Before going further, note that I understand that plans always trump the photo guide.  What do you do when even the plans are unclear?  I go the the list or call ZAC.



To eliminate my confusion on the size and orientation of the hole (or slotted hole??) on the inboard flap rib (6W1-1), not to mention the orientation confusion between plans and the photo guide, I indeed called ZAC today.  



Roger said that actually all that was needed was a 1/4" hole in the rib and control plate, but exact placement was the issue for some builders.  His recommendation was to wait until final placement to drill the rib and install the plate.  That's now my plan.



For what it's worth.

Hi Larry,



Thanks for posting the information on flap control.



I am just getting ready to install the flap control motor and 

associated stuff in the fuselage.  My take on your report is that the 

actual need for a slot as opposed to a simple hole in the flap rib 

depends on how closely the flap control torque tube is located 

compared to the piano hinge on the flap itself.  The further the 

location of the torque tube from the hinge in vertical space, the 

more you need a slot versus a hole in the flap rib.



It seems that the slot doesn't do any harm compared to the simple 

hole.  It allows variation in the location of the torque tube in the 

fuselage.  This is good since the torque tube is located before the 

wing is mounted on the fuselage.  Also, the actual flap position on 

the wing is delayed until final assembly according to the instructions.



I suppose all this works itself out as you reach final assembly.



Best regards,



Paul

Paul,

  

 You are probably correct.  As one who is quite a few steps behind you, I don't have the hands-on experience to comment.  Just thought the list would like to hear the latest from Mexico, MO.

The most important aspect would be to get both  flaps set at the same angle and that there is no binding as the flaps are  deployed.  If you have any variation from side to side then the actual hole  in the drive plate and rib will be slightly different.

 The distance between the flap drive pin and the  flap hinge pin may vary during deployment and thus the need for a slotted  hole to avoid bending the rib.  Wait until the wings are mounted and do a  few cyclings of the drive pins for the actual measurements with the  flaps inserted close to the final position you will be able to visualize where  the hole (slot) needs to go.

Install the flaps for resale, then don't wear them out.



I've landed at Vaughan more than once, no flaps,

(http://www.airnav.com/airport/WN13)

without consequences and turned around about halfway down the field.

Last time, my passenger, a first time 601XL passenger said, 'if you

didn't use flaps now, when would you.' I try to land on the numbers

at BFI, it helps.



Keep in mind, the Zodiac is a light plane, mine is 715 pounds empty.

Flaps in crosswinds weathervane the plane into the gusts.



But, then what the f*%& do I know. Yeah, I had a bad day.........

I should go fly.

P.S. The above advice does not apply if your airstrip is < 1800 ft.

     I don't have experience with that scenario.
