'My 24W just left Paso Robles for Haywood where it will be containerized
& shipped to Europe.
On the two hour flight, the pilot reported the rigging was slightly
off; ie: ball to the left & if you let go of the stick the plane slowly
gpes into a shallow spiral.
Both the military UC-61 & civilian maintenance are pretty clear on
rigging, but in either manual I saw no way to measure the wash in/out
on the wings.
Any recommendations on this or rigging in general?
Thanks to all,

Re: 24W Rigging
'Steve,
I'm just now finishing a month long re-rigging of my Temco R46. I've
got a couple more test flights to accomplish. I should have some info
for you in a couple days.
The Frize ailerons are touchy and difficult to set,
The wash/in...wash/out... is difficult to see, and set.
When I got my Fairchild it would not fly hands off, not even close.
I've done a lot of tweaking..It's almost there.
I'll get back with you in a couple of days. Congratulations on your
purchase, It's good to know one will be buzzing around..over there

Re: 24W Rigging
'It appears from what I read from the manual that I have is:
Dihedral is 2.5 degrees
Sweepback 0 degrees
Incidence 1 degree (preset at wing attach point)
The only other thing that I see is the Fixed Rudder should be 1 deg. 6" offset to the right.
So it looks like the wing is rigged flat. If the rudder is rigged wrong, the fairing wouldn't fit very well. Well, I wouldn't think so.
If what I remember when I rigged my Cub is true. 1/2 turn in the wrong direction on one strut, could induce a pretty good turn rate. At least there you could adjust one or both struts at a time, and get really close to neutral characteristics.
On the Fairchild it could be tough since you can only adjust the rear struts. The only other option would be to swap side with the struts. You could get lucky and find a good combination, or you could end up wasting your time. A little bird in the back of my head thinks this would be a fruitless exercise.
I think that I would be looking for a 4 ft. carpenters level and use a variable level against that. Check both butt ribs are the same, then work outboard and still looking for the same number.
Damn, I sure can get long winded. Good Luck

Re: 24W Rigging
'Bob,
Thanks for your wisdom. I'll probably stick with the struts on the same side & go form there. I saw the dihedral & incidence comment in the books.
Perhaps aomone withh a perfectly rigged 24 can measeur the washin/out on theirs & send the results.
Cheers!

Re: 24W Rigging
'Bob,
Some planes have their right wing set at a higher angle of incidence then
the left. This is to offset the left turning tendency. Also on some the
crankshaft is not aligned longitudinally with the airframe for the same reason. And
the vertical stab too.
Make sure everyone is on the same page as far as leveling the aircraft for
rigging.

Re: 24W Rigging
'Correct me if I'm wrong here.....
A higher degree of incidence (or angle of attack, or wash in) on the
starboard wing would only exacerbate attempts to correct for US
engine anti-torque, no?
