Update

I thought I'll tell you all on what's going on. First, adapting new drive motors and weapon motor on Rukia. I'm drawing up the drive motors at this time and should be better than the 35w's. The weapon motor has been replace. And the speed of it, is much quicker. (about 1-2 seconds with no load)

Second, I'm gathering parts for my 4-bar flipper, known as, The War Machine Rukia. So far the parts I have are. A 50mm bore 50mm stroke Pneumatic and 20oz paintball bottle even though I ordered a 16oz.

I'm still looking for a suitable valve and something on the thread end of the Pneumatic, to connect the Pneumatic, to the weapon arm's shaft.

For the drive, I have taking an interest on the Graupner Speed 700BB Turbo 12V, I have no idea what there like.

All this Pneumatic set up looks overwhelming but still going to give it a shot.
