Thanks, seeing as I've gone for a hp flipper I wanted it to be a little bit different.

I'd be interested to hear more theories, my thought was the opposite of yours Max- the ram at the back will give more speed at the cost of max force at the tip. Whereas ram at the front will mean it goes up slower but will have more force.

Based on what-I-reckon and the fact I can move it easily enough if I'm completely wrong, and the fact that watch ing the piston go off there's no lack of speed, I went for less speed more force.

But like I say, I could well have missed something myself so suggestions welcome
