Center of lift pointing upwards and downwards, what does it mean?

[Lammet]

So I made a plane and I pointed some wing parts downward and upwards and the CoL pointed a bit backwards, what are the effects?

I guess it just means you have a little extra induced drag. If it points a bit backwards, I'm guessing you rotated a wing part upward so it has a higher alpha. A wing part rotated like that should give you a little extra lift at the cost of speed, though.

How far downward and upward did you angle them? If it's less than 10 degrees you should see extra lift at the cost of lower speed due to drag. If you start angling them more the 10 degrees you may actually see less lift and massive amounts of drag.

 

Usually, when I give my wings Angle of Incidence(AoI), I limit it to +5 degrees for subsonic planes and +3 degrees for super/hypersonic planes. AoI is the angle that your wings differ from your fuselage. When I adjust my AoI in the amounts I specified, oftentimes the CoL indicator will move but not rotate. If your CoL marker has rotated visibly, your AoI might be too high.

It's like 45 degrees backwards

The CoL indicator? The blue bubble with arrow. Just want to be sure, cause that 45° sounds extreme. Can you post some screenshots in the SPH? Though it sounds like you have your wings perpendicular to airflow or close to it. Usually my CoL arrow is no more than 2-3° degrees from vertical. Screenshots would be very helpful.

Well that plane is long gone but was just wondering...
