You own my future, no matter how expensive. I wasn't expecting it to be able to wag left and right! That's a giant controller through... but you may have explained that. I don't have audio at the moment. This is amazing though and I wish you'll do the same for all external extremities.

A lot of things are o the cards. Not sure what you mean by the 'controller' If its the servos then I do need some fairly strong servo to overcome some of the resistance to movement. Otherwise it's just a notmal R/C transmitter unit.
