RC truck that's kid-friendly requires special consideration. I got one that utilizes a brushed electric motor, which does it just right for us. We don't need gas or nitro, because we're not really planning on competing. Brushed electric motors are fast enough for us, and the model we got also has a "training" mode that slightly slows it down so we stay out of trouble. Moreover, we have the option to upgrade to a brushless motor if we decide we want to take it to the next level.
