Walkera 4G3

With small in size, the Walker 4G3 helicopter is also very light and there is no need to perform many actions to control it and when you are flying it in idle up mode, it really gets more interesting. You can easily perform 3D actions like flips, loops, invert flying and rolls, if you are flying in a big area.

Despite the size of servos, they are very fast and have a very good functionality and if we can add some more torque, it will become even better.

The 4G3 is very good and in forward flight and it will fly straight as you command, although it loose some torque in difficult turns. There is a small slope in the head of 4G3 where the aluminum head part will be fixed.

As we know that 4G3 has a light weight, it has very little resistance to wind and it will not be a good idea to fly it outside when the wind speed is more 7mph. Therefore, don’t fly this outside on windy days and even in cloudy atmosphere. A good sunny day may prove to be a great opportunity to fly it outside.

An individual brushed motor runs the tail motor which is not enough to keep up with 4G3 all time. On some occasions, 4G3 will have a little lag when taking turns. You can also make some adjustments in gyro sensitivity, compensation and tail mix. The gyro of 4G3 is suitable for its size, but the gyro is not sufficiently sensitive and when the head speed reduces, the tail begins to drift some. Moreover, the full speed of 4G3 in flight experiences some changes in its RPM. Also, some parts of 4G3 are very fragile, so make sure to get some spare parts for the 4G3, just in case if any part is broken. The following parts are more important to get in spare:

Flybar

5 or minimum 3 sets of main blades.

Screw supplies

Linkage set

Additional batteries, if you want

Case for batteries

Additional tail blade(s)

If these things are affordable for you, then you should better buy them. Otherwise, if it’s out of your budget, then leave it for later.

Although, this helicopter is small, but this doesn’t mean that its flying capabilities are small too. The 4G3 is very good in flying and has an ability of giving a smooth flight experience. Although, controlling this helicopter is not easy at the beginning but once you are use to this, you will enjoy flying 4G3 easily. However, to constantly keep this helicopter flying, you have to keep controlling it; it won’t keep flying on its own.

The rotor wash in this helicopter produces some ground effect, so don’t fly this helicopter too high, keep it few feet above the ground. This is because, if you fly too high, it will become unstable in strong wind because it is very light in weight.

As I said earlier, a beginner will definitely going to have difficulties in flying 4G3 and he/she cannot fly it too high. Otherwise, if you are a expert or at least you have an experience in this, then flying 4G3 smoothly and high above the ground may be a piece of cake for you.

Flying Walker 4G3 is like playing the flight simulator video game. Flying this helicopter will be a good practice and a good experience.

Many people think that after buying Walkera 4G3, they have to do very tiring process of assembling the helicopter and other troublesome stuffs. Therefore, let me tell you that, 4G3 is comes in already assembled shape and there is no need to do any tiring or troublesome stuffs. Although, it needs of tuning and adjusting and this is not difficult, boring or laborious. It just needs some tuning and it will be ready to fly around you.

Total length is 273mm – Total weight is 68.4g, including battery – Diameter of Tail Rotor is 58mm – Diameter of Main Rotor is 302mm – Servos with speed of 0.12sec/60o, weight of 3.5g and torque of 0.2kg/cm

Battery

This small helicopter needs the mini LiPo batteries with 400MAh single cell 3.7 volt power. This battery gives 4G3 the power for 8 minutes easy flying in normal made and 5 minutes 3D flying in idle up mode.

The only issues, regarding the battery, reported so far are that the battery holder is fragile and can be broken in hard landing and also the battery keeps falling out. The battery connectors are also very tight and it is difficult to separate them.

The Box Contents Of Walkera 4G3

Including a pre-assembled 4G3 helicopter itself in the box, there are also

A battery charger

A 6 channel 2.4GHz powered radio

An adapter wire for simulator of flight

A 400 MAh with 3.7 volt LiPo battery

An instruction manual of course

A screw driver made of plastic

An additional collection of main blades. That’s all.

The newly released Walkera 4G3 is credited as the micro type helicopter and till now it the tinniest existing 6 channel fully operational RC helicopter in the market. Despite its small size, it has all the functions of big helicopters. The Walkera 4G3 is so small that even flying it inside your house is not a problem. However, flying it inside your house or any small area will not bring out the full potential of 4G3. Since the 4G3 is small, it speed is very fast and it can go very far and higher, therefore, a big area will be good to enjoy the full experience and excitements of flying Walkera 4G3. Also, before you fly 4G3 outdoors and in big area, you should get used to flying it and become a skilled pilot of 4G3 in any safe area.
