Motor vibration is the most likely cause of flatter with large gas engines. Adding extra weight to moving tabs with the hope to balance it, can actually make it lot worse, starting point try to fix it, is perfectly balanced prop and fine tune the engine run to minimize it. Unfortunately lot of these ARF balsa build models are very porly put together by cheap labor, with all the internal joints falling apart creating even more vibes.
Convert to E-power, another simple option.
