Newbie here [] !

I have a few questions.

1. The ailerons are tapered on this plane. That is, they're wider (but not thicker) at one end than the other. Does the wide end go towards the fuselage or towards the edge of the wing ? They came seperated from the wing in the box and it appears they'll fit either way. I installed one already (with the wide end towards the fuselage) and it occurred to me I may have done it backwards and wanted to post here before I do the other wing.

2. Assuming it's backwards, how do I remove the improperly installed CA hinge and re-sinstall. I realize I'll have to purhcase new CA hinges. Do I just cut down the middle of the existing hinge and cut a new slot into the wing "through" the existing CA hinge and not worry about removing the improperly installed CA hinge ?

3. Regarding the CA hinges. Which way to they go in ? With the narrow part stuck into the wing or with the wide end stuck into the wing ? There's a slit that is partially cut into the hinge parallel with the "wide" side. The slit is down the middle of the hinge to aid glue absorption I gather. Should that slit be parallel to the wing or doesn't it matter ?

4. Lastly, the wing seems to be symetrical. It looks the same from the top or the bottom. There's an identical "place" on both sides of the wing to install the aileron servo. Does it matter which side ? I know the servo get's mounted on the bottom of the wing. The manual says nothing about how to differentiate the right wing from the left one. I understand "if" the wing had a flat side, that side would be facing down, but this one appears to be identical no matter which way you hold it.

Thanks much for your help.
