Question: Why does my RC plane nose dive on launch?
Answer: A nose dive on launch usually means your RC plane’s centre of gravity (CG) is too far forward, causing it to pitch down when you throw it. First, check the CG by balancing the plane at the recommended point, often around 25-33% of the wing chord from the leading edge. If it’s nose-heavy, move the battery or add small weights towards the tail to shift the balance back. Next, ensure your elevator trim is set correctly—slightly nose-up trim can help during launch. Also, check the control throws; too much down elevator can cause a dive. When launching, throw the plane gently with a slight upward angle to give it lift rather than a hard, level toss. Finally, confirm your motor thrust line isn’t angled downwards, which can push the nose down. Adjust these factors step-by-step, and your plane should fly smoothly without nosedives.
