Some planes have very bad high speed elevator authority.For example you may have trouble getting out of a dive in time.To evade this you trim elevators to positive G to get out faster.

Also some planes need trimming at high speed to ensure a stable gun platform.

elevator trim: CTRL+up/down arrow
aileron trim: CTRL+ left/right arrow.

Just as in RL you can fly without ever trimming...of course you can probably argue that a person can get everywhere they need to go by hopping on one foot http://forums.ubi.com/images/smilies/16x16_smiley-very-happy.gif

I trim constantly and along every axis that has trim available so that the inclinometer ball stays centered when the stick and pedals are centered.

Basically if your plane is well trimmed, it will not roll, climb, dive, or yaw on its own when you let go of the controls. This is beneficial to your gunnery as well as your speed (a trimmed aircraft can fly faster than an untrimmed one).

Trimming is really important. Try flying the Tempest without any trim, especially at high speed and see how you sideslip unwittingly. Sideslipping is a way to shed speed prior to landing. Not great for a plane being fast. You'll also notice on all planes that if you don't trim your plane will constantly pull up and in some cases push the nose down at high speed (Tempest).

In real life trim was needed for both keeping teh plane in the desired direction but also to prevent the pilot from becoming tired from just flying the plane.

I trim so much. I use the Y-axis on my FS-PRO as an elevator trim axis along with my combat stick for regular elevator movement.

If you're side slipping because you haven't trimmed the rudder you will find it harder to shoot straight.

Could you please clarify that. I do not know what the FS-PRO is, but I assume that it is a two piece combat sytem like my Saitek X52 Flight Sytem having a throttle and a joystick. I'm new to flight simulators and, I'd like you to answer this, I am not sure what is the difference between a command for rudder, aileron, and elevator and their trim commands.

I trim every two weeks unless I have a date with a lady who does not like facial hair.

I use 2 controllers and a track ball for flying. A combat stick and a flight stick pro. The CS is my main controller and my FS-PRO I use for rudder and elevator trim plus other commands.
