Yes that too ;-)

Massive speed is an issue, and if you fail to flip something, the ram can get fairly upset when it fires up into its end stop and some scary speed. You can stick rubber and all sorts in there but it still will get fairly upset. Some calcs showed that my ram would fill in something around the 0.01 seconds mark. So you can imagine it slams open with quite a bang. but again sensible, well thought out designs are the key and you shouldnt have a problem if you keep that in mind.
