My 68" span sports profile has a difference of approx. 0.5 deg positive incidence between both wing halves. Will this have a noticeable effect on the model's flight performance, and can this difference be trimmed out in flight. Your thoughts please.

Differences in wing incidence between the left and right will lead to unwanted roll. You maybe able to correct with aileron trim but, your trim will change with the speed of the plane.

If you are a precession flyer you will notice it. This is a profile plane so that is not what you are doing with it. You will get a bit of a roll which you can trim out with the ailerons. You are not going to be flying a profile at high speeds so I would just go fly, flip, and torque it. Have fun!
The only problem you might have is the wing with less incidence will stall sooner at slow speeds allowing it to stall to that side. It is only 1/2 a degree and I bet the ailerons flex more then that. You can take the time to fix it but again I would just go fly it!

Just fix it and it will be more enjoyable to fly.

Just thought I would check in to say thanks to all who responded to my question and to advise that I recently flew the model and was pleasantly surprised to find that other than 3 clicks of right aileron and 2 clicks of up elevator the model flew very well and needed no further trim adjustment throughout it's entire speed range and with a wing loading of 23 oz./sq.ft the landings were trainer like.

If it flys well leave it alone.
