pump flow for cylinder size

[skippy]

im scratch building a hoe that will hopefully resemble approximately a 390 size in 1/14..i work with hydraulics on a daily but im just not all to sure about the requirements for such small stuff...basically the pump is a premacon 900ml per min with relief valve, and im planning on using 7/8 cylinders from clippard, what i want to know is will the pump work for this size of cylinder or should i go a touch smaller, the goal is to have as much power as i can but still remain fairly quick. any help is much appreciated
