What's the difference between hobby-grade and toy-grade off-road RC trucks?

Hobby-grade trucks like the Traxxas and Axial models in this list use replaceable parts, upgradeable electronics, and standardized batteries, so they can be repaired and tuned for years. Lower-cost ready-to-run trucks are easier on the wallet and fine for casual backyard use, but parts support and long-term durability are typically more limited based on verified-purchase feedback.
