Scaleart - assembling an Arocs 8x8 roll on roll off kipper

[Rakthi]

YES! Hydraulics work. Succeeded in getting a charge out of the battery. I put a spare nipple on a piece of hose and screwed it in the pump. Found out that the pump was sucking instead of pumping oil out. So changed the direction of rotation in the transmitter. Had just enough juice to see the mechanism go up. So much for trusting the pre-programmed settings you get with the Commander

So tomorrow have to find out why the other servo isn't functioning. Hopefully just a broken connection.

Now I know why I have stayed away from hydraulics You have a lot more patience than I every thought about having. Even with a degree in electronics, this end of the hobby simply makes me loose my mind. Hope you find all of the problems quickly and easily.

Hi tc1cat, hydraulics are simple! Should have figured it out sooner that the pump is bi-directional, after all they use the same one in the three way kipper where the pump pumps the oil to raise the dumper body and sucks the oil back out to lower it. That's why when you look at the videos the dumper sometimes goes down with little jumps.

Give me hydraulics over electronics any day! ... when they don't work it's either a blockage, a bad valve or bad pump - at least at the simple level employed in these models. You should give it a try. Only thing is that the oil seems to get everywhere ...
