Hi! Rowland
Find the place of smallest movement but not to weaken the control stick
along with your own appraisals mentioned below.

I'm looking at the bottom of the control stick as I assemble the 
various parts and am wondering what is the best practice (in UK) for 
getting the wiring from a switch or switches mounted on the top of 
the stick out of the stick at or near the bottom.

I had a troll through the list archives for various keywords but 
couldn't find anything relevant, despite having a strong remembrance 
of the topic being aired not so long ago.

I want a PTT at last on the P1 stick, but it would be nice to have a 
duplicate trim switch there too. (Yes, I'm thinking about shielding 
them from accidental activation.)

Obviously the electrical cable(s) should exit in a place that 
minimises the chances of (a) fouling up the controls and (b) getting 
chafed and causing shorts or open circuits.

It seems perhaps safest to make a hole in the aft side of the stick 
(CS16) just above CS01. That way a conventional grommet can easily be 
fitted, something that might be harder to do if the hole was lower 
down and passing through the thickness of CS16, CS16B, and CS01.

What have other UK builders done that has met with approval from 
inspectors and (if involved) LAA Engineering?

regards

Rowland
