Here is a pick of the recommended system (I think). I say this because there is no information available from the factory other than pictures. As it stands with this open type system air bleeds by the cylinders. Currently the 8711 servo strains itself actuating this system as it's set up. I've tried enclosing the open ports on the servo cylinders and it gets even harder to move.

And...one question, not ¡s possible use one only piston for rudder ? using the two nipples, if you place the piston in the midle position you can control the rudder.

You can do this as well?

You can do that - that is the way I have seen pictures of the Skymaster system setup. However, using two cylinders gives you more pressure to operate the system in case you did not get all of the air out - which I think is pretty much impossible to do given that you don't have a way to bleed the system like you do with a full-size hydraulic system. Also, with two cylinders like that, you could put a mix in to move both servos forward a bit when powered up which would pressurize the system to help hold the nose wheel in the commanded position.
