JST Male 2 Pin Connector-10pcs

It sounds like you’re talking about JST (Japan Solderless Terminal) or BEC (Battery Eliminator Circuit) connectors, which are indeed commonly used for small electric planes. These connectors are often used for battery and motor connections due to their small size and reliable performance. While pre-made leads are readily available, crimping terminals onto wires using tools like the Economy or Deluxe Crimping Tool offers customization and flexibility.

It’s crucial to consider the gender of the metal contact when labeling JST connectors, rather than focusing on the plastic housing. This ensures compatibility and proper connection.
