We had a discussion on the left roll tendency that my Pulsar XP has. It doesn't track straight-I have to have a slight amount of right pressure on the center stick to keep it tracking straight. Let go and it begins a slight left turn. Kind of a pain when you need to review a sectional, etc.



I usually fly solo, so perhaps the weight on the left seat only is also a factor? 



Are you using a aileron trim tab(s)? Does anyone have a picture of a small trim tab they are using for on their aircraft and perhaps, a source for them? 



I have a small trim tab on the rudder-it's about an inch wide and at a 30-degree angle or so from the rudder tab-Is this the same size I should be looking for?

I have a roll trim system that uses a servo to control the centering point

of a two spring system. Due to the left wing heavy tendency of my plane, the

trim system had to be kept full right. I added an 18" piece of balsa wood

which is designed to be the trailing edge of a model airplane wing. It is

taped to the underside of the right aileron near the outboard end, with the

thinner dimension facing forward. This allows my trim system to remain

fairly centered in its travel. The balsa is on the underside of the aileron

so is not visible unless you bend down and look for it. I am happy with my

"trim tab" which has been in place for more than 7 years (using the original

tape).

I used a simple wedge shaped balsa piece (1/4" x 1") double-side taped to the underside of one aeleron.  Cut length based on correction needed.  Been there 16 years.

FWIW: N9DK does not have aileron trim tabs, just servo trim.  I often fly hands-off for extended periods with only minor rudder inputs every few minutes.  In fact, it makes you lazy and I may look down at my flight plane, phone or sectional for much longer than I really should. I do tweak the trim during the flight to compensate for fuel burn, and she is more stable at certain speeds than others.  ~120mph seems to be a sweet spot for the longest period of time without control input needed.
