I bought Van's conduit, but now I am rethinking this.  Any real  

reason to prefer the conduit to using bushings?  The latter requires  

only enlarging existing holes while the conduit requires new 3/4"  

holes in each rib.



Then again, since I am doing navs/strobes and wingtip landing lights  

(all Creative Air) as well as a NAV antenna in one tip and COM in the  

other (that's COM2 with 1 under the belly), maybe I'll need BOTH.   

That is, two runs.  Will I?



About the wing stand that Van's has on the plans: certainly this is  

not needed for QB wings.  I am wondering what is the best way to work  

on the wings in general: leave them in the cradle (the Checkoway  

style cradle I built), table-top, sawhorses.  I am out of town and  

cannot look at the manual - have these thoughts going through my  

head, as I'll be starting on the wings next week.

Paul:



It is really a no-brainer ... Go with the CONDUIT.

How are you going to fish the wires through the bushings?

You must have very long,very skinny arms. 

No problems with hanging wires.

No problems with chaffing.

No problems running a second or third pair of wires for wing-tip mounted 

antenna or landing lights or Nav lights or Strobes.

OR DOING ANY TYPE OF ELECTRICAL REPAIR

It's easier to pull wires as opposed to pushing them whether it's bushings

or conduit. Run a heavy string through whatever you use when you are

building. Later, use the same string to pull in wires when you need them.

(Pull in a new string also. You never know if a new wire will be needed.)

About 15 years ago, I asked Van at the Merced fly-in the same question.  Van 

told me that the conduit was too heavy for him.



I have snap bushings in the ribs along the spar.  I have the NAV antenna 

coax in one set.  (forget it if was the TOP or bottom of the wing.) The 

other set of holes I ran the power wires for the landing lights, strobe 

power supply (one in each wingtip) and nav lights.

 Wow, I knew Van was weight conscious but how heavy is a piece of thin wall plastic tubing?  The 3/4" is a bit large, all you need is 1/2" or what ever would fit into the existing holes and I would guess the weight for both wings would be just about 2 Lbs.

  

 Then again, 15 years ago is a long time back.  Back then Van was a purest and did not have the QB Kits.
