optical remote control question - model rocketry

I'm looking to control the rudder (only) on a model rocket launched glider.
A kids project. (Yeah, sure! <grin>) Low weight is a huge consideration
consideration. I'm wondering if I could use a LASER pointer with a sighting
device (rifle scope?) to transmit a simple control signal to an IR receptor
hanging below the glider (always in ground view). The signal (on, off; or
modulated) would trigger muscle wire (solenoid) to the rudder, left and
right. This way the major weight component would be the battery for the
muscle wire.

One question I have is whether a receptor sensitive to a LASER pointer beam
is an off-the-shelf component?

Otherwise, is this solution off base? I can't find it having been tried in
the model rocketry or RC arena. Or is there a simpler or less expensive
solution I'm missing?

Tks all.

 

Might be more realistic to look into transmitting some type of a
unique carrier signal from base and use an MC within the glider (small
and lightweight) to detect it and control the muscle wire to home in
on the signal. You could easily turn this into a type of dive bomber
or spy plane having it float around the base at high altitude, or
both. Have fun you've got your work cut out for ya.

 

Try it with a simple kids glider, to see if you can keep the laser on
target. I dont think you will somehow.
