Why does my RC plane nose dive on launch and how can I fix it?

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 or the elevator trim is set incorrectly. First, check the CG by balancing the plane at the recommended point, usually around 25-33% of the wing chord from the leading edge. If it’s nose-heavy, shift the battery or add weight to the tail to move the CG back slightly. Next, verify the elevator trim is neutral before launch—if it’s trimmed nose down, the plane will dive immediately. Also, ensure you launch at a moderate angle and apply steady throttle; throwing the plane too hard or nose-down can cause a dive. Finally, inspect the control surfaces for correct movement and no binding. Adjusting these factors step-by-step should eliminate nose dives and give you smooth, controlled launches every time.
