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 the plane’s centre of gravity (CG) is too far forward, causing it to pitch down. 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 too nose-heavy, shift batteries or add small weights towards the tail to balance it. Next, verify your control surfaces—ensure the elevator is neutral or slightly up on launch. Also, check your launch technique: throw the plane gently and level, not pointed down. Finally, confirm the plane’s trim settings in the transmitter are neutral. If your plane still noses down, try increasing elevator throw slightly for better pitch control. Taking these steps should help your plane launch smoothly and maintain steady flight.
