SYMA S107G RC Mini Gyro Helicopter

syma S107/S107G R/C Helicopter - Red

How is the progress? Did you try to make these flying machines? Today is another big day and we are going to have look about another great RC helicopter. SYMA S107G RC Mini Gyro Helicopter is commercially available complete helicopter model. But I guess you would like to assemble your own Gyro Helicopter, so that rather simply buy and fly your helicopter will make our own one, that will give more fun. Here I will discuss about the major components about this Gyro helicopter and how to assemble them to make your helicopter.

You can buy this helicopter from here Syma S107/S107G R/C Helicopter - Red.

Also you can buy individual parts and make your own helicopter. For this you don't need to make same helicopter you can come up with your own ideas as well. Why I am following this method is later you will understand that I will teach you how to make your own RC airplane. For that this knowledge is really important. Making RC from the scratch not a easy task, but that is again not a complex task if you have proper understanding. The objective of these tutorials to give you practical experience towards to make your own RC airplane.

In SYMA S107G RC Mini Gyro Helicopter, first we will identify what the major components of this helicopter. In helicopter Engine or Motor, Propeller, tail and tail propeller parts can be considered as major component of the helicopter. In this helicopter is also you have these components.

SYMA RC Helicopter S107-17 Motor

S107-17 is the main motor used in this helicopter. These motors are low voltage very high speed DC motors. Most of the time these kind of machines use Brussless DC motors, there are many advantages than normal DC motor with Brussless DC motors.

S107-18 Circuit Board is the brain of this helicopter. All main controlling functions carried out by this board based on the signals come from the remote controller unit. Connect other components such as motor, battery pack...etc is very easy with this board.

Main Blades Set

SYMA Replacement Set of Main Rotor Blades for S107 Red Part S107-02

There are four blades for this Gyro helicopter and all in same size. To reduce the size of propeller and reduce the torque for the motor they are using four small blades. You need to fix these blades with a main shaft and inner shaft to make the propeller for your helicopter.

Warning: As printed on each blade never touch these blades while they are moving, that will harm to you.

 3.7 Li-po 180 mah Battery for SYMA S107

3.7V Li-po Battery for SYMA S107 Original Factory Replacement Part S107G-19

This battery pack uses as main power source for the helicopter. This pack is rechargeable and you can buy compatible charger as well.

Inner Shaft

The inner shaft is used to fix four blades of the propeller and other end fix with the gear system of the helicopter.

Main Shaft

Main shaft and inner shafts are used to fix four blades and make propeller for the helicopter. Different between airplane propeller and helicopter propeller is; helicopter propeller can change while it is moving. Angle of each blade can be change to control the helicopter. To make this mechanism we use two shafts and small lever system.

These are the major components that you want to have make your Gyro helicopter. Other components you can select as you like, that will not directly impact on the performance of the helicopter.

This machine is little advance helicopter use and test it with proper safety measures.


  1. I've tried assembling a helicopter once but I failed since I lack 2-3 materials needed and it's not available in our place.

How To Make A Balloon Plane

Friends! How is the thing happening? Did you try the toy planes we make here? Today I am going to show another simple toy plane design that you can make very easily but have a great fun. Today we make Balloon Plane. You may wonder what this balloon plane is. This is again a simple plane uses the rubber balloon to generate throttle power. You know that once you fill the rubber balloon with air, inside the balloon air in under pressure. Once you release this air you can generate pressurized air flow from balloon’s mouth. This air flow can be used to push your plane forward very easily. Now you can imagine what I am going to make here. Even though this is a simple plane design if you control the air flow correctly you will be able to fly your plane considerable long air time. It all depends on the balloon size, straw size and length. You need to fine tune these parameters to get optimum flying time. That means if balloon is large we can expect long flying time. If straw size is small

Rubber Band Powered Rocket

Today I am going to introduce another simple but, very interesting toy. You might remember that we make a Paper Airplane few months ago. Today I am going to fly that paper airplane using a rubber band. If you did not make my previous paper airplane you can try it from here . You have to have that paper airplane to make this rubber band powered rocket. Fig 1: How to make a paper airplane As you can see in above picture, you need to make your paper airplane. Details instruction given in previous post . Then you need to have a little long rubber band.

Hanger 9 - Cessna 40 ARF, Value Series

In previous section we discussed about major components of radio controlled airplane. In this article will look at further details about Hanger 9 - Cessna 40 ARF, Value Series radio controlled airplane and how each of these components are fixed and controlled. In previous article I mentioned that we need few components to make a airplane. First we need to have structure of the plane, wings and tail. Then we need to have a propeller for your airplane and engine/motor to give power to the propeller. Finally you need to have a mechanisum to control your airplane. First I am going to discuss how to you can build structure of your airplane. Detail description of each component as follows: Center Wing Tape Center Wing Tape is used to fix wings with the body of airplane. You don't need to use this tape always, any light weight tape can be use for this. Center Wing Tape: Cessna 40 ARF Value
