Why Does My RC Plane Nose Dive on Launch?

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 as soon as it leaves your hand. First, check the CG location recommended in your plane’s manual and adjust the battery or add small weights towards the tail if needed. Second, ensure your control surfaces are correctly set: the elevator should be neutral or slightly up at rest. Third, check your launch technique—throw the plane level or slightly nose-up with a smooth, moderate force. Avoid throwing it too hard or angled sharply downwards. Finally, verify the trims on your transmitter; elevator trim might need a slight upward adjustment to prevent diving. By balancing the plane properly and refining your launch, you’ll get a smooth, level climb instead of a nose dive.
