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 immediately. First, check your plane’s manual for the correct CG position and adjust by moving the battery or adding small weights toward the tail if needed. Next, ensure your control surfaces are correctly set: the elevator should be neutral or slightly up at rest. Also, verify your trims on the transmitter to avoid downward elevator input. During launch, throw the plane level or slightly nose-up with enough speed—too steep a throw can cause a stall and dive. Lastly, check that the motor thrust angle is correct; some planes benefit from a slight up-thrust to counteract nose-down tendencies. By balancing the CG, setting trims properly, and practising smooth, level launches, you’ll prevent nose dives and enjoy stable flights.
