for many of us, experimenting is half the fun. You will learn a lot by trying different things. It looks like you have found the problem and might as well learn from it by trying to fix it. Put it in a beater plane (one you won't miss if it crashes) and have fun. Why is everyone so dead set against fixing things? As long as you use due care (not risking anyone else in a crash or something) experiment. That is how you learn. How do you suspect the people who fix things for a living got to where they are today? Not by pitching everything that gets broken. Who knows, you could become tomorrows expert.
