@randomusername trim tabs mean you set trim for the speed, and do not constantly adjust attitude via stick. When autopilot is disengaged, trim is manually controlled.
@randomusername nope. It takes a pretty hard pull on the yoke at rotation speed to get the nose off the ground. Then you maintain a 7-10° nose up until you are clear of the runway. Then you transition to level fligt as speed increases. And you use a lot of trim to negate "pitching issue", which is the very reason trim exists.
As previous users have mentioned, the aerofoil settings dictate how much lift is generated by the wing. This can be particularly helpful if you're building a slow aircraft, STOL aircraft or when used strategically it can be used to increase the stability of your build.
.
However, from personal experience with builds, changing the aerofoil to flat bottom (or semi symmetric from symmetric) will cause a small decrease in your overall maximum speed. It's not a huge speed difference, but if you're prioritising a build for maximum speed (supersonic fighter aircraft, etc) it's worth bearing in mind.
.
Pitching issues can arise from changing the aerofoil type to one that produces more lift. Especially if you're not used to trimming your build out with the different aerofoils. For example, if you add an aerofoil to your horizontal stabiliser (on the tail), your tail will produce more lift, causing the nose to pitch/rotate downward. Likewise, adding a lift generating aerofoil to canards will cause it to pitch upward (as more lift is being produced at the nose end of the aircraft).
@randomusername what pitching issue? If you are referring to different lift at different speeds, that's how aerodynamics work. Symmetric wings don't create any lift at any speed unless they have some AoA, which is why you don't get different lift at different speeds. They are only good for stabilizers.

thanks a lot!,@jamesPLANESii @ThePrototype
Make a plane and make one side have flat bottom wings and the other side have symmetric wings.
Flat bottom produces the most lift, use Symmetric for speed, and Semi-Symmetric is like a hybrid
Hmmm, thank you,@randomusername
