Hmmm.  I was thinking of getting an RC airplane magazine today, I'll
look - Thanks!  Those might be dearer than I'd like, well, more research
to do <G>

On those, I'm a little concerned about cooling, those IIRC use a fair
amount of power - am I recalling correctly?

I will ask the SRS folks, they're semi-local.  (Probably a really good
resource for this one <G>)

Other possibilities are pneumatics & hydraulics, those are possibles for
this project.  I'd rather not use those, pneumatics would be better than
hydraulics (Need more force control than position control!)  Lots lower
MTBF though, I'd think.  I want a well over 2000 hour MTBF on this thing
<G>
