Either way, I think this will solve my problem.

Yes, if they are flush with the wing on the ground, they will be reflexed up in the air, the airplane will act tail heavy in cruise, and you will need forward stick. Adjusting aileron droop is the best way to fine tune a Kolb in trim, just like John said.

Just one more question.
What is best, adjust the ailerons, the flaps, or both?

K Toney/Folks:
I don't think it matters.
One way to get an idea of how much nose down trim you will require through
drooping the ailerons and flaps is fly the airplane at cruise speed, reach
up and start slowly pulling flaps in until you get close to your pitch trim.
Look over at the flap, note and remember about how much it is drooped.

I'll do that.
I think adjusting both might be best to have smoothest airflow over the wings.
