It's so nice to know that if I just follow the plans, it's supposed to work! But inquiring minds want to know anyway:

I'm following the 71" Astro Hog plans that I've blown up to 89.75"
My nearly completed 17 1/2 lb model has the Moki 2.1 engine with zero degrees on the datum line.( zero up or down thrust as specified, but I added 1 1/2 - 2 degrees right thrust too) With the datum line level and at 0, I have the stab at an attack of +1 1/2 degrees to it, and the wing at +2 1/2 degrees to the datum line as well. (as specified) If it makes a difference in the whole picture I'm describing to you, I have cut the wing dehydral in half too.
(Think it was 12 degrees dehydral down to 6. I don't remember)

Also: I might be up another 1/2 or 3/4 of a degree higher on the wing too then the plans specify (+3 -3.25 total degrees instead of maybe the called for +2.5 degrees total.) Yep, you do all that fussing during construction, and then you put that laser meter on to find you still got off the mark somehow when fitting the wing to the cradle !!!

Anyway, what effect do these angle of attacks have on a bird? What charachteristics does it cause, versus if it didn't have these incidences? Is an extra +1/2 to +3/4 degree on the wing a biggie?
