By Terry Dunnon Sept. 24, 2014 at 12:33 a.m.Testing: Blade 350 QX2 AP Combo Quadcopter Review

I’ve been flying an original DJI Phantom quadrotor for almost two years. Even though it’s never given me an ounce of trouble, watching the super-stable video footage from quads equipped with camera gimbals convinced me that I needed an upgrade. Rather than add a gimbal to my Phantom, I decided to keep it as a sport flyer and add a new quad to my fleet. The new ship is a Blade 350QX2 AP Combo (~$900). Its features are similar to the Phantom 2 Vision + reviewed by Norm and Will, but there are a several differences. I will talk about those variances throughout this review.

The Blade 350QX series is not new. It was first released in the summer of 2013. Like the Phantom, the 350QX lineup has seen continuous improvements and added options. The AP Combo is the first 350QX equipped with a 2-axis gimbal and a camera. Blade brand quads and helicopters are quite popular, so you are likely to find kits and spare parts at your local hobby shop.

What’s In the Box

The AP Combo is a turnkey setup. It includes the factory-built quad, a Spektrum DX4 transmitter, the gimbal, a 3-cell 3000mAh LiPo battery, and an AC charger for the battery. The only thing I had to add was a micro-SD card for the GoPro-like CGO1 camera. I used a SanDisk 16GB class 10 card. The quad was 95% ready to fly when I opened the box. Even the props were installed (a full extra set is included as well).

The one required assembly step was to snap the gimbal unit into place on the bottom of the quad. If you’re not paying attention, it can be installed backwards. Trust me on that. If it doesn’t click into place easily, you’re doing it wrong. Retreat, regroup, and charge again. While I was working on the gimbal, I had the flight battery and camera charging on their respective chargers. The camera charges through a micro-USB cable (included).

The Blade 350QX2 AP Combo includes everything except a micro-SD card for the camera. Very little assembly is required.

Blade includes a Quick Start Guide to lead you through the necessary steps to get the quad in the air. It is easy to follow and understand. A full manual is available online as are numerous videos. I found the online videos especially helpful. Since I had watched several of them while the quad was being shipped, I already knew what to expect when I opened the box.

The battery connectors are the popular EC3 style that is included with most Blade products as well as the other house brands distributed by Horizon Hobby (E-flite, Parkzone, ECX, Losi, Vaterra, etc.). They work fine and there is no reason to replace them. However, all of my RC equipment is configured with Deans Ultra Plugs. For the sake of consistency, I swapped the EC3s on the 350QX2 for Deans.

What’s a Gimbal?

In a nut shell, a gimbal is a device that isolates the camera from pitching and rolling movements of the quad that is carrying it. For example: if the quad tilts to the right, the gimbal control board senses this motion and rotates the roll axis of the gimbal to keep the camera level. The end result is that the video footage is much smoother than what can usually be obtained without a gimbal. An added benefit is that the pilot can change the tilt angle of the camera in flight when using certain transmitters…more on that later.

The GB200 2-axis gimbal works well to smooth out the bumps of a typical quad flight. It comes with a mount for the included CGO1 camera (shown), but a GoPro Hero 3 mount is also available.

The gimbal included with the 350QX2 is the GB200, which is an optional add-on for other 350QX models. As I mentioned, the assembly snaps right into the preinstalled base unit on the quad. Also of interest is the flexible isolation mount used here. Four rubber boots separate the top and bottom halves of the mount. This setup prevents minor vibrations in the quad from reaching the camera and causing the dreaded jello distortion in videos. As included with the AP Combo, the GB200 has a mount for the CGO1 camera that is also a part of the package. Blade offers a GB200 camera mount intended for the GoPro Hero3 as well.

CGO1 Camera

The included CGO1 camera has a form factor very similar to a GoPro. Its outer dimensions are within a few millimeters of a GoPro Hero 2 on every axis. It is a snug press fit into the gimbal mount and there is also a small thumb screw to make sure things stay in place. What is most unique about the CGO1 is the mushroom-like Wi-Fi antenna that protrudes from the bottom of the camera.

The CGO1 is surrounded by other action cameras for size reference. The Wi-Fi antenna on the bottom of the CGO1 provided great downlink performance.

I couldn’t find any documentation showing the approximate range of the CGO1’s W-Fi signal, but I can say that it works much further away and with much less latency than the similar system on my Hero 3 Black. The Wi-Fi transmitter is automatically activated when you turn the camera on. Without the antenna attached, the Wi-Fi system could overheat and fail. Because of that risk, you have to be sure to have the antenna attached whenever the camera is turned on.

The Wi-Fi signal can be used to see a real-time view from the camera, start/stop recording, choose between still photo and video modes, and a few other items. The interface is made possible via the CGO1 app, which is available for Apple or Android devices. Be advised that the CGO1 transmits a 5.8GHz signal and may not be recognized by all phones and tablets. My older iPhone 4S was no-go, but an iPhone 5 and iPad Mini worked fine. In case you were wondering, the DX4 transmitter includes a clamp that can hold most smartphones.

The CGO1 shoots 1080p video at 30FPS--not exactly cutting edge, but it’s good enough for most situations. Still photos are 2MP resolution at 1920 x 1080 pixels.

Flight Modes

The 350QX has three flight modes that are selectable via a 3-position switch on the transmitter. Smart Mode in intended for rookie quad flyers. In this mode, all control inputs are relative to the position and orientation of the quad when it was armed. You set the 350QX2 on the ground with the nose facing away from you. Then, stand at least 16ft behind the quad. You are now standing inside the “SAFE Circle”, a zone that the quad will (ideally) not fly into.

This diagram from the 350QX2 manual shows how control inputs are translated when in SMART Mode. (Horizon Hobby image)

In Smart Mode, pushing the right stick forward will send the quad away from the SAFE Circle. It doesn’t matter which way the nose of the quad is pointing. Pulling back on the stick will bring the quad back towards the circle. Moving the right stick to the right or left will send the 350QX2 in a clockwise or counter-clockwise (respectively) circular path concentric to the SAFE Circle. Basically, Smart Mode relieves the pilot from having to maintain orientation of the quad. It will always respond the same no matter what its present orientation is.

Smart Mode relieves the pilot from having to maintain orientation of the quad. It will always respond the same no matter what its present orientation is.

Another facet of Smart Mode is that the 350QX2’s altitude is limited to 45 meters. The throttle input on the left stick is treated as a (somewhat) linear relationship to that altitude range. Full throttle takes you to 45 meters. Mid-throttle will park the quad at an intermediate altitude. Full down on the throttle stick will bring the quad in for a landing. It may sound like a loose relationship, but I found it very easy to manage in flight. Left/Right movements on the left stick will rotate the quad on the yaw axis.

AP (Aerial Photography) Mode removes the SAFE Circle and makes pitch and roll inputs relative to the quad’s present orientation. Pushing forward on the right stick will send the 350QX2 towards whatever the nose is pointing at. You must maintain visual orientation of the quad in order to competently command it where to go. AP Mode maintains the altitude-relative throttle positioning seen in Smart Mode.

Stability Mode is similar to AP Mode with a few differences. The control authority on every axis is much greater. You have the ability to tilt the quad faster and further in any direction. This lets you reach surprisingly fast flight speeds. This maneuverability stops short of aerobatic moves, however. No flips or rolls with this guy.

In Stability Mode, the position of the throttle stick is now relative to the available power output of the motors. All the way up is full throttle. All the way down is zilch. You must manage the throttle position to climb, descend, or maintain altitude.

In AP Mode and Stability Mode, control inputs on the right stick are more conventional. (Horizon Hobby image)

All three flight modes share a few different traits that most flyers will appreciate. Position Hold will keep the quad steady over the same small plot of ground as long as you make no inputs to the right stick. You can yaw or change the throttle while maintaining position. The Self-Leveling feature brings the 350QX2 back to level flight when you release the right stick.

Perhaps the most important feature is the Return To Home switch. When you flip this switch on the transmitter, the 350QX2 will begin heading back to the point where it was launched and automatically land itself. This is very handy for those times when you get too far away and lose orientation.

Flying the Blade 350QX2

The first thing I noticed at the flying field is that there is less than an inch of ground clearance when the Wi-Fi antenna is attached to the camera. You’ll have to operate from a relatively smooth surface to make sure the quad rests on its skids rather than the antenna.

I’ve found that my 350QX2 typically needs anywhere from 30 seconds to 1 minute to get a GPS lock. Smart Mode will not allow you to take off until you get the lock. You can depart in AP or Stability mode prior to GPS lock, but you forfeit the GPS-driven functions such as Position Hold and Return To Home. My personal policy is to stay on the ground until I get the lock, regardless of the mode I am using.

Overall flight performance of the 350QX2 is excellent. The different flight modes make it applicable for pilots with varying abilities.

Takeoffs with the 350QX2 are very smooth. With my Phantom, I often have to jump it into the air because it acts unstable within a foot or two of the ground. I don’t see that trait with this quad. It does fine with gentle, gradual liftoffs.

I’ve logged a lot of time flying the 350QX2 in Smart Mode. Quite frankly, it makes me feel dumb. Since I am already comfortable flying quads with vehicle-centric inputs, I have a tough time transposing to the “stick relativity” approach required for Smart Mode. It works exactly like the manual says it should. It just doesn’t respond the way my pre-programmed brain thinks it should. Then again, this mode is tailor-made for people with zero flight experience. I can see where it would be very intuitive for those folks.

Control response is brisk and the quad can really get truckin’! Low-level, full-speed passes down the runway are easy to perform and fun to watch.

If you plan to stay in the multi-rotor game for a while, you’re going to have to learn how to fly with vehicle-centric inputs sooner or later. My suggestion has always been to learn this technique with a RC simulator and/or a quality mini quad. I’ll concede that Smart Mode on the 350QX2 offers an alternate path to earn your wings. The upfront cost is lower than my suggested route since you are not investing in another quad or software. However, the potential cost of mistakes increases when using the larger, more expensive 350QX2 to train. Also consider that you will have to “unlearn” Smart Mode flying once you’re comfortable enough to make the switch to normal flying. You have options, so choose what suits you.

I find AP Mode comfortable and casual. Pitch, roll and yaw inputs respond the way I am used to. I don’t have any trouble adjusting to the altitude-relative throttle commands. Control response in this mode is smooth and subtle--just what you want when shooting video or photos.

Most of my flight time is spent in Stability Mode. I think that is mostly due to my comfort level with flying quads. Control response is brisk and the quad can really get truckin’! Low-level, full-speed passes down the runway are easy to perform and fun to watch. That’s the sort of flying that I’m saving my old Phantom for, but this quad is good at it too.

With the Blade 350QX2 parked next to my DJI Phantom, it is easy to see their similarities in size and layout.

I’m still working on my throttle management skills with the 350QX2 to avoid ballooning upwards as I level off at the end of a high speed pass. I’m actually thankful that the quad doesn’t handle this chore for me. If there were no challenge to flying it, I would become bored very quickly. For the same reason, it doesn’t concern me that the 350QX2 does not have programmable way points and full auto-pilot. It’s only fun for me if I’m (mostly) in command. I don’t mind being helped with features like attitude stabilization and GPS hold. However, if I can’t see the quad and tell it what to do, I figure that I might as well be on the simulator.

I’ve flown the 350QX2 in winds ranging from dead calm to a gusty 20mph. In all cases, I was very impressed by the position holding ability of the quad. I don’t know what the normal tolerance is for this GPS system, but I’ve never seen my quad drift more than a few feet in any direction. This compares favorably with my Phantom, which also drops anchor in the air very reliably. I have to admit that the 350QX2’s altitude-relative throttle inputs used in Smart and AP modes make it really easy to hold a steady altitude as well.

An asymmetric layout and different colored props on the 350QX2 provide some relief for the ever-present challenge of in-flight orientation.

The footprint of the 350QX2 is not quite symmetrical. This helps a little with in-flight orientation, but only a little. Different colored props front and rear help a little more, as do contrasting LEDs on the bottom side of the frame. Despite all of these features, sorting out which end is which can be somewhat challenging at times. That’s true in varying degrees for every with quad-rotor that I’ve ever flown.

In all the countless flights I’ve logged on my Phantom, I’ve never needed to use the “Go-Home” feature. Nor have I ever felt an urge to test the efficacy of Go-Home by turning off the transmitter (the method for engaging Go-Home on early Phantoms). There’s just something about killing the only link I have with the quad that I find hard to digest.

I have no reservations about engaging Return To Home (RTH) on the 350QX2. I just have to flip a switch on the transmitter…which never gets turned off. Each time that I have used RTH, the 350QX2 was returned to almost the exact spot from which it departed. Having this RTH safety net will give me confidence to send the 350QX2 out a little beyond my visual comfort zone...maybe.

I get flight times up to 13 minutes on the stock 3000mAh battery. Popular 2200mAh batteries will also fit, yet they provide shorter flight times.

With the stock 3000mAh battery I am able to get 13 minute flights with no reserve. This includes a mixture of hovering and horsing around in moderate wind. Your specific conditions and flying style may net different results. I have a handful of 3-cell 2200mAh batteries that also work well in the 350QX2 with 7-8 minute flight times.

Overall, I’m pleased with how the 350QX flies. I can’t find any legitimate gripes. I think that total rookies can use Smart Mode to get the 350QX2 in the air and steer it with relative confidence. Anyone with some mini quad or simulator experience should have no trouble flying in AP Mode. Stability Mode is lively enough to keep most experienced pilots happy while still being easy to fly. I’m not sure that you can ask much more of an off-the-shelf quad-rotor.

But What About the Gimbal And Camera?

Oh yeah, the gimbal was the whole point of getting this quad. I’m happy to say that it has been working flawlessly. From the factory, it is programed with a slight downward tilt to the camera. This has turned out to be a good setting for landscape shots which capture good proportions of ground and sky. If you prefer a different tilt angle, it can be set manually when the quad is armed.

The footage I’ve captured since using the gimbal has been a big improvement over what I’m used to with rigidly mounted cameras. As expected, the field of view remains much more consistent as the quad is bucked by the wind or direction changes. That’s exactly what I was looking for.

Here we see the quad lean into the wind while the gimbal keeps the camera steady.

My experience with the CGO1 camera has been a mixture of good and bad. I’ll start with the good. The Wi-Fi signal and interface with the phone app have worked better than I expected. I routinely get a link that is solid nearly as far away as I’m willing to fly the quad. With my setup, I usually see about one second of lag. I’d never be comfortable flying via that delayed view, but it is more than adequate for framing shots.

Unfortunately, I have not been impressed by the image quality of the video or photos from the camera. Colors tend to be somewhat washed out, even under blue skies with good lighting. The phone app has brightness and contrast settings, which can provide some relief. However, I have yet to see the vibrant colors that I was hoping for.

A more significant issue is that every shot is slightly out of focus. It seems that the lens is set to focus on close objects (< 1 foot), which doesn’t make much sense for a camera intended to shoot from the sky. Even if the focus on my unit was not a problem, the color rendering issue alone would have driven me to substitute the CGO1 with my Hero 3 Black. The CGO1 isn’t awful, but my GoPro is better. So, why not use it?

11This still photo from the CGO1 camera illustrates the soft focus and subdued colors that convinced me to install my trusty GoPro on the 350QX2.

The Hero 3 mounts for the GB200 are presently on backorder, but I hope to have one soon. In the meantime, I have been able to fit the smaller GoPro in the CGO1 mount. I just fill the empty space with foam rubber shims and retain the camera with a Velcro strap. It may not be the best configuration balance-wise (important with gimbals) but it has worked well so far.

This shot was taken with my GoPro Hero 3 Black strapped to the gimbal. It is easy to see the differences in clarity and color between the GoPro and CGO1.

There are two down sides to my camera mount hack. First, some of the buttons on the GoPro are obscured by the mount. This means that I have to remove the camera after each flight to turn off the Wi-Fi. Secondly, the Wi-Fi on my GoPro stinks in both range and latency. I’m sure that I will soon just turn off the Wi-Fi and eyeball my shots from the ground.

Many GoPro owners have reported that the Wi-Fi interferes with the GPS receiver on their quad (true of DJI and Blade quads). I guess I dodged that bullet because I have not seen any adverse effects with the Hero 3 in my quad. Flyers that have tackled this issue claim that a copper foil shield around the camera is an easy remedy.

Alternate Control

The included DX4 transmitter works great and I have no complaints about it. Owners of other Spektrum computer transmitters (DX7S, DX8, DX9, or DX18) can bind their radio to the 350QX2 and add real-time tilt control of the gimbal. It’s an easy process and there are how-to videos specific to each transmitter.

The Spektrum DX4 transmitter is a good, no-frills match for this quad. Note the phone clamp which makes it easy to view the camera’s video downlink. Also shown are spare props, the flight battery, and charger.

My last several flights with the 350QX2 have used my DX8 for control. A 3-position switch controls the gimbal. The uppermost position commands the gimbal to tilt the camera upwards, while the bottom position sends it in the other direction. The middle position tells it to stay put. In addition to gimbal tilt, I was also able to set-up dual rates. Translated, that means I can choose how sensitive I want the controls to be with the flip of a switch.

Some flyers appreciate the familiarity of using just one transmitter for every flying machine they own. That capability is one of the primary benefits of owning a computer radio. I can see where those guys would jump at the chance to link their radio to the 350QX2. I’m not one of those guys. I certainly don’t mind using my DX8 for this quad. I’m finding, however, that I rarely use the additional features that it affords. I almost never change the camera’s tilt angle and I like the stock sensitivity settings. I also like the idea of having a dedicated transmitter just for the 350QX2. As soon as I finish this review, I plan to relink the simple but capable DX4 to the quad.

Summary of Opinions

For the most part the Blade 350QX2 AP Combo provided everything that I was looking for in a new aerial video platform. It included all of the equipment I needed in a prebuilt, all-in-one package. It flies every bit as well as my DJI Phantom while also incorporating a “return home” feature that I’m not terrified to utilize. My only real disappointment regarded the lackluster performance of the CGO1 camera. That being said, I didn’t really need a camera to be included in the first place. Blade would have had to throw in a pretty spectacular camera to make me abandon my Hero 3. Perhaps they will offer a package with the gimbal and Hero 3 mount while omitting the CGO1.

Blade350 QX2 AP组合直升机测评回顾

特里Dunnon 2014年9月24日12:33 amTesting：刀片350 QX2 AP组合四轴飞行器评论
我一直在飞的原始DJI幻影quadrotor了近两年。尽管它从来没有给我麻烦盎司，看着从装有摄像云台四边形的超稳定录像说服了我，我需要升级。而不是一个万向节添加到我的幻影，我决定把它作为一项运动的传单，并添加一个新的四到我的舰队。新船是刀片350QX2 AP组合（?$ 900）。它的功能类似于幻影2远景+的规范和威尔审查，但也有一些差异。我就说说这些差异在整个审查。

该刀片350QX系列是不是新的。这是第一次在2013年像幽灵夏天释放，350QX阵容已经看到了不断改进和添加的选项。该AP组合是配备了2轴万向架和一个照相机的第一350QX。刀片品牌四边形和直升机都相当受欢迎，所以你可能会发现套件和零部件在当地的爱好店。
是什么在箱
美联社组合是一个交钥匙的设置。它包括工厂制造四，一个SPEKTRUM DX4发射器，万向节，3芯3000mAh的锂聚合物电池和AC充电器为电池充电。我唯一不得不添加是一个micro-SD卡为GOPRO般CGO1相机。我用SanDisk的16GB类10卡。四是95％箭在弦上，当我打开盒子。连道具都安装（完整额外的设置也包括在内）。

一个必需组装步骤是万向架单元卡入到位于四元的底部。如果你没有注意，也可以反向安装。相信我这一点。如果没有豁然开朗容易，你这样做是错误的。撤退，重新集结，并再次充电。当我工作的万向节，我有飞行电池和相机充电在各自的充电器。通过一个微型USB连接线将相机费用（含税）。
该刀片350QX2 AP组合包括一切，除了一个micro-SD卡的相机。极少装配是必需的。
刀片包括一个快速入门指南，以引导您完成必要的步骤来获得在空气中四。这是很容易跟踪和了解。全手动联机可作为众多视频。我发现在线视频特别有用。既然我已经看了其中几个，而四是被运，我已经知道会发生什么事情，当我打开盒子。

电池连接器附带大多数刀片产品以及由地平线业余爱好（E-FLITE，Parkzone，ECX，Losi，Vaterra等）分布在其他自有品牌流行EC3风格。他们的工作很好，没有任何理由，以取代他们。然而，所有的我的RC设备配置有院长超插头。为了统一起见，我换的350QX2为院长的EC3s。
什么是万向节？
在坚果壳，万向节是隔离的相机俯仰和滚动是背着它的四核的移动设备。例如：如果四倾斜向右侧，万向节控制板检测到这种运动和旋转的万向节的侧倾轴保持相机水平。最终的结果是，视频画面是要比通过通常在没有常平架来获得更平滑。一个附加的好处是，飞行员可以使用某些发射机...稍后更多时改变飞行摄像机的倾斜角度。
该GB200 2轴万向节能很好地理顺典型的四飞行的颠簸。它配备了一个安装了包括CGO1相机（如图所示），但GOPRO英雄3坐骑也可以。
附带350QX2常平架是GB200，这是一个可选的附加的其它350QX机型。正如我所说，组装卡正确插入四预装的基本单元。同样有趣的是灵活的隔离安装在这里使用。四胶靴分开安装的上半部和下半部。这种设置可以防止轻微振动四到达摄像头，并造成可怕的果冻扭曲视频。作为包含与AP组合中，GB200具有安装为CGO1相机，这也是包的一部分。刀片提供GB200摄像机安装旨在用于GOPRO Hero3为好。
CGO1相机
附带的CGO1照相机具有一个外形非常类似于GOPRO。其外部尺寸是内于每一个轴GOPRO英雄2几毫米。这是一个温暖的压入万向支架和也有一个小的拇指螺丝，以确保事情留在原地。什么是最独特的CGO1是蘑菇状的Wi-Fi天线伸出从相机的底部。
该CGO1是由其他行动相机大小的参考包围。在Wi-Fi天线上CGO1的底部提供了极大的下行链路的性能。
我找不到显示CGO1的W-Fi信号的大致范围内的任何文件，但我可以说，它的工作原理进一步去和比同类系统延迟更少我的英雄3黑色。当您打开相机的无线网络发射器被自动激活。如果没有天线连接的Wi-Fi系统可能会过热并失败。正因为如此危险，你必须确保无论何时打开相机时已经天线连接。

在Wi-Fi信号，可用于看到摄像机实时视图，开始/停止录制，静态照片和视频模式之间进行选择，和一些其他物品。该接口是通过CGO1的应用程序，它可用于Apple或Android设备成为可能。被告知，该CGO1发送一个5.8GHz的信号，可能不是所有的手机和平板电脑的认可。我的旧款iPhone 4S是不走的，但在iPhone 5和iPad迷你的罚款。如果您想知道，在DX4发射器包括一个夹具，可容纳大多数智能手机。

该CGO1拍摄1080p视频以30fps - 不完全是最先进的，但它在大多数情况下已经足够了。不过照片是在1920×1080像素200万像素的分辨率。
飞行模式
该350QX有三个飞行模式，可通过在发射器3位开关选择。智能模式供菜鸟四传单。在这种模式下，所有的控制输入是相对于当它被装备四边形的位置和方向。您可以设置在地面上的350QX2用鼻子面临远离你。然后，站在至少16英尺四落后。你现在站在“安全圈”，使四会（理想）不飞入区内。
这从350QX2手动图显示控制输入是如何在智能模式下，当翻译。 （地平线业余爱好图片）
在智能模式下，按下右摇杆向前将从外管局圈送四了。不要紧哪种方式四的鼻子指向。向后拉的棒将带来四背面朝向圆。移动右摇杆向右或向左将派350QX2顺时针或逆时针（分别）环形路同心向国家外汇管理局圈。基本上，智能模式减轻了飞行员不必维持四的方向。它总是不管其目前的定位是响应相同。
智能模式不必维持四方位减轻了飞行员。它总是不管其目前的定位是响应相同。
智能模式的另一面是，350QX2的海拔高度限制在45米。在左摇杆的油门输入被视为该高度范围内的（有点）的线性关系。全油门带你到45米。中秋节油门将车停在四在中间高度。在油门全部下跌将带来四为着陆。这听起来像一个松散的关系，但我发现它非常易于管理的航班。在左摇杆左/右移动将旋转偏航轴四。

AP（空中摄影）模式消除了安全圈，使相对于四公司目前的方向俯仰和滚动投入。推进在右摇杆将发送350QX2对任何机头指向。你必须保持四的视觉定位，以胜任命令它去哪里。 AP模式保持高度相对节气门位置出现在智能模式。

稳定模式，类似于AP模式有一些不同。在每个轴的控制授权大得多。你必须倾斜四更快，进一步在任何方向的能力。这可以让你达到惊人速度飞行速度。然而，这种机动性停止短的特技飞行动作。没有翻转或辊，这个家伙。

在稳定模式下，油门杆的位置现在是相对于可用功率输出的电动机。一路上涨是全油门。一路下来就是齐尔希。你必须管理节气门位置攀登，下降，或保持高度。
在AP模式和稳定模式，在右摇杆控制输入更传统。 （地平线业余爱好图片）
所有这三个飞行模式分享几个不同的特质，大多数传单会升值。定位保持将保持稳定的四在同一小块地，只要你不作任何输入的右摇杆。您可以偏转或改变油门，同时保持位置。自流平功能带来的350QX2恢复水平飞行，当你松开右摇杆。

也许最重要的特点是回归到原点开关。当你翻转的发射器这个开关，350QX2将开始回笼，它被启动，自动土地本身的地步。这是非常方便的那些时候，你离得太远而失去方向。
飞刀片350QX2
我注意到在飞行场的第一件事是，当Wi-Fi天线被安装到相机有小于离地高度英寸。你必须从一个相对平滑的表面工作，以确保四取决于它垫木，而不是天线。

我发现我的350QX2通常需要的任何地方从30秒到1分钟获得GPS锁。智能模式会不会让你起飞，直到你得到的锁。您可以在AP或之前GPS锁定稳定模式离开，但是你放弃了GPS驱动的功能，如位置保存并返回到首页。我个人的政策是留在地面上，直到我得到的锁，无论我使用的模式。
在350QX2的整体飞行性能非常出色。在不同的飞行模式，使其适用于飞行员有不同的能力。
起飞与350QX2都非常顺利。用我的幻影，我经常要跳向空中，因为它的作用在地面的两英尺内的不稳定。我没有看到该性状与此四。它做精温和，渐进的liftoffs。

我已经记录了大量的时间飞在智能模式下350QX2。坦率地说，这让我感到愚蠢。既然我已经飞行的舒适与四边形汽车为中心的投入，我有一个艰难的时间置换成所需要的智能模式“大棒相对论”的做法。它的工作原理完全一样手册说应该。它只是不响应我的预编程的大脑认为它应该的方式。然后，这种模式是专为人们零的飞行体验。我能看到那将是非常直观的那些人。
控制反应活跃，四能真正得到truckin'！低级，全速向下传递的跑道很容易执行，并让人赏心悦目。
如果您打算留在飞行器游戏一段时间，你将不得不学习如何与汽车为中心的投入早晚飞行。我的建议一直是学习这种技术与RC模拟器和/或质量小四。我承认，智能模式的350QX2提供了另一种路径来赚取你的翅膀。前期成本比我建议的路线下，因为你没有投资于其它四或软件。然而，错误的潜在成本使用更大，更贵350QX2培养时增加。同时认为，你将不得不“忘却”智能模式飞行，一旦你舒适，足以使开关正常飞行。你有选择，那么选择什么适合你。

我发现AP模式舒适和轻松。俯仰，滚转和偏航输入的响应，我习惯的方式。我没有任何麻烦调整到海拔相对节流阀命令。在此模式下控制响应平滑和微妙的 - 你想拍摄视频或照片时，正是。

我大部分的飞行时间都花在稳定模式。我认为这主要是由于我的伴飞四边形的舒适程度。控制反应活跃，四能真正得到truckin'！低级，全速向下传递的跑道很容易执行，并让人赏心悦目。这是飞说我救了我的老幻影的那种，但是这四擅长这一点。
与刀片350QX2停在旁边的我DJI幻影，很容易看到他们在大小和布局相似。
我还在我的油门管理技能与350QX2避免膨胀向上，因为我稳定下来在高速通到底。我其实感到欣慰的是四不处理这个苦差事我。如果没有挑战，以飞翔的话，我会变得无聊得非常快。出于同样的原因，它不关心我，350QX2不具有可编程的方式分全自动驾驶。这是唯一的乐趣了我，如果我（主要）的命令。我不介意被帮助了像姿态稳定和GPS保持功能。不过，如果我不能看到四，并告诉它做什么，我想，我还不如在模拟器上。

我已经飞行在风从风平浪静到风口20英里每小时的350QX2。在任何情况下，我是用四线的位置保持能力非常深刻的印象。我不知道正常的宽容就是对这种GPS系统，但我从来没有见过我的四比几只脚在任意方向漂移了。这与我的幻影，这也下降锚在空气中很可靠相比，毫不逊色。我不得不承认，在智能和AP模式中使用的350QX2的海拔相对油门输入使它很容易保持一个稳定的高度为好。
非对称布局和不同颜色的道具在350QX2对飞行方向始终存在的挑战提供一些救济。
该350QX2的足迹是不太对称的。这有助于有点与飞行中的方向，但只有一点点。不同颜色的道具前部和后部的帮助多一点，因为这样做对比发光二极管在所述框架的底侧。尽管所有这些功能，整理出这到底是哪个有时可能有点挑战性。这在不同程度上为每一位与四旋翼，我已经坐过如此。

在所有的无数的航班，我登录我的幻影，我从来没有需要使用“转到家”的功能。我也没有以往任何时候都感到一种冲动通过关闭发射机（方法从事早期鬼怪的Go-Home）以测试的Go-家的疗效。这里还有一些关于杀害我有，我觉得难以消化四的唯一纽带。

我对此毫无保留搞返回首页（RTH）在350QX2。我只需要翻转的发射器......永远也不会被关闭的开关。我已经使用RTH每一次，350QX2返回到几乎从它出发的确切位置。有了这个RTH安全网会给我信心送350QX2出一点超出了我的视觉舒适区......也许。
我得到的飞行时间长达13分钟的股票3000mAh的电池。流行的2200mAh电池也适合，但他们提供更短的飞行时间。
随着股市3000mAh的电池，我能得到没有储备13分钟航班。这包括盘旋和在温和风胡闹的混合物。您的具体情况和飞行风格可能净赚不同的结果。我有一个极少数的3芯2200mAh电池，在7-8分钟的飞行时间的350QX2也工作得很好。

总体来说，我很高兴与350QX过得如何。我找不到任何合法的抱怨。我认为，总的新秀可以使用智能模式，以获得350QX2在空气中相对自信驾驭它。任何人只要有一些小型的四或模拟器的经验应该没有问题，飞在AP模式。稳定模式是不够活泼，以保持最有经验的飞行员幸福的同时仍然容易上手。我不知道，你可以问更多的场外现货四转子。
但对于万向和摄像头？
噢，万向节是得到这四整点。我很高兴地说，它已经可以完美地运行。从工厂，它是程序性有轻微向下倾斜相机。这已被证明是一个很好的设置风景拍摄，捕获地面和天空良好的比例。如果你喜欢一个不同的倾斜角度，可以手动设置时四布防。

因为使用了万向，我拍摄的镜头是一个很大的改进，我已经习惯了用刚性安装摄像头。正如预期的那样，视场保持更加一致的四元是由风或方向变化顶住。这正是我一直在寻找。
在这里，我们看到了四精益进风，而万向保持相机稳定。
我与CGO1相机的经历是好的和坏的混合物。我先说好。在Wi-Fi信号和接口与手机应用程序工作过，比我预想的要好。我经常收到一个链接，是实心的近远，我愿意飞四。随着我的设置，我通常看到约一秒钟滞后。我从来没有舒服经由延迟观点飞行，但它是绰绰有余取景构图。

不幸的是，我并没有留下深刻印象来自摄像机的视频或照片的图像质量。颜色往往是有点冲了出去，即使在蔚蓝的天空有良好的照明。手机应用程序有亮度和对比度设置，它可以提供一些救济。但是，我还没有看到鲜艳的色彩是我所期待的。

更显著的问题是，每一个镜头稍微失焦。看来，镜头设置专注于近处的物体（<1英尺），这没有多大意义的相机打算从空中拍摄。即使专注于我的单位是不是有问题，单独显色问题将驱使我去替代CGO1与我的英雄3黑色。该CGO1是不可怕的，但我GOPRO更好。那么，为什么不使用它呢？
11本静态照片从相机CGO1说明了柔焦和柔和的色彩，说服我的350QX2安装我信赖的GOPRO。
英雄3挂载为GB200是目前的缺货，但我希望很快有一个。在此期间，我已经能够适应更小的GOPRO在CGO1坐骑。我只是填充泡沫橡胶垫片的空白，并保留了摄像头，尼龙带。它可能不是最好的配置均衡，明智的（与万向支架很重要），但它一直很好，到目前为止。
这个镜头是采取我的GOPRO英雄3黑色绑在万向节。很容易看到在GOPRO和CGO1之间的清晰度和颜色的差异。
有两降双方到我的摄像机安装黑客。首先，一些上GOPRO按钮被安装遮蔽。这意味着我必须在每次飞行后，取出相机关闭无线网络。其次，我GOPRO了Wi-Fi很臭的距离和延迟。我敢肯定，我会尽快只是关闭了Wi-Fi和地面眼球我的镜头。

许多GOPRO车主报告说，在Wi-Fi干扰了他们的四核GPS接收机（DJI的和刀片四边形真）。我想我躲过了子弹，因为我还没有看到在我四英雄3任何不利影响。已经解决了这个问题，传单宣称相机周围的铜箔屏蔽是一个简单的补救措施。
备用控制
所包含的DX4发射的伟大工程，我没有抱怨它。的其他SPEKTRUM计算机发射机（DX7S，DX8，DX9，或DX18）拥有者可以自己无线电绑定到350QX2并添加万向节的实时倾斜控制。这是一个简单的过程，有如何做具体到每个发射器的视频。
该SPEKTRUM DX4发射器是一个很好的，没有廉价的比赛为这个四。请注意，手机夹，这使得它可以方便地查看相机的视频下行链路。还示出了备用的道具的飞行电池，和充电器。
我与350QX2最后几个航班都用我的DX8进行控制。 3位开关控制的万向节。最上面的位置指令万向架倾斜相机向上，而底部位置发送它在另一个方向。中间位置告诉它留在原地。除了万向节倾斜，我也能够建立双重比率。翻译，这意味着我可以选择我是多么的敏感希望控制要与交换机的翻转。

一些传单欣赏只使用一个发射器，用于他们自己的每一种飞行机器的熟悉程度。这种能力是拥有一台电脑无线的主要优点之一。我能看到那些家伙会很高兴有机会到他们的无线链接到350QX2。我不是那些家伙之一。我当然不介意用我的DX8此四。然而，我发现，我很少使用它提供的附加功能。我几乎从来没有改变相机的倾斜角度，我喜欢股票灵敏度设置。我也喜欢有一个专门的发射器只是为350QX2的想法。当我写完这篇评论中，我打算重新链接简单，但能够DX4到四。
观点摘要
在大多数情况下的刀片350QX2 AP组合，只要我一直在寻找一个新的空中视频平台的一切。它包含了所有我需要在一个预先构建的设备，所有功能于一身的包。它飞的每一位和我DJI幻影同时还集成了，我不是害怕利用“回国”的功能。我唯一真正的失望都把CGO1相机的表现乏善可陈。话虽这么说，我并不真的需要一个摄像头被包含在首位。刀片将不得不扔在一个非常壮观的摄像头，使我放弃我的英雄3.也许他们将提供包万向节，虽然省略了CGO1英雄3架。
