The top radio control helicopters with extreme precision

Most radio control helicopters can be modified. You can find and or create an interesting voltmeter on board, absolute precision of only two visual indicators. This allows a very simple interpretation, as the truism given the time. In contrast, bright red indicates not flying.

Batteries and circuits

The transition from green to red occurs when the voltage level per cell is 1.05 volts, i.e., 4.2 volts total for a 4-cell pack, and 5.25 Volts for May 1 cells, voltage thresholds, where the discharge curve begins to be abrupt, and therefore very dangerous to fly with low voltage receiver and servos. While the latter, then causes a slow transfer speed in the radio control helicopters receiver. It dies at 4.2 volts, because the internal voltage regulator fails to fulfill the role of regulation because it works with 3, 6 Volts internally, consuming 0.7 Volts in this process.

In the case of 5 cells, we believe that the higher voltage pack may be good. We are more protected. The slope of decline is ahead, but falls at last. It only serves to have more torque servos. Although not presented problems this excess tension receptor has been observed chats or "jitter" when the voltage exceeds 6.4 volts, so that you are using an external controller to the receiver of 5.6 Volts to avoid.

While, according to some opinions, experts concluded that it is far better to separate the radio control helicopters receiver's power to the servos (in another article we will show you how).

The connection is very simple voltmeter must be connected just like a servo, a free socket on the receiver. Do not use "Y" or strip the wire from the battery. Consumption is negligible, pretty much half of what it consumes a servo at rest, it is not necessary to cut key, there is always fed.

The best time to test visually, the return flight is basically the first flight, as consumption is the one ultimately submitted to the pack. Move all servos at a time and see if the green LED is lit, if it appears that try on both at once, or off the green and red lights, better not try to fly, because there is no return. If you want to do a manual voltmeter should put a resistor in parallel with the power to induce consumption and achieve an effective measurement. It is advisable to tight the components on the same radio control helicopters integrated circuit, will be safer and once completed and tested, it should be sealed with resin or plastic melted to pack.
