Abstract

A model vehicle comprising an enclosed driveline is provided. The enclosed driveline may include a propulsion section, a power delivery section, a transmission section, a differential section, and in some cases, a second differential section. Failure of any component within any one of the various sections is inhibited or prevented from traveling from one section to another. Each section includes a first access and a second access in which power is input through the first access and output through the second access. In the propulsion section for example, there is a propulsion housing with a first propulsion access and a second propulsion access in which a motor drive input enters in through the first propulsion access and the motor drive output exits via the second propulsion access. The spur and pinion gears couple the motor drive input to the motor drive output within the propulsion housing.
