Best practice is to secure them using solder, epoxy, or Loctite . Unlike press-on gears (which risk damaging motors or require special tools to remove), these only need a bit of heat to install or remove. Just like real race cars , soldered gears are always more reliable. 😉 🚚 Shipping Ships next business day . Shipping is charged at cost based on destination and weight.
