How to Stop Your RC Plane Nose Diving 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 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, add weight to the tail or shift components rearwards. Next, inspect your elevator trim; it should be neutral or slightly up to prevent the nose from pitching down. Also, ensure your launch technique is smooth and level—avoid pushing the nose down during the throw. Finally, confirm all control surfaces move correctly and that your transmitter settings haven't been altered accidentally. By adjusting the CG, trimming the elevator, and refining your launch, you should see immediate improvement in flight behaviour.
