Thanks for the replies,
The ailerons are a little stiff, they don't fall on their own weight, I have give then a good wiggle but I'm not sure it has freed them up much.
I noticed one aileron id not centered on the back of the wing, it sits lower at the outer end. Also when I do move the ailerons it twists them, the covering goes slack and distorted in areas, this happens on both. I did notice the pre cut hing slots were out a bit when assembling, I should have fixed it at the time.
I have also used tape to seal the hing line on both top and bottom, this may be stiffening the joint some also.

Would it be worth cutting the hings and re doing them ?
if so, do I just cut new slots in the same places as the old CA hinges but in a straight line ? or do I need to cut into a new area ?
or am I better using a different hinge system than CA for the replacements.
I have tried to find a new wing, but haven't been able to buy them as a separate item. This would be my preferred solution.

Some thing else I would like to mention, the engine has been mounted off line a little, the back of the prop is off to the right a little from the center line of the fuse, from what I have read this should not cause problems, but I thought I would mention it in case there is some problem I am not aware off.

Another question, could slack in the rudder cause similar problems ?
