what's scary is when you are used to low rates and havent really flown much on high rates and then you take off in high rates, forgetting to flip the switch. that just happened to me recently. i was taking off and it did a nice wall, right off. if gave it a little down not knowing what was wrong with it, and it took a nice dive and i recovered pretty quickly, (about 2-3 feet from the ground, right in front of me) got control, and fliped the switch. that was wierd.
