I built mine with a OS 91 Surpass II on it and needed no extra nose weight. The plane flew like a dream until a servo failure put it in the ground[:@]. I agree with the others here, move the battery and receiver all the way up. Stuff the battery under the tank if you must but avoid dead weight. Are you running a spinner in the engine? If not pick up a nice Aluminum spinner, it adds weight as far forward as possible and looks great too. [8D]
