Stakeholder/Customer Needs

There are a few stakeholders that need to be considered when designing and manufacturing a Nitro RC car. First, raw material users in the company that provide the parts made of plastics, metal and rubber. The design of the parts should not be too complicated that injection molds are adequate for the scale of part. If parts are small, it may be difficult to make an accurate mold of an important small part. With design for manufacturing in mind as well, there should not be too many different parts to be molded making it easier on component producers. Next in mind are those who assemble the cars. The design of the RC car must be easy because there are many parts. The parts cannot be too hard to assemble together because of positioning or the size or placement of necessary fasteners. Again, similar parts are important for assemblers because it may be hard to distinguish very similar parts in assembly that may make a big difference if assembled to wrong way. Finally, the end product is important to the customers who buy the RC car. Since we are considering an off-road RC car, the product has to be durable through a significant lifespan. The car has to be built for off-road rock crawling and tricky terrain. The car also needs to be easy to fix, modify or replace parts if broken.

Product Use and Function

Our particular product is a 4x4 remote control truck Wheeley King. It is an entry car for those interested in off road RC. The car is used and designed to crawls rocks and scale inclines with tricky terrain. These cars are not built for speed. They should be built to be durable because of the tough terrain it will be used on and should be durable for novice operator who are not as skilled and may damage the car easily. RC cars need to be built to be easily modified for improvement if someone chooses to improve the performance of their car.

The RC car runs off of a rechargeable battery. The battery supplies a Sturn motor. The motor is geared down to provide more torque to the tires so that the motor can handle the tough forces that an off-road RC car may encounter. Power is distributed to front and rear wheels, making the car 4 wheel drive. Differentials located on front and rear axles allow for powered turns and more power supply to a slipping wheel. The car is designed with a wide wheel base to guard against rolling. The wheel base also twists and has shocks to adapt to rough terrain to allow for reasonable traction on many types of uneven surfaces.
