Hi being a newbie myself but never had any problem taking off...be sure your rudder works for minor corrections. Here the best way as i see it.
Ask somebodoy to hold the plane and maximise the throttle in fact i can do this without anybodies help by holding the plane betn my feet . Anyway imp thing is to take off in the wind and land similarly. once your palne moves you can increase the elevator max till it lifts off and then ease the elevator back for a steady climb.. or as most experinced modellers turn the plane into the wind so that it climbs best.

The take off is eay... Landings are critical
