Whatever you do, don't take it to the local park to "try it out" before you go to the field for your

first lesson. No matter how straight the control surfaces look and how careful you are setting

things up, a new airplane will not fly straight until it's trimmed out. It will bank, turn, dive or

climb, and usually more than one of those. It can be a handful for an experienced RC pilot to

keep a really bad one in the air until you get the trim set so it'll fly straight with the sticks at rest.

For someone's very first flight? Forget it.

Do you adjust the trim while it's in the air or do you have to bring

it back down for each adjustment?

You do it with trim tabs (small sliders on the transmitter beside the joysticks) while in the air on it's maiden flight. If things are way out, you can re-adjust the linkage when back on the ground to get your trim tabs back close to center, but if it's that far out something else is wrong (warped wing, CG, etc.).
