The four bar is also a lot stronger as well i have seen some flippers occasionaly break with the amount of force if it is a single lifter however the extra bars give it more strength so it wont break.
SHW Ziggy is doing pretty good with a Nitrogen pneumatics system behind a 4-bar lifter... Selfrights too.
As a side note the US have just produced an excellent SHW HPA flipper using a 4-bar motion by the name of Ziggy its worth checking out...

Are you sure ziggy is a 4bar? It looks like a mortis style lifter, Wereby the back end of the lifter is pulled along in the chassi by supporting rails instead of another bar.
Or is that type of lifter also called a 4bar?
No the front bar is pushed forward by an pneumatic ram the rear bar just follows and defines the angle of lift.

looks good!
No, it looks Great!
I say we should abduct Merlin and switch the flipper to a 4-bar system...hehe

Oi! Hands off! Is Ziggy on CO2 or Nitrogen? as although impressive for a 4 bar system, its no more powerfull than most FP bots over here.
The four bar is also a lot stronger
I personally dont think it is, as theres alot more bits to break or bend.
Saying that tho i did consider making an interchangable one for Merlin, as the ram could stay where it was, and just required an extra set of mounting points..
Ziggy runs on HPA, at its last event it was running at 1000psi which I believe produces 3.2ton of force at the ram but it can run at double that 2000psi. Because of the HPA system it uses a fiber wound scuba tank for gas storage.
