Project info:
There is a need to design a drivetrain, chassis, steering, and suspension for an RC race car to compete against other RC cars in an array of racing competitions including Acceleration, Slalom, and Baja. Work on the project will be divided between the Drivetrain/Chassis and Suspension/Steering

Function Statement
Devices are needed to make our RC car drive by applying power from the motor to the wheels as well as a chassis to hold the cars components together during 3 different races (Acceleration, Slalom, and Baja) and figuring out the best overall design to manage each style of race, all while competing against other race teams

Requirements
-
The car must be conceived, designed, and fabricated by students without any direct involvement from professional engineers, automotive engineers, or related professionals.
-
One propulsion motor per vehicle: Any motor which conforms to current-vintage ROAR brushed or brushless specifications and manufacture is legal.
-
One battery per vehicle: any 7.2 volt battery-pack intended for RC use.
-
Baja TIME-LIMIT, equivalent to running the full course at 1.0 MPH.
-
Car must weigh under 5 pounds.
-
Must be able to sustain 25 mph at full speed.
-
Keep cost below $500 for Drivetrain and Chassis.
-
Drivetrain height restriction of 3 inches off of chassis base.
-
Battery will sustain power for 10 minute to motor at full power without dropping RPM’s
-
Motor will maintain a temperature below 150o F at max load.
-
Construction, mounting, and deconstruction of the entire drivetrain will take less than 10 minutes to keep design as simple and as resistant to failure as possible.
-
The motor mount with gears mounted will be able to tension the timing belt.
