Why is my RC plane nosediving right after launch?

Question: Why does my RC plane nose dive on launch?

Answer: A nose dive on launch is usually caused by incorrect trim, improper centre of gravity (CG), or launch technique. First, check the CG: it should be slightly forward of the wing’s quarter chord point. If it’s too far back, the plane will pitch down uncontrollably. Next, verify your elevator trim is set so the nose is slightly raised when the controls are neutral. Before launching, make sure the throttle is at a moderate level; full throttle can cause rapid dives if the plane isn’t trimmed correctly. When you launch, give a smooth, level toss with a slight upward angle rather than throwing it sharply downward or too hard. Finally, inspect your control surfaces for damage or looseness, and ensure your transmitter settings match your plane’s setup. Adjusting CG and trim, practising gentle launches, and double-checking controls usually solve nosedive issues effectively.
