Slight taps may be all that's needed, but don't tap the sticks, move them very slowly and very gently.

I agree with researching as much as you can. Do a Search for first flights, or as has been mentioned, landing techniques. Read some of the engine break in threads (again if you already have), but don't overload yourself! Your first day will be pretty nerve wracking, so don't "cram" the night before. Get a good nights sleep so you'll have a clear head.

Forget the plans or instruction manuals, they won't be needed. DO bring two or three extra props, one extra glow plug, a full gallon of fuel, plenty of rubber bands (if your wing uses them).

The peaches is a great idea, but also bring WATER, SUNGLASSES and a HAT! There's not much worse than trying to fly while squinting through watery eyes. You will want the water before and after that first flight, because your mouth will get very dry!

And charge all your batteries OVERNIGHT the night before you're going to the field!!

Good luck, you'll do fine.
