I am not sure about the particular plane you are flying but I tried and tried and tried to get a hobbico sky runner to fly and it absolutely would not fly from a hand launch. I am a pretty good pilot and I don't think it is possible for the sky runner to fly. Maybe that is why Tower hobbies discontinued it. If you get frustrated don't give up. You may want to try a Firebird they seem to fly very well and are about a hundred bucks.
