Got some things done in the last couple evenings. the swivel is completed and the hinges for the dump box done as well. got a pretty good idea what I'm gonna do with the rams for the dump also. Here are some pictures.




compare the box size to my rc converted tonka dump truck.

Agreed, lots of articulation. One ADT is, or has been on my to do list for a while. Like watching these trucks meander through the rough stuff. Looking good , keep the progress pics coming.

I need some opinions on dump angle. I have right now with the actuators I have and with good lifting power about 35 deg. think that's enough to clean the box?

For marbles, soy beans or Legos yes, for dirt no.

so I found a chart with the highest angle being 45 for wet clay everything else was less. I played around with different ways of gaining more angle even had more actuators involved but I think I'm gonna break down and order some longer ones. hope to get close to 50 deg which I think will be lots. I'll show some pics of what I came up with before I decided on the longer rams. it gained me 10 more deg of angle.


the 30 mm actuator was sitting horizontal and would push the longer one so it would gain tilt angle. if have to build some sort of a skid pan for it to slide on as the little ram was bending.

Yeah, your chart is quite accurate for scale too, anywhere between 35 - 40 will be fine for rock or dry dirt. If you do load any wet, don't pack it down with the bucket & it should slide out. A good acetone wash & metal-etch primer, keep the box inside as slippery as possible.

From Claus' pic, notice the location of the dump cyls being low & outside of frame? I noticed the gap you have between tires & frame, dual long Actuonix actuators would give you the most lifting power in this location.

You didn't put an elevated tail in your box? yet?

Ya I've seen the rams out side of the box not under. I'm gonna order some longer rams and see how it looks on the outside and how much it would lift. As for the elevated tail I never even thought of that. probably will leave as is for now. maybe could add it on after or build a new box.

Here is a lot more info on the servo:
- https://www.aliexpress.com/item/Free...899809165.html

And a couple of demo videos:
- https://www.youtube.com/watch?v=rPN92jVIs6o
- https://www.youtube.com/watch?v=GwRxrp4nzDA

The servo is supplying 5V on the 5V servo lead and it can power your receiver this way, but if you are powering your receiver from a different source, then disconnect this red lead on the servo cable. Also, it can only supply 20ma 5V, so if you have any other normal RC servo on the same receiver I suggest disconnecting the red servo wire and power the receiver from some other power source.

I'm gonna try it again tonight I will use it to power my servo and see if that'll make a difference. also the link for more info just said it was not avaible anymore.

I have a 3s Lipo powering the servo and no power is feeding the receiver. I noticed on the videos that it has a light one when working this does not.

so I ordered another servo from China think I wired it up wrong and fried it. But it's the same as what I ordered again so I got it mounted up. Also the rams came in and got them mounted. I went with lifting under the box instead of on the sides, it was easier and I tried on the sides it wouldn't give me enough angle of dump before it hit the tires. Now I have **** near 60 deg of dump angle which will work great.

I'm really impressed with your build and your ideas. This has helped me on the ADT I've be planning to build in near future , i'll be watching for sure.

I got the replacement steering servo in from the slow boat. I am amazed at how much power it has WOW. I would not want to get a finger in it while it's turning. works great nice and quiet also. hope to get some time this set off to work on the cab now. I've never worked with styrene and it's a learning curve that's for sure.

I'm SO happy you got the steering servo working. I felt really bad about telling you to get one, and then it didn't work. I'm really relieved now! :-)

Looking forward to more great pics!

ok i have a question about wiring up the drive motors. If I do one side the proper way positive to positive negative to neg. do I need to do the other side the opposite so they turn the same direction? I really think in over thinking this but would like some advice from the more experienced builders on this great site.

Also I started on the body think I might do something to cover the front wheels not sure yet.


Not sure why some of the images aren't working.
