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 the plane’s centre of gravity (CG) is too far forward or the control surfaces are misaligned. First, check the CG by balancing the plane at the recommended point, typically around 25-33% of the wing chord from the leading edge. If it’s nose-heavy, move the battery or add weight to the tail. Second, inspect the elevator trim and control throws; ensure the elevator is neutral at rest and moves correctly when you pull the stick. Third, verify that the launch technique isn’t too aggressive—launch gently into the wind with a smooth, level toss. Lastly, check the wing incidence angle; if it’s too low or negative, the plane won’t generate enough lift initially. Adjustments to these factors should stop the nose dive and give you a smooth launch. Always perform a range and control check before flying to catch issues early.
