I've been flying my GP 40 Stick for 2 seasons now.
I notice that at the top of my loops and Cuban 8's. That
the plane would roll slightly at the begginning of the down
line.

I was giving the Stick a good cleaning (glow snot) and
found the outer right Aileron hinge (ca) was broke in to.
I'm pretty sure this was the culprit to the sudden change
in flight characteristics.

So it does pay to do maintenance regulary, JMO.

If it took you 2 seasons to notice the hinge problem, I think you are not observant enough. I give all my planes a thorough going over every week and
a preflight check every flight.

No, not 2 seasons, just one Saturday and I knew something had
changed. I was flying on high rates and trying new things.

<font color="#000000"><u>maintenance</u></font> !  You can pay now or pay later.  It is usually less painful, to pay a little attention at least every trip to the field.  Safer too.   

Over a season (or over winter, too) your fuel tank stopper/lines, etc. can become soft or deformed and even loosen up. So you might just pull the fuel system and reassemble with new parts as necessary.

Boy that sounds real nice!!!!!!!!!!!!!!!
