Don't be afraid to ground launch the plane for your first flight. Its actually easier to control the plane if you maintain your hands on the controls right from the start, rather than tossing the plane and then scrambling to get your hand to the controls before the plane crashes.

If you decide to ground launch, be aware that the plane probably won't track straight, but will turn one way or the other. As long as it isn't heading for some obstacle, let it go its chosen direction. Resist trying to steer it while its still on the ground, because you probably won't have the controls back to neutral once it lifts off, causing the plane to bank, stall and crash. Once the plane leaves the ground, push slightly forward on the stick to reduce the rate of climb. You want the plane to fly nearly level to gain some speed, then slowly climb. Try not to make any turns until at least 50 ft. above ground, and then only small increments, always returning to straight flight for a distance to let the plane stabilize. Your normal flying altitude should be 200-300ft. When you move the control stick to either climb, descend or turn, try not to move the stick more than 1/4 of its throw. Once you rech your normal altitude, cut the throttle to 60% and then adjust to find the right speed to keep the plane flying level.
