Walkera 4G3

MIA TUFF (trade mark.) introduced a LG upgrading Kit known as “4G3” and it is basically for Walkera 4G3 – 3D helicopter and also a kit for saving helicopter. Change the thin wire of landing gear of heli with the long lasting and durable one. This 4G3 kit is with G10 battery which provide support to plate and it is designed in such a way so the different sized batteries can forward positioned or can be rearward position so it easy to adjusting in the center of Gravity. There is another option that you can use cage of plastic battery but this cage is limited to Central Gravity adjustment because it make the tail of helicopter heavy.

The strut of G10 provides supports and the plate of battery frequently assembled by using glue, further assembly install to the bottom of stock of plastic frame by using stock of cage of battery mounting screws, skids and the struts are properly installed and then press-fit.

The 4G3 saver kits for 3D helicopter includes several things and these things are mentioned below in detail:

2 Struts of MIA TUFF (Trade Mark)

1 G10 Battery Support Plate of CNC Machined

2 G10 Strut Supports of CNC Machined

2 G10 Skids of CNC machined

2 Battery Support Bands

4G3 Air RAM Kits of Fins and Canopy:

4G3 Air RAM kits of fins and canopy by MIA Phantom and generally it is for the Walkera 4G3 – 3D helicopter and this 4G3 kit provide your 3D helicopter more cooling with the canopy of air scoop. This canopy designed in unique shape and fixed with the 4 air scoops which provide air ram into motor and the battery keep on cooling them. The cooling of the motor is really important and it is very much effective when your are flying the heli in fast forward. With this 4G3 air ram kit it keeps the motor cool and heli get quickly balanced because of the placement and unique shape of top side air scoops.

There is another great advantage of 4G3 Air RAM kits is that the opening of Air RAM can use for the placement of LED lights which provide a good look in the visual appearance of helicopter.

The 4G3 Air RAM kits of fins and canopy includes several accessories and these name of these accessories are as follow:

Air Scoop of Canopy Style

Decorative Decal well Finished Trim Sheet

Supports of Mounting Rubber

Vertical Stabilizer

Until now, only a metal head made of aluminum has released. This consists of mixing arm, blade grips, rotor housing, swashplate and linkages. Unlike the plastic parts, the metal is very detailed in design and fills much of the slope which has made the cyclic more sensitive while adding only 1 gram of additional weight in the total weight of 4G3. This head piece cost around $50.

Another improvement might soon be released. It is a scale canopy bodies to give your 4G3 a more micro scale look. Also, rumors has it that a brushless improvement will be coming too.

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.
