For Scott and everyone else.....

I, too, would be interested in information and ideas on linear actuators
from someone using them on airplanes.   Linear actuators seem to be tough
little rascals.  One used on the Bunton professional lawn mower.  The
actuator is powered with 12V from a typical lawn tractor type battery.
This actuator raises a 200 pound 62" mower deck in about 3-4 seconds.  It
seems there would be a weight savings getting rid of the hydraulics and
pump on the LNC2.  The trick is to figure out how to free fall the gear
with electrical failure.

Can be used for elevator trim motors as well.......
Linear actuators maybe ideal for use as an elevator trim motor because they
are instantly reversible and have a strong push and pull energy.
