I was going to keep this under wraps and see what I could find out, but this has stalled in recent times so thought I'd find out other people's experiences.

I was wondering how viable it would be to use Solenoids in place of Pneumatics?

Some preliminary research shows that solenoids can be as powerful as LP systems, work on viable voltages and be an acceptable weights, but sourcing a supplyer is proving tricky.

Has anyone else tried this?
