Spool Valve









Everything will be cut out of 3mm Alluminum, the spool valve will be machined by a prototyping company

A Jung pump would be a good choice. I have one in my excavator and it puts out 30 bars. Ed

Great engineering and design!

Here´s the link for the pump:

Hi, its going to have wheels?

1.rc4wd do a pump for 129$ or you can get a jung from germany i emailed them in feb and they quoted 74euro + tax and shipping for 0.30cc pump so can get it delivered for just under £100 i think. as for a tank i was going to use a spare tank i have from a nitro heli, not sure if it will work though

2. not really sure

3. pass

4. im using valves from fumotec, check here to see how they mount second post on page

5. currently have a futaba 8fg bought as 8 channel but can be 14channel by a free software download, you can also try specktrum/airtronics/robbe all good radios

6. not sure if it still happens but there used to be a meet once a month in yate or somewhere near there.

hope this helps a little

Nice drawings so far, I love watching scratch builds and I'll be watching this one. Just curious, why 8 hydraulic circuits? I counted the usual ones on an excavator and you seem to have a surplus, so what are they for?

There is a program where you can calculate all the forces, google for it, I will give the link later when I get home. It was payware though.

Since here you can ask questions related to hydr I would like to know what should be the tolerances when making valves and cylinders?
