Xieda 9958 is 4CH single rotor 2.4GHz flybar heli by Great Wall. It is extremely strong and durable and very suitable to those who have flied coaxials before. With a mix of some certainty and some uncertainty, it is a fun heli to try your hands at.

Packing and Looks

Packing of GW Xieda 9958 is great! A two piece foam tray holds the ensemble of the heli snugly, packed again inside a strong cardboard box, with a handle for carrying. The pack includes 1 pre-assembled Xieda 9958 heli, 2.4GHz transmitter, 1 150mAh Li-Polymer battery, 1 USB charging cable, 2 spare main blades and an instruction manual. The heli is quite pleasant-looking.

Quality of Structure

Quality of 9958’s structure is good. With battery, its weight is 32.4 gm (without battery, it’s 27.7gm). Finishing of the heli is superfine, for all parts to fit in each other nicely. All parts are strong and durable.

You will have to solder the antenna wire again to the board, because it falls off and the heli flies away. The glue is not a good adhesive, so, while flying outdoors, check the antenna well.

The canopy is kept in place by 8 rubber rings, similar to those used on the NE Solo Coaxial. These rings are easily detachable and slip off in crashes.  

However the heli itself is fairly crash-resistant. However, some parts are weak, like ball joints of main rotor. They come off readily just on applying pressure. One solution for this is, while removing the head, do not to take them off from the blade side, but from the flybar side. Other weak part is in the upper rotor head assembly. It has two holes in which the main blades’ pins slot in, and the covering of these holes is weak too and can break upon just a small bang.

Height – 15 cm

Weight – 32.4 gm (with battery)

Transmitter – 2.4GHz

Battery – 3.7V 150mAh Li-Po

Tail

Tail of 9958 comes off upon a crash. You will have to constantly check whether tail fin is in place. The tail is short, but it holds very well.

Battery

The 150mAh Li-Polymer battery of 9958 has built in voltage safety circuit, making it weighty. (It is not in the charging cable, making the cable unsafe for charging any other battery.) The white connector on this heli is similar to that of E-Flite micro-helis, like mCX, so they can be used for each other. Both 130mAh and 160mAh Turnigy Nanotechs by Hobby King work well with 9958.

Battery skids are prone to pop off in crashes, but can be placed back easily and can also be attached with glue.

Transmitter

Transmitter size is nice and you feel good holding it. It is 2.4GHz, takes 6 AA batteries and has a USB port at the bottom to charge the Li-Po battery of the heli. It features digital trims and dual rates, activated by keeping on the left throttle stick pressed down. You can even hold the stick down when you turn the transmitter on so as to start a binding process.

The center of rudder trim isn’t identifiable; its beep is same regardless of the situation, thus you cannot find where the trim can be. However the other three trims make twin beeps at center; only the rudder doesn’t.

Flying Experience

An outstanding feature of 9958 is it is absolutely noiseless. And it is also extremely smooth. Plus, it is very fast and you can fly it outdoors, even in winds. Pirouettes and climbing power are more than sufficient. Tail holds extremely well and flight time is great.

You may come across a little TBE, though not uncontrollable, if you work more on sticks.

You also need to work on cornering; the tail slips as if it is underpowered. But you will also find that once you get used to flying it, cornering will become quite fine. Everything matters in flying 9958 is practice. During full forward flights, its nose may turn to ground, swooping the heli down; in such a case, you should increase the throttle much more to make it more manageable, or pull back the elevator. This tendency of moving down is, however, helpful for outdoor flying in winds. On the approach of turn, the heli will start moving upward. In such cases, take corners broad, apply more aileron and less rudder, for better cornering.

You will also have to remember that this heli being very fast, isn’t responsive to input instantly and so, you should fly it that way. This means that you will need pre-planning of your maneuvers, so that you will achieve them successfully, when you want them and if you practice this, you will find 9958 mind-boggling. With so much of controlling challenges, you will find fun flying this heli.

Comparison with Competitors

9958 has similarity of the head assembly to that of the Blade mSR. Actually the heli is a combination of mSR and mCX, with some changes, like a heavy flybar unlike the paddled flybar of mSR. The swashplate looks same like mCX. The control balls are larger than those of Blade’s helis.  One scoring point of 9958 over mSR is its fine course of wires through a channel and the flap at the end doesn’t allow the cap from coming off.

Its responsiveness is not at par with Solo Pro, as it just goes on like slipping and you need to pay attention to its every action.

Flight performance is not as excellent as that of CB100 or Solo Pro, though it is a real fun heli to fly, particularly with that price. In all, it is quite similar to 9C002. 9C002 has better stability and cornering, but it is also boringly slow.  

Spare Parts Availability

Spare parts of 9958 are not easily available. So, ensure to store a lot of them, whenever you get them. You can also replace some parts with that of mCX2 and mCX, like lower blades.

Pros

  • Both, heli and its spare parts are very low-priced.
  • Offers prolonged flight time
  • Absolutely noiseless and extremely speedy
  • Looking at the price, quality and structure are really nice.

Cons

  • Poor cornering. Needs a lot of practice for that, and still after that the heli doesn’t corner very nicely, as expected.
  • Spare parts are not widely available and their packing is mediocre, in zip-lock plastic bag, having no labels.
  • A slight TBE and pendulum effect (swooping up and down) can be there.
  • Safety features are absent. No automatic disconnecting in case of signal loss. The USB cable doesn’t possess a voltage protection circuit, but battery has it. If the throttle stick is elevated upon starting the heli, it will power up and if the signal is lost between the transmitter and the heli, it goes on flying. And also, you cannot charge any other aftermarket battery randomly with the charger of 9958, without ensuring about its safety.
  • Because of lack of a plastic stub, the antenna commonly loses signal during outdoor flying, where there may be a lot of signals and the heli flies away.  

Conclusion

This superfast heli is good for experienced pilots. They will certainly enjoy flying it. However, it is hardly recommendable for learners.
