New Memebr needs help: I keep crashing
Look up a local club and see if anyone will help. It is almost impossible for someone to fly an RC plane succesfully without help. Even somenone that flies full scale planes will usually crash if he tries to fly a model. I've witnessed it twice. It is called full scale pilot syndrome. (They will not ask for help and think they can do it, nothing against pilots, just a fact)
From what you have said it sounds like you are stalling the plane after launching it. I have seen a lot of people buy the cheaper RC planes that are marketed to beginners that have never flown before. The instructions "tell" you how to fly it. The crash and crash until they give up. Flying need to be learned hands on.
Get some help and you will be able to learn how to fly and the frustation will go away.
---For the record, I bought an RC plane and tried to fly it. I flew it right into my neighbor's house that was under contruction. It went through the roof trusses and broke into a billion pieces. I realized I was in over my head. The plane was a simple rudder and elevator plane and it lasted about 10 seconds. Luckily my Neighbor had a nephew that taught me how to fly (10 years ago). From personal experience I know what you are going through and know that your best chance for success is to get some help.
