Plotter - 3 servos

Thanks Eziosoft for sharing your project. I am trying to put together something very similar where precision is critical. However I am a complete newbie. I'll appreciate if anyone can provide brief feedback on the following:

  1. I plan to use three Hitec HS55 servos for the arms and the pen. Is this a good enough servo for high precision?
  2. Is the Arduino Uno the right chip for this project?
  3. Do you know if there is any code similar to Ezisoft's in C#? I am more familiar with C# and hope to build upon it for further functionality.

Will appreciate your feedback.

Thanks
