Here is a link to a file in Box: https://uofi.box.com/s/ykq9ilqy7cgfljxqkjdcc5hlgyzvyy46

Yes, I do. I am not part of that colab, I just downloaded the instructions because the cube seemed cool. Unfortunately the max size of file I am allowed to put into this reply is 0.1 MB and the instructions are 2.5 MB

It's disappointing that the servo is not proportional.

Well, I may have really killed the box when I tried to run two buggy motors off of it: one was the original Lego buggy and one a Chinese copy (the copy's speed is not quite the same, so the two motors were rigged to run together through a differential). I am trying to suppress that memory --- I feel so stupid.

I have discovered that plugging in a lego buggy motor into the cada battery box is a very bad idea. The box is dead. Speaking of buggy motors, the Chinese are now making copies of buggy motors (the only difference is that there is a cable that ends with a PF standard interface). They are fast and drain batteries like there is no tomorrow. I have gotten two off ebay for about $US 15 each. I wonder if the same or similar motor is in the Mould King L-motors.

Hi, This is my first post on the forum. I have bought CaDA C51041 last December from a seller in Hong Kong by way of ebay for less than US$45 with shipping. It arrived a few weeks later. I was impressed by the complicated design (but I am not much of a technic builder). I had no problems recharging the battery box --- I use the USB cable that it came with that I plug into an old i-phone 4 transformer. The crawler is quite slow when built for climbing. The quality of the structure pieces is good, the panels not as much, as others have already reported. The servo works, but is a bit sloppier than the Lego servo. I then went ahead an ordered C51043W from a different seller on ebay for US $41 with shipping. It arrived in a few weeks. The design is more straightforward --- a buggy with a rear differential and 4 wheel suspension. One of my kids wanted to compare CaDA L motor to Lego's. He suggested we use a trick he learned from one of Sariel's videos --- connecting the two motors by way of a differential. We ran them off the same Lego battery. You could see the differential turning slowly --- CaDA L motor is a bit slower then Lego's. We have not compared their torques. Again, no problem with charging the battery. The charging process itself is fairly slow and the charge lasts about 20 minutes of constant use. But the battery/receiver is compact and has many options for mounting. Overall, I am quite happy with my purchase. I feel that I got what I paid for and maybe a bit more.
