A guide to buy and install rc cars

The purchase of rc cars can be a fun process. We can begin the selection process by choosing an engine that allows us to have an gratifying gift vs. weight ratio for our model.

Purchasing rc cars can be an witty procedure. You can prefer the best engine according to your needs. take on for example a model motorized sport that weigh a total of 1.1 kg takeoff. First, calculate the motor input power will be: 1.1 Kg x 200W/Kg = 220W (minimum). Then, if we used 3 series Lipo, this motor consumes a current of: 220W/11, 1V = 20A, therefore we should use a 25A or 30A ESC.

In models of more than 2.5 kg, we habit to consult the normal motor configurations to pick the ESC and Lipo, in the past in these sizes oversize equipment involves a significant additional cost. We used as the rc cars propeller first configuration specified by the manufacturer and, if possible, a smaller one that requires the maximum capacity the engine. After a few flights if we look that the temperature is not excessive, we can modify by a larger propeller. unconventional important consideration is infuriating to standardize the type of Lipo pack that we use, this will allow the similar pack may be used in several models.

The rc cars installation is an interesting process, too. First we must declare that the total should be without difficulty ventilated (motor, ESC and Lipo), especially the steer (ESC). The extra away from the ESC from the receiver and its antenna cable, the better. If we are converting a warm feeling model to electric, we must pay special attention to the location of the center of gravity. It is safer to stop using some ESC switches bring and directly off the battery after each flight. To accomplish this helpfully cut the 2 wires from the switch, colleague (or preferably welded) and turn away from the conductive part, see photo.

Here's the detail of an ESC where the switch has been removed desertion an on your own junction, and upon the additional hand, that the talent cord is remove and solitary tab. In large rc cars models it is advisable not to use the BEC (feed circuit that allows the pack to the radio lipo) and place the perpetual pack of 4.8 V to gift the radio. If the ESC has BEC and desire to use a remove pack for the computer, the cable that carries the distinct capability of ESC to heir (Futaba red) should be cut or removed from the connector, look picture.

Inside, to prevent accidents and as a golden rule, we must not be next to the ESC without having removed the propeller. Electric rc cars motors, unlike the glow, not dependent upon outside elements to boot. If you accidentally touch the throttle pin the motor begins to rotate. This accident is typical subsequently scrutiny the course of the servos.
