First you need an Incidence meter. Measure the current incidence, should be zero on both wings.
I simply elongated both dowel pin holes (per wing panel) with a rat tail file until I acheived 0.5 deg+. Once I had the correct incidence I bonded some 1/16 lite ply doughnuts around the dowel pins to fix the position. Since the wing no longer slides into the 1/16'' cutout in the fuse, I elongated the 4mm hole in the wing hold down stub. That's it. It took about an hour to do, no biggie.
After reading Bryan Herbert's thoughts on trimming a pattern plane, I think getting incidence and the CG right for your type of flying is very important.
If you follow his triangulation trimming technique, yes. However this is no law or absolute truth, there are more ways to trim an aircraft and there is simply not one 'guaranteed correct method', a lot of it depends on personal preferences.
For instance, you created an incidence wheres Sebart chose not to. Sebart probably flies 'zero gravity', in which case you trim an aircraft in such a way that it DOES NOT fly level without stickinput. If you level it out and release the sticks, it wil slowly lose altitude. The idea here is that you trim it in such a way that the behaviour, without further stickinput, is exactly the same level as inverted.
I have a contest coming up this weekend so I'm not going to change anything, but agree with you, one of the things I have said ever since I got this plane, was that, to my personal preference, it should have a slight incidence, though instinctively I would say .5 is a lot. I would give it like 0.25 or something in that neighbourhood.
Anyone who's going to do this, remember that it's relative and that this plane is a woodbuilt ARF, so it might differ from plane to plane. On a single plane you can even get different readings at different temperatures.
The downside to having a forward CG as Brian Herbert advertises, is that your airspeed will go up, both in regular flight as on landings. Since this is not a 2m bird, you want to fly somewhat closer and smaller, and so a high airspeed might not be what you really want.
