I hope that your rigging comes out to the good. I wouldn't be surprised to find other printings of the same manual would say something different.
Again, good luck

Hi Robert

I will be happy just to get it off the ground I got it in a basket. I found out over the years on the small low powered stuff that wash out can up your cruise at the same power and make the inboard stall first so you would still have good aileron control.
Thanks for the reply

I can agree with that. I has a J-3 with recommended wash out and it did good. With a 65 Cont., I cruises at 85 mph above 10Kft, full throttle and leaned out to less than 3 gph from take off to landing. I used the mixture function on the Stromberg. It was different. You could never shut it down with the mixture, pull it full on and it would just surge. It would get a burst of fuel when the pressure in the carb reach ambient pressure.
Regarding the 24, the part I hate, is it is faster with the wheel fairings off, versus on.
Thanks for the information on the amount is change to the strut length versus degrees of change. It confirms what I was thinking. I figured that being within less than 0.1 degrees was close enough. I guess that the proof in the pudding is when I get the old girl up for the first time, maybe the second or third time. It may take that long before I get over the joy of flying the Fairchild for the first time since June 1973. The photo of 81340, that is in the Club Photo gallery is of the Fairchild the last time she flew. Little did it know at the time, one of the dog ears on the master rod was cracked. It didn't take a dye check to find it. If you look close at the steps, it looks strange. I had transported an Aeronca aileron from Paul Valley OK to KC.
On my rigging method. I used a dry wall "T" square and a plumb line. It worked out that 3/4" on the long scale was equal to 0.1 degrees.
Thanks for the information.

Hi Robert
FYI ½ turn = ¼ degree. I found that out yesterday. I decided to leave my wings flat twist wise. Will get a test flight on it first and then change it if I am not happy with it. I will be happy just to get it off the ground I got it in a basket. I found out over the years on the small low powered stuff that wash out can up your cruise at the same power and make the inboard stall first so you would still have good aileron control.

Personally speaking, washing out only wing doesn't seem right. It sound like worrying about "P Factor" in a J-3. I was told to rig my wings on a 46W24 the same. To the best of my knowledge, mine right wing is less than 0.1 degrees to the positive, of the left. I stopped there thinking that 1/2 turn more would make it more than a fraction of a degree the other way. When and if it flys straight and level hands off, you will hear screams of joy all the way to the east coast.
Oh, my 24 isn't stock. It is sort of Frankenstein-ish. Right wing is civilian, left wing is UC-61, motor is off a later UC-61, rudder & vertical fin..don't know. The only thing that I know is fuselage & data plate are OE.
I hope that your rigging comes out to the good. I wouldn't be surprised to find other printings of the same manual would say something different.
Again, good luck
