Mika, congrat's so far.I am an advocate of finding an instructor. However, do what you must. The bal. of your plane is the most critical thing to concern yourself with, when starting out. A plane can't be trimmed when out of balance. After you build it as light as possible, then move your batt's and receiver forward until you get the proper balance. Also, remember altitude is your friend. Try and get it one or two mistakes high then let go of the sticks and trim for straight and level flight. Good luck and keep us posted on your progress please PS ALTITUDE = FRIEND/ GRAVITY & WIND= ENEMY
