Eliminate conduit under baggage floor?

I used clickbonds and snakeskin on my RV7 and it was a very neat tidy install, the clickbonds adhere well and keep everything neat. It still amazes me how a much wire is required to wire a plane. just a thought, same idea as yours but perhaps lighter and a bit easier to install, plus you can snug them down on final wire.

You don't need conduit. My 1955 Cessna 180 doesn't have any and the old wires and the holes they are in (with rubber grommets) are still airworthy.

Another option is to run a line through each cable run and leave it in place. coiled up at either end with enough slack to pull future wires through the areas that are inaccessible. Even if you use conduit, it would be wise to leave a line in place to pull wires through.

I ran my wires down the center tunnel on either side and below the elevator pushrod. I did a full job of wire lacing, then attached them to the sides of the tunnel with cable clamps that have a sticky backed surface to attach.

Being an electrician, I would use conduit. I have 3/4 inch PVC in each wing and the wire is installed with a pull string for future use.

When pulling wire through grommets, there is always the chance of the pulling head will hang up on the grommet furthest from an access hole. Using conduit, you give yourself the ability to pull the wire in quickly with a minimum of damage to the wire. Also, as you pull the wire through grommets, there is a chance of pulling the other wires (drag) in which will cause a sag or sags in the wire increasing the chance that something (aileron bellcrank, for example) to snag the wire, possibly causing control lockup.

Use the grommets away from control pushrods and bellcranks if you must use them.

Take care and fly safe.

Good advice. Sag was one of my concerns but also vibration of the grommets against the wires.

Will use the conduit and pull string. Thanks to everyone.

In order to save some bucks, I bought 1/2" ID corrugated conduit tubing instead of the regular 3/4" Van's sells.
Do you think it is wide enough, or do you think it will get all cramped inside using this diameter?
