#2 ESB CPU arm : first tests and after ajustments

I'm working now on the CPU arm activation, the CPU arm is maintained vertically into the body behind the left long door.
In the different movies, the CPU arm lifts up and stays horizontally when R2 is connected to another computer or system.

I try to make the same...

here is a video of my fisrt attempts

I wasn't very satisfied with this tests and decided to work more on this system, after two evenings, i think that i've managed to get a good movement.

I've used a Hitec heavy duty super-sized servo (Hitec HS-805MG) with a high torque which is probably too big for this but works and that was my target.
