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.
