RC Helicopters

Helpful information on RC helicopters. Our electric remote controlled helicopter models are safe, convenient and fun to fly practically anywhere.


The BladeRunner Micro Mosquito Indoor Electric RC Helicopter

The BladeRunner Micro Mosquito is an indoor electric RC helicopter designed to be easy to fly and fully maneuverable.

The Micro Mosquito uses a coaxial, dual rotor design to provide both stability and directional control. Two main rotors are mounted on the same axial and spin in opposite directions. This provides twice the lift of a conventional, single rotor design and also self stabilizes the RC helicopter. Each rotor is driven by a separate motor, so their speed can be varied individually. The Micro Mosquito uses this to control its yaw. The yaw can be controlled with the main rotors, so the tail rotor can be used to control the pitch. This lets the Micro Mosquito maneuver freely in three dimensions and even hover and fly backwards!

Due to its extremely small size, the Micro Mosquito can fly almost anywhere. The included green eyes glow very brightly and can even let you fly at night!

Replacement parts for the Micro Mosquito are available on our website, including rotors, tail rotors, and every other component of the Micro Mosquito. We recommend that you get some of the most frequently broken parts when you order the Micro Mosquito, so that you will have replacements ready when you need them.

The BladeRunner Micro Mosquito makes is a great way to have fun flying RC indoors. No previous flying experience is necessary so everyone can have fun flying this neat little RC helicopter.

Set Of Two Main Rotors For Your Micro RC Helicopers

The K-DF-MINIHELI-ROTOR-2 is a set of two main rotors for your micro RC helis.

These rotors are able to fit any palm size mini two channel RC helicopter, just remove the broken rotors and then press the new ones on to the main shaft. Be careful while doing this, if you push or pull them too hard, you can damage your helicopter and break the rotors.

Each rotor is equipped with a pair of small weights on the bottom of the top section. These weights help stabilize the helicopter, so you will need to replace the main rotors if they are missing.

Use this set of main rotors to replace the rotors on your micro RC helicopters if they break. It is a good idea to buy the replacement rotor set ahead of time, so that you have them when you need them.

Fixed Pitch RC Helicopters Explained

Draganflyer RC Helicopters use Fixed Pitch Design All RC helicopters need a way to control their altitude and direction. In most cases, this is accomplished by altering the angle (pitch) of each rotor blade. The resulting change in airflow from the blades causes the RC helicopter to move in the desired direction. Changing the pitch of the rotors provides very fine control. There are ways that an RC helicopter can be built that eliminate the need for pitch control. These fixed pitch RC helicopters are a great way to start flying rc helicopters, because of their simplified controls and low cost. In this article we will look at how they work, and see some good examples of this design in actual RC helis.

How Fixed Pitch RC Helis Work

In order to understand how fixed pitch RC helicopters work, it is useful to consider a fixed wing aircraft. Airplanes can fly because air moves over the wings, resulting in a difference in air pressure between the top and bottom, which causes lift. To increase the lift we can do one of two things. The speed of the air moving over the wings can be increased, or the curve of the wing can be made steeper. If we think of the rotors on a RC helicopter like the wings on a plane, the easiest way to increase lift is to cause them to spin faster. This will send the helicopter upwards. When the helicopter needs to descend the rotor speed is decreased.

Quad Rotor RC Helicopter Design

Draganflyer V Ti Fixed Pitch RC HelicopterSome RC helicopters are built using four main rotors, each mounted at a right angle to the aircraft. This design allows four channel control, without the complexity of variable pitch. A flight computer can read the input from a radio receiver and then change the speed of each motor accordingly. Using a flight computer also allows automatic stabilization of the helicopter. The flight computer is a sophisticated circuit board, which is capable of changing the motion of the helicopter under different conditions. This makes quad rotor helicopters perfect for aerial video and surveillance. The Draganflyer helicopters use this design, and are available in several different models.

Conventional RC Helicopter Design

There are two ways in which a fixed pitch RC helicopters direction of travel can be changed . If we include a rear rotor, which is mounted at a right angle to the fuselage (body of the helicopter), we can use it to push the helicopters nose in the desired direction. Our Mini Bell Helicopters are a good example of this design, and are able to be built to very small dimensions because of the reduced complexity.

Coaxial RC Helicopter Design

We can also use two main rotors, each linked to a separate motor to turn the helicopter. By spinning each rotor at a different rate, the yaw (direction) of the helicopter can be controlled. Our Bladerunner Series and Lama V4 R/C helicopters use this fixed pitch coaxial design. Each rotor can be placed on the same axial. This reduces the size of the helicopter, so that they can be flown indoors. Learn more about coaxial helicopters.

Another benefit of the fixed pitch coaxial design is that it frees an extra channel of control. If we don’t need to control the direction (pitch or yaw, depending on application) of the RC helicopter with the tail rotor, we can mount it in the same direction as the main rotor blades, allowing pitch control. This design is found in our Micro Mosquito RC helicopter, where two main rotors are complemented by a tail rotor.

Benefits of Fixed Pitch RC Helicopters

  • A minimal amount of parts are required because of the simple fixed pitch design
  • Repairs are simple, because there are few moving parts
  • Some fixed pitch RC helicopters can be flown indoors.
  • The Draganflyer RC Helicopters are an excellent choice for aerial video because the coaxial design gives stability

How Coaxial RC Helicopters Work

Chinook C-47 HelicopterWhat is a coaxial RC helicopter? There are several different approaches to coaxial rc helicopter design. There are two main ways that the main rotors of a helicopter can be mounted. In conventional helicopters, one main rotor is mounted on top of the fuselage, and a smaller tail rotor is added to the end of the tail boom. In this system yaw is controlled using the tail rotor, and every other aspect of flight is controlled by altering the pitch of the main rotor blades. It is also important to have a tail rotor so that the torque from the main rotors can be canceled out. Torque is caused by the main rotor spinning in one direction. Because of Newton’s laws of physics (for every action, there is an equal and opposite reaction), the nose turns in the opposite direction.

How Coaxial Helicopters Work

Instead of using the tail rotor to control the yaw, two main rotors can be mounted on the helicopter, and spun at different rates. The thrust difference will cause the nose of the helicopter to turn. This duel rotor design is employed in several full scale helicopters, including the CH-47 Chinook, frequently used as a military
transport helicopter because of its immense lifting capacity. The same principle applies to remote control helicopters, but most of the time we choose to mount each rotor on the same axial, hence the term “coaxial”.

Paired rotors spinning in opposite directions

The rotors of a coaxial helicopter need to spin in opposite directions to cancel out the gyroscopic force. On some helicopters, both rotors are on top of each other The main axial of a coaxial helicopter actually consists of two separate axils, one mounted inside the other. Each sub axial is connected to a gear at the base of the shaft, and each gear is attached to an electric motor. These two motors operate independently of each other, so varying the speeds of each rotor is possible.

Since the rotors need to spin in opposite directions, the top and bottom rotor blades are curved in opposite directions. This is because each rotor needs to be pointed into the air flow in order to work. The bottom rotor usually rotates in a clockwise direction, while the top rotor rotates in a counterclockwise direction. It is important to note this if you need to replace your helicopters rotor blades. Your helicopter will not fly if they are installed incorrectly.

Two Channel Coaxial RC Helicopter Design

Firefly RC Helicopter

It is possible to build a coaxial helicopter so that it only needs two main rotors, and eliminate the tail rotor entirely. Tilting the main rotors forward slightly, results in a constant forward movement. An excellent example of this simple design is our Firefly RC Helicopter, which is recommended for beginners due to it’s simple controls.

Three Channel Coaxial RC Helicopter Design

Micro Mosquito

There are other cases where a tail rotor is still added to a coaxial rc helicopter. The tail rotor is placed in the same direction as the main rotors. This allows pitch control, so the forward and reverse rate of the helicopter can be changed. This means that you can fly backwards, forwards and even hover. The Micro Mosquito rc helicopter uses this design.

Four Channel RC Helicopter Design

Esky Lama V4 RC HelicopterEven though the coaxial design is most frequently used in small, fixed pitch rc helicopters, it can also be used for models with cyclic collective pitch. The only difference between these models and the conventional designs is their lack of a tail rotor. As with the models above, yaw is controlled by changing the rate at which each rotor spins, but the rotors can change their pitch. This allows the helicopter all four degrees of freedom: pitch, bank, throttle, and yaw. The Esky Lama V4 uses this design, making it a good all around RC helicopter.

Benefits Of The Coaxial Design

  • The simple design leads to a low cost.
  • Because yaw is controlled with the main rotors, pitch can be controlled with the tail rotor.
  • This design produces a great amount of stability.
  • Because they are stable, these helicopters are a great way to learn how to fly.

How to Pair Each Mini Heli Laser Battle So They Fly Independently – Important Startup Procedure

You must pair each helicopter to its remote control each time you turn it on.

Each Mini Heli Laser Battle Helicopter can actually run on any one of the 3 channels and be controlled by either one of the two transmitters (black infrared remote controllers). Each time you turn the helicopter ON it automatically locks itself to whatever transmitter it first receives a signal from. Each time you turn the helicopter off it resets itself and looses this assignment.

Please follow these instructions each time you want to turn the helicopter on.

  1. Make sure both remotes and both helicopters are turned OFF.
  2. Pick a remote, set it to “Channel A” and turn it on.
  3. Pick a helicopter and turn it on.
  4. Push up on the left stick on the remote to make the rotors spin a bit.
  5. Now this helicopter is paired with this remote and ready to fly on Channel A. Now do not touch the controls on this remote until after step 10.
  6. Wait at least 5 seconds.
  7. Take the second remote, set it to “Channel C” and turn it on.
  8. Get the other helicopter and turn it on.
  9. Push up on the left stick on the remote to make the rotors on this helicopter spin a bit.
  10. Now this second helicopter is ready to fly on Channel C.
  11. Start your super battleplanes!
