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 plane’s centre of gravity (CG) is too far forward or the elevator trim is set incorrectly. 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 the battery or add weight to the tail to balance it. Next, verify your elevator trim is neutral before launch; if the elevator is trimmed down, the plane will pitch down immediately. Also, ensure you give the plane a smooth, level toss rather than pushing it downwards. Finally, check your control surfaces for correct direction—if the elevator controls are reversed, it could cause a dive. Adjust these settings step-by-step: balance CG, set trims to neutral, confirm control directions, then practice gentle launches. This approach should stop nose dives and give you smooth, stable flights.
