Thank you for the replies sent. Just one further question...if you cut the tunnel through the foam, I take it the idea is to feed all of the wiring and the plug connections through this. I have just measured the extension connectors I have for my Futaba set which are exactly 3/8in across so would be a tight fit. The other potential problem might be then, if and when you had to remove the servo, pulling this lead out with its connector plugs (with a string attached) could lead to its dragging in the foam tunnel and consequently ripping into the foam as you pulled it:Is that a potential problem here? Many Thanks.
