The WPL C24 and C24-1 is a great truck but once you've added all the metal chassis options and some wheel weights the stock drivetrain can really start to struggle. The stock gearbox can also cause problems with ground clearance and getting caught on rocks. We wanted a way to achieve more power, better crawling control and improved ground clearance, so.....

This kit is designed to allow the installation of the trx4m 370 motor and gearbox assembly, supplied by injora. This also requires new electronics and we recommend the T6 and ESC kit for 1/24 scale crawlers. This is easily installed using the supplied velcro.
Parts required:
Injora TRX4M 370 motor and gearbox https://www.injora.com/products/injora-370-brushed-motor-with-metal-transmission-for-1-18-trx4m

NOTE - you may be able to use a stock trx4m 180 motor and gearbox with the WPL electronics however this has not been tested. We'd love to hear how you get on if you decide to try it!

One more thing....  please ignore the paint job if it's not to your taste but my kid was very happy with their handywork :)

Happy crawling!
