Hello Cessna owners !

I want to add PTT-Switches to the controls of a 1977 172N.
Since the control horns are not hollow i don`t know how.

Any suggestions ?

my friend's cessna 150A has the same problem.
I made up aluminuim clamp blocks that mount on the control tube hard
up against the front of the yolk. the side of the clamp block has a
recess that the switch is mounted in. switch sits up just proud of the
clamp block. press your finger down on the top of it to talk.
cable is a curly tail down to the panel under the control mount.
it doesnt limit the control movement.
has been in use about 4 years now without mishap.
friend and his LAME love it.
