Walkera Scout X4 & Walkera Tali H500, Which is better?

We have had quite a few friends asking us should they choose the walkera scout x4 or walkera tali h500, which is better. This is actually not a very complicated question, it depends on how you want the copter to be, we will just state some of their differences.

The Walkera Tali H500 is 6 axis, 6 axis is more stable than 4 axis, this is unquestionable; both of them are compatible with gopro camera; both of them are using a 22.2v 5400mah battery; Walkera Scout X4 is more expensive, but it’s equipped with ground station, you can even control it with ipad if you like or your transmitter is taking a break…

In conclusion, the Carbon version Scout X4 looks really cool, powerful and more expensive, H500 is more stable, and it depends on which you like

During the setup procesure of the tarot zyx gyro, the first step is to check if the copter could fly normally, then we will set it up step by step following the instruction.

http://www.oomodel.com/tarot-zyxs2-z...3-p-66087.html

1. Set up for Helicopters
Firstly, check the body of the rc helicopter to make sure all the components on it work properly.
Secondly,Check if the main shaft and tail shaft are even before install the central part of the main shaft;put the throttle at the lowest position, turn on the transmitter and receiver; Hold the skid landing of the helicopter with one of your hands while put the throttle up little by little, the motors are working now, you need to check if the main shaft and tail shaft are even, if there is no shakes then it’s normal.

2. Set up the zyx gyro

1. Set the transmitter up according to the manual;
2. Set up the gyro step by step according to the manual.
3. You will finish it smoothly.

Tips:

Set the medium point pitch to 0 degree;
1. Enter the throttle curve menu on the transmitter and put the throttle up to 50%;
2. Adjust the linkages to make sure the pitch will be kept at 0 degree.

The Walkera H500 Quadcopter is known as a very good all-in-one fpv set, it’s well-equipped and very stable, a middium size 6 rotors multicopter, a few days ago, one of our customers run into a problem in unlocking the walkera h500, he tried quite a few hours in different method with no success. Finally we decide to try this copter with another radio and it worked properly which made it looks really wired. We then compare the parameters in the 2 radios and finally found out the problem. Note: the radio we were using were walkera devo f12e(http://www.oomodel.com/walkera-devo-...o-p-66903.html), but it will be the same for other walkera radios.

There are a few trimmers on all the walkera radios, and each of them performs different functions. We tried out that when we turned the throttle trimmer to a certain value, such as 80 or above, then it’s unable to unlock the quadcopter, but when we turn it to 50 or bellow, we have no problem unlocking it.You may try it if you have problem in unlocking your walkera quadcopters

Many people told us they've been thinking about get an all-in-one FPV multicopter, not sure which one to go, especially don't know if the dji phantom 2 vision + or the walkera tali h500 will be better, here bellow we will make a basic comparision between them.

We do think DJI is more reliable as there are more people are flying them, they've been tested more than enough. But it's hard to make a final decision as the dji phantom 2 vision + is 4 rotors, while the walkera tali h500 (http://www.oomodel.com/tali-h500-wal...1-p-66922.html) is 6 rotors multicopter, the 6 rotors will be more powerful and also bigger in size.

Walkera h500 also has its advantages, such as it's camera can be changed to gopro, while dji phantom comes with it's camera and can't be changed, and the walkera radio is more professional than dji,but the dji phantom is compatible with futaba radio. Also it adopted 22.2v 5400mah battery which will provide a 20+ minutes flying time, while dji phantom adopted 11.1v 5200mah battery which provides around 15 minutes.

People say if we say the dji phantom 2 vision + is like iphone 5s, then the walkea h500 will be note 3

Walkera G-2D Gimbal Troubleshooting

Many friends are using the walkera g-2d gimbal, and meet different problems in making it

work properly, most of the time it's just because they didn't set it up correctly, and

some of the rules are not included in instruction, here we have listed some of them:

1. If you do not need to use radio to control the gimbal, please set the SW switch to 0,

and adjust V1 V2 to 0 as well;

2. If the remote control can only control one channel of the gimbal(usually choose to

Control PIT-pitch), please switch SW to 1, and adjust the direction + of V1 or V2 to the

right angle, if you don't use the channel, please have V1 or V2 at 0. For example, if only

control PIT channel, just adjust certain angle in the direction of V1+,while the unused V2

must be set in 0;
3. If you want to use the PIT and ROLL channel, please switch SW to 1, adjust direction +

of V1,V2 to a certain angle, the larger the adjusted angle is, the wider the angle to the

steering of the gimbal and the angle will be increased to a max of 90 degrees accordingly.

http://www.oomodel.com/walkera-g2d-b...3-p-66523.html

This gimbal is a good choice for the x350 and x350 pro, you sometimes just need to give it

a bit more patience, and it's economical anyway!

Nine Eagles Galaxy Visitor 3 Review

Nine Eagles Galaxy Visitor 3 has many features as other similar UFO. A function return automated its starting point, so you can make it return whenever you want to avoid hitting something and damaging. To this is added a “Following ” mode: it is hoped that this is a function of monitoring the radio, which could be very interesting to shoot oneself in the practice of a sport. It keeps the characteristics of Nine Eagles galaxy visitor 2 , including size, weight, type of engine ( they are probably brushless) , battery, availability and still at the most favorable price.

http://www.oomodel.com/nine-eagles-g...r-p-66809.html

This model will be the hottest RC quad in this year. The most important is that the Nine Eagles Galaxy Visitor 3 works greater than you can believe,fast response,high speed,cool appearance!

Walkera QR X350 Pro Problems & Troubleshooting

The newest walkera phantom-like quadcopter, you know the walkera qr x350 pro http://www.oomodel.com/walkera-x350p...r-p-66617.html
performs really nice, we seen some friends flied them and found there are a few problems which actually are not problems that can’t be shoot, we will just list a few common ones:

The first one we noticed was that some friends forgot to connect the little signal wire which goes cross the skid, this way the quad will not bind to the radio whatever you do, the signal light will flash at the first moment, and then keep blind.

The second one was that you may use your radio for different models, and you were playing 3d lasttime, so the 3d stick was positioned at a totally wrong place for quadcopter, this will cause a crash actually an upside down, so don’t forget to place it at the right position.

The last but most important one is, many friends experienced a very annoying phenomenon,they have to power the quadcopter up everytime after they landed, they don’t understand what’s the problem is, we tested the same quadcopter and it did in a different way. Actually that’s because they landed too harshly, and the quadcopter take it as a crash and powered off automatically to protect the quadcopter. It’s very easy and might be hard for some others to handle.

We will update when we found more common problems…

The newly designed big size copter walkera qr x800 (http://www.oomodel.com/qr-x800-devo-...r-p-66700.html) is very much like the dji s800, in designing, also there are differences.

In apperance, as you can see they both have 6 frames, but the walkera qr x800 is foldable.

Battery, the x800 used 15000mah battery and it advertised the flight time will be up to 60 minutes, and s800 it said hover time 16 minutes, the s800 uses 10000mah battery.

Flying weight, the x800 is 3.5kg while the s800 is 4.3kg, got to say if the s800 use 15000mah battery, will the flight time be longer?

We do hope walkera or any other company will provide us with good copters with excellent performance and longer flight time and better not too costly

Walkera iLook FPV Camera Review

The Walkera iLook FPV Camera is a Built-in video transmitter and Fatshark goggles compatible,an all-in-one FPV camera.No extra video transmitter to install or extra battery to carry; this can translate to space saver, value for money.It’s available now, the retail price is 119usd, it is the same size as gopro 3, maybe that’s why walkera’s g-2d gimbal supports gopro 3 and ilook camera both.

http://www.oomodel.com/walkera-ilook...d-p-66531.html

It weighted 125g, and don’t need extra battery, you can connect it to the main battery of the quadcopter, and you can use Gear Switch from DEVO F7 and DEVO 10 to control the video directly.

DIY Align Trex 150 DFC

Align Trex 150 is surely another success for mini 3d helicopters,there are too many reviews about it already, and we just found a good save for money for this helicopter, not to diy the whole helicopter, but the servos, actually also some other parts.

The Align trex 150 that everybody knows, a little picture about it:



As we know,the ds150 servos has 6mm coreless motors,when we disassemble them,found the gears are completely compatible with the other ones that we have, this is a real great news, as these gears are really cheap.

The dji phantom has been a very successful fpv flyer during the last months, it performs really nice though priced not that nice

The other company walkera has offered us a qr x350 last year, that’s to be honest a good flyer,looks beautiful,very stable,economical, but the flight time is not too long. Now they just worked out the qr x350pro, it hasn’t been finally released yet, but it’s reported to be a time-lasting flyer, flight time will be up to 25 minutes lol

The main feature for the new version qr x350pro:
Latest GPS control system
