Hydraulic cylinders that are small enough to be used on a scale excavator are hard to come by. So I am going to list off the few places where you can find them.

Hydraulic Cylinders

Manufacture
Product
Website
Clippard Minimatic
3/8" to 7/8" Bore, 1" to 6" Stroke

www.clippard.com

Leimbach
7mm to 16mm Bore, 25mm to 100mm Stroke

Cyval

3/8" to 4" Bore

www.cylval.com/cylinder.htm

This model has a pump and a distribution block thats controlled by mini servos. Leimbach is a small company in Germany that builds r/c hydraulic excavators and they make all of these components. They can be purchased seperatly but are expensive. An alternative to Leimbach hydraulic cylinders are the clippard 9/16 bore hydraulic cylinders. They go for no more than $20.00 each. Thats alot better than $100.00 but the clippards are about 3/4" longer.
