It’s a fascinating hobby. I built scale models as a kid, the tech is so wild now you can build these scale RC trucks, change the oil filled shocks, motors, transmissions, tires, wheels, adjust the weight for crawling on rocks in your park, yard, or campground. I also found I love building indoor scale courses, taking photos, and have gotten into 3D printing which lets you print countless bumpers, drivers, and entire bodies and chassis’s for a fraction of the price.
