Newbie here looking for help with. I bought 2 new WPL C24’s for my 5 and 7 year old boys for Christmas and they have fallen in love with scale RC crawlers. They are borderline obsessed with it now and have reached the limits of the WPL in its stock configuration. I bought these as a stepping stone to see if they would like it and show interest before buying them a nicer scale setup. I have searched a lot and read up on upgrades but I’m just as much a newbie at this as they are. Could anyone please point me in the direction of a good complete upgrade kit? Or if a complete kit is not available some parts or part numbers to upgrade the motor and gear sets as well as suspension. There’s so much info out there and me being new to it as well I’m totally lost. Thanks in advance!!
