Looking for some help. I just got my first plane and was checking the throws and found these measurements:

Right Wing: Up - 7/16" Down - 1/4"
Left Wing: Up - 1/2" Down - 3/8"

1) Are the differences here too much to have the aircraft fly well, and 2) How would I fix this? I tried playing around with the linkages and was able to line the ailerons up with the trims "zeroed" out, but I still see the difference in throws. Any help or suggestions would be greatly appreciated.

What plane is it? Are you using one servo or two?

Unless you are doing precision acrobatics or an already accomplished flyer, you probably won't be able to see much difference if any between what you have now ans a perfect setup. Fly and enjoy. If you must correct it you can modify the length of one of the horn attach points to change the amount of throw.

Thank you guys for the responses. I have the Nexstar and it is currently set up with the single aileron servo. I was hoping that you would say it is not going to make much of a difference

Once I get proficient I plan on putting in the dual aileron servos and adding flaps, maybe I can adjust it more when I do this. I was going to take the aileron servo out and check the aileron arms because one seems a lot stiffer than the other, but it looks like the guy that Ibought the plane from may have stripped the screws holding the servo in, so if the difference is not going to affect me learning on the airplane, I won't mess with it until Iam ready to upgrade it to dual servos. Thanks again for the information.

Yea its no big deal, only means your going to roll quicker to the left than the right but doubt you'll notice it too much.

My Avistar and also my FW190 both use single aileron servos and I made sure that where the individual aileron control wires exit the wing that they were not actually hitting the wing and limiting travel. They BOTH needed some attention but it was well worth it to make sure they operate freely.

You can equalize these by adjusting the clevis's on the torque rods.

With the transmitter turned off, center up the sticks and trims. Then manually, center up the servo arms.

Next, turn on the transmitter to see if the ailerons move. If they do, then the servo arm needs to be centered. You can do this by first turning off the transmitter and receiver then disconnecting the servo arm linkage from the ailerons, then removing the screw from the servo arm, pull it off then turn in the direction that would center it up. Turn on the transmitter THEN the receiver to see if it is actually centered up.

Centering it up means that it is set so that the arms are either perpendicular from the sides of the servo, or if using the angle arms for differential, that the servo arms are set so that they are equal on the right and left side of the servo. If they are, then put the screw back in and tighten it.

Next, connect the linkage to see where the ailerons are. If they are still "canted" on one side more than the other, then adjust the clevis's till they are equal. The bottom of the ailerons should be flat along the bottom of the wing so that one side is not lower or higher than the other, but are level with the bottom of the wing.

After you do this, they should be pretty much equal.

You should correct the screws of the servo to make a solid attachement to the wing pocket; may be using longer screws and some CA.
Try to loose the arm that is stiff by disconnecting the assembly, moving it by hand and dropping some light oil into the guide if needed.
Then, reassembly as CGRetired has explained above.

Have an experienced RC pilot check your model before taking it off.
