Yesterday I saw an automobile power antenna used in an application-non airplane-to move a fairly heavy object up and down vertically.  It used two microswitches to control exact distance movement.  It, of course, is 12 volts.

 

Possible Lancair uses?  I can think of several.  Use it to open or close the tail vent in a LIV in the winter (I use a plastic slide valve from Menard's wood shop vacuum with a push pull wire now). 

 

Use two tandemly and conjointly to open front gear doors on a LIV.  This use might be tricky, but it might be doable.

 

Use one or two to operate speed brakes.

 

Use it to drop down landing lights from a hinged compartment.

 

Of course, modifications to beef up the push rod may be in order, especially in critical area use. 

 

Since the unit was already installed in some equipment, I had to estimate the weight.  I guessed it to be about 14 oz.
