I used clear packaging tape to cover two of the three hinge gaps on the lower 
side of my ailerons.  I didn't cove the hinges behind the spades.  Wow, what 
a difference in roll characteristics.  Since my test flight was done 15 
minutes from a legit practice area, I couldn't do full rolls but what I could 
do really amazed me.  

Prior to this change, I found my ailerons to be non-linear.  There is no 
centering, thus, no break-out force (or very little) and as the stick goes to 
about 2/3 travel, the stick force seems to get lighter.  I wouldn't say the 
ailerons are "snatchy" but the feel close to that.

Now, with the gap seals on, they get "snatchy-like" earlier and they seem 
much more effective.

Since I'm not an engineer type, you'll have to forgive the layman's terms but 
I'm hoping someone will have had a similar experience and be able to provide 
some input as to whether this is normal or not.
