approx 35min each and I stopped it at 11.5v Very efficient. Used 5800mah lipo.

Awesome videos Shawn :cool:

Re: Rc4wd 870k wheel loader unboxing and review.
 

Once again your video quality is awesome , are you going to get some decals made up for the 870K ?

Re: Rc4wd 870k wheel loader unboxing and review.
 

Thanks all.
I'm debating on what model to make it. It already has CASE colors so maybe a 1221F?
But just recently i saw someone who made a whole new engine hood and converted to CAT 980. It looked great! Here is a link to the video: https://www.youtube.com/watch?v=EVfm...2V87JesLCevhOg

Re: Rc4wd 870k wheel loader unboxing and review.
 

I agree, the guy did an awesome job converting his loader :cool:

Re: Rc4wd 870k wheel loader unboxing and review.
 

This is your opportunity to have the first Case loader out there.

Re: Rc4wd 870k wheel loader unboxing and review.
 

The 1121G with the grey wheels is a slick looking ride and different then most. Thinking I'm going to make a new engine cover. Eliminate the gray crossover under the hood, fix the air cleaner and ext to the hood and gain much more Batt space.

so i went and got 4 zippy5800 mah lipo battery seems they have different type of connectors than the 870 loader is there a set of adapters from bullet con to the connecters for the zippy batteries

Re: Rc4wd 870k wheel loader unboxing and review.
 

Yes, search evilbay, they have several kinds/styles. Or you can take it to your LHS & have them solder on new ends fir you, or do them yourself

Just installed Beier USM-RC-2 sound/light card. I'm using default settings with a prerecorded liebherr L586.
Haven't fine tuned it yet. I have to reverse the back up beeper noise. The software has a learning curve.

The pump is so loud on the first video. I've seen the 2nd video before. Thanks!
So after messing with mine, I finally decided on this sound. It sounds throatier in person compared to the video.

Adjusted the turbo noise. It was too loud before. Now it sounds better. https://youtu.be/SYTcsaYZOOQ
