Lots of good ideas - Pager motors with a rack attached may be "the" thing I need, the control electronics could be completely remotely run (I'm going to keep looking and thinking ) Cheap is good, servos would be great (don't need exact positioning so no encoders etc. needed) - some servos are too large for part of this, some might be just right for part of the deal though. I think I need to start playing with "popsicle stick and hot glue" mockups some time and see how it goes Mark Peter L. Peres wrote: > Look for RC servos designed for rocket gliders.
