Frequently Asked Questions

Q: Does this 370 motor 2-speed gearbox fit all WPL 1/16 RC cars?

A: This gearbox is compatible with most WPL and Mang Niu (MN) 1/16 scale RC vehicles, including WPL B14, B16, B24, C14, C24, and MN90, MN91, MN96, MN99, MN45 series. Always verify your specific model against the compatibility list above before purchasing.

Q: Can I still use my original WPL remote controller with this 2-speed gearbox?

A: No — the 2-speed shift function requires a 3-channel remote controller. The standard 2-channel remote that ships with most WPL RC cars does not support gear shifting. You will need to upgrade to a compatible 3-channel transmitter to use both speed modes.

Q: What is the difference between the metal gear and nylon gear options?

A: The stock gearbox comes with nylon gears, which are lightweight and quiet. The optional metal gears are made from blackened, hardened steel, offering greater durability and longer service life — ideal for frequent off-road use or harder driving conditions. Installation is identical for both gear types.

Q: Is the transmission shaft included in all configurations?

A: No — the transmission shaft is only included in the "Gearbox + Metal Gear + Transmission Shaft" configuration. If you only need the gearbox or gearbox with metal gears, select the appropriate option at checkout.
