Re: Where to get miniature hydraulics? OR...

I know I posted in the pneumatic forum but I am looking for small hydraulics. If such a thing cannot be found, I do know where I can get small pneumatics.

However, I cannot use pneumatics because without some fancy tricks they are very fast and only two position. I need them to be rather slow and infinitely multiple position (like hydraulics).

If anyone knows if a pneumatic cylinder can be run with hydraulic oil, please let me know. I was afraid it might eat the seals or something.

It is for a steering setup on a 1:6th scale RC truck.

Now, I had another idea. Could I use a standard RC car oil filled shock, fill the holes in the shock piston (or make a piston without holes) and drill and tap a couple holes in the shock body for fittings? Or would the hydraulic oil get past the piston too easily and cause problems? (or would it eat the plastic piston?)
