How To Build A Remote Control Vehicle From Scratch

Creating a remote control vehicle from scratch is rewarding and a lot of enjoyable.  Kits are simple.  But there is nothing like the satisfaction you get when you turn on a car and drive it for the first time right after building it from scratch. Making your own remote control car from parts you buy separately permits you the freedom to customize your auto.

Style and Scale

Commence with a sketch of what you want your automobile to appear like. Determine on the scale most remote control vehicles are 1/10 scale and off road vehicles are typically 1/18.  Begin by sketching out the frame and draw it from different angles for an idea of how to begin to assemble your auto. Experienced hobbyists suggest measuring from the wheels of the vehicle. The frame serves as the connection point for almost each and every part of your car, so make sure that your measurements are accurate.

Creating the Vehicle

Hobby stores will have all the parts that you want to develop your own custom radio controlled automobile. Some hobbyists use parts they have from older vehicles to assemble a new one.  When it is time to assemble your car mark you parts will be clearly as proper (R) and left (L).  Some parts will require glue. It is a very good concept to use a clean plastic lid or bin to hold a few drops of glue and then dip the component in the glue when ready to assemble the parts.

Assembly

Start with a flat metal plate measured and cut to the scale you determined by your drawing. You will want two axles one straight axle for the rear wheels and one with pivoting ends for the front to steer the auto. The motor will be attached to the front axle as nicely, so make positive that your scale is big sufficient to hold the size motor you want to install. Use screws to attach the axles to the metal plate and coat the ends of the axles with graphite so that the wheels will slide onto the axles less difficult.

Just before assembling the wheels, make certain that the steering knob and the gear assembly are effectively installed. These parts will turn the axle and propel the vehicle. Use washers on the ends of the axles to hold the wheels in location and keep them from sliding on the axles. Install a copper ring to the front axle that will be employed to transmit electricity from the motor to the wheels to propel the vehicle.

Subsequent, bolt the motor to the front of the frame plate close to the front axle. Attach a lead wire from the motor to the copper ring. Attach the steering wire from the motor to the gear assembly on the front axle. Twist the wire around the steering knob and crimp it securely. Lastly, attach the radio control antenna to the best of the motor.

Just before installing the motor, make sure that it is properly centered by marking the output shaft center position. Bundle the servo leads by coiling or zip tying. To correctly coil the leads, wrap them about a screwdriver shaft and then plug them in. Longer lead wire should be folded over itself ahead of coiling with the other leads. Zip ties function well to hold the coiled wires securely. Trim off excess plastic from the zip tie. The servo ought to be assembled level with the engine. The lower the center of gravity (i.e., the lower the servo is mounted on the frame), the quicker the vehicle can take corners with no rolling.

Creating the Remote Control

Develop your remote control trigger device from parts that you can recycle from old remote controls or get the plastic housing from a hobby shop. Utilizing rubber cement, glue two resistors to the inside of the housing. Drill a hole between the resistors and location a steel rod about four inches extended although the hole. Then attach a rotating head with an electrode to the finish of the steel rod. The head rotates between the resistors and creates an electrical connection. The electrical signal is transmitted from the trigger to the antenna on the auto, which then responds with the servo which turns the wheels left or correct. Wire a trigger to a resistor by wrapping the edges of the lead wire about the resistor. The trigger determines how quickly the vehicle will go. Lastly, attach the antenna, and then seal the plastic housing.
