Chances are high that you have seen how powerful RC drones are on TV, but you never knew anything about 27 MHz RC receiver. In this piece, you will learn all you need to know about RC drone receivers. You will understand the frequency which is used by remote-controlled drones and what the components are. Also, you will learn the difference that exists between the remote control and radio control.

Understanding how RC receiver works will help you better appreciate your remote-controlled device and be able to escape from issues as they arise.

What are the components of the RC drone?

Remote controlled devices come in different models such as drones, trucks, cars, airplanes, blimps, helicopters, robots, and even animals. Even though their mechanics for functioning differ, they operate on the same basic principles. All RC drones come with the following four components:

  • Transmitter

The transmitter is held in the hands to control the RC drone, it helps in sending Radio waves to the receiver.

  • Receiver

This comes with a circuit board and an antenna inside which helps in receiving the signal from the transmitter and thereafter activates the motor that is within the drone as it is commanded by the transmitter. An example is the 27 MHz RC receiver.

  • Motor

 The motor can navigate the wheels, operate the propellers, and steer the drone.

  • Source of power

The transmitter relays the control signal to the receiver through radio waves which in turn drives the motor. The motor that is within an RC drone may cause the wheels to turn even as the motor inside the drone adjusts the flap. The source of power is often a rechargeable battery pack even though it is sometimes an ordinary batter.

In several RC drones, the motor gives the needed guidance while a different power source handles the locomotion.

RC toy receivers

The average RC drone has a handheld device that includes the radio transmitter and some type of control. What the transmitter does is to relay a signal over a certain frequency to the toy's receiver. Usually, the receiver has a source of power which gives it the much-needed power for the transmission and control of the signals. The biggest difference that exists between remote-controlled and radio-controlled drones is that the remote-controlled drones come with a connecting wire that connects the toy and the controller. The radio-controlled drones on the other hand are wireless.

Note that majority of RC drones use either the 27 MHz RC receiver or the 49 MHz. this frequency pair has been giving by the FCC for use in certain consumer items such as RC toys, and garage items.

Note that most drones get labeled using the frequency they operate upon. Several RC drone manufacturers create certain versions of the model made for dual-frequency ranges 49 MHz and 27 MHz. with this, you will be able to safely operate both models without the challenge of interference between either receiver. Certain manufacturers provide certain information regarding the frequency band which the toy works on.

Buying guide to RC receivers

Understanding how RC receivers work will put you in better stead as you venture into your RC adventure. Knowing what to buy with regards to the receiver will help you make better-informed decisions in that regard.

  • Go for a trusted brand

As it is with buying any commodity, it is essential you only purchase an RC receiver brand that is tested and trusted.

  • Function

Before you buy the receiver, you need to define what you want to use it for. Ideally, go for a receiver whose range suits your requirements.

  • Cost

The cost of the receiver is perhaps one of the most important factors. Make sure you do not exceed your budgetary projections before making the purchase.

Understanding transmitters

RC transmitters are either full-function controllers or single-function simple controllers that come with an array of options. A typical instance of a single-function controller is those which make the toy move forward as soon as the trigger is clicked. If you want to stop the toy, you will have to turn it off. The majority of full-function controllers come with six distinct controls namely: the reverse, forward, forward and left, forward and right, reverse and right, reverse, and left.

In the majority of full-function controllers, not clicking any button or knobs leads to the toy stopping pending further command.

Final thoughts

The average RC drone owner hardly bothers themselves about the RC receiver and other components. Most people just want to turn their drones on and move! But understanding how the components work will help you better manage and exploit their potentials.
