'I'm in Europe assemblying my 24W I've just brought over from the US &
have some concern over the flaps.

Is it correct that both flap bell cranks are identical & not mirror
immiges of each other? Because of the series type system with both
cranks identical, it causes the cables to cross each other very
closely in the right wing.

Following both cables, the large flap cable runs from the lower side
of the flap handle, through the right wing to the crank then over to
the left wing. The balance cable runs to the left wing.

If both bell cranks are identical, then it would be normal they criss
one another in the system.

Does anyone have any experience with this?

Thanks,
Steve Whelan'

'Would you like some photos? My wings are in place and uncovered, with the flaps installed.

If my memory serves me correctly, both the large cable (pulls the flaps down) and the small cable (supplies up tension back to the lever) as you have seen are routed through the large pullies that redirect the forces from the wing toward the rear of the cabin. There is two small pullies located just behind the rear hat spar carry-thru, that raise the cable slightly as it passes through the cabin, so as to provide vertical clearance between the cables.

I believe that both bell-cranks are identical and the actuator arms are both pointing toward the same side of the airplane. Don't ask me right now which side that would be. I can take some photos, and they will answer your questions better than trying to explain it all. I will go out to the airplane Friday and take some photos of any area that you are concerned about.

'I assume that you have looked at the drawing that Tom mentioned. I thought that I was correct in saying that both bell-cranks were identical. They are both P/n 42147. I didn't see anything in the drawings that referenced the routing of the tie-cable regarding the cross-over. The pulleys that support and guide the tie-cable are located forward and slightly above the other two pulleys, so the bottom line is that where they cross, it is close, but isn't of any concern.
If that one will bother you, don't look at the elevator trim cables, where they disappears into the horizontal stabilizer.

Thanks Tom, for refreshing my memory.

'Bob,

After somemore research, I verified what you're telling me here. We used some washers to vertically separate the pulleys further & that helped, as they did touch even with proper tension. Another problems we had, was that someone had rebuilt the wings & the wooden ribs on each wing were different from each other & probably not original, as the flap cables rub on several of those. I'm looking for some phanalic material to make spacers & rub blocks at those places.

Thanks for your support!
