繼Hubsan的H107C, H107D, H111以及Syma X5C後,DM007 Spy成為了大男孩的最新小型航拍機,這個全名為DAMING的品牌,為這隻小型航拍機注入了幾個頗為獨特的功能,而這些功能就吸引了大男孩的興趣了。
到底如何操控一隻四軸飛行器呢,大男孩就以DM 007 Spy示範一下啦。
DM007 Spy is my 5th toy grade minidrone after Hubsan H107C, H107D, H111 & Syma X5C. The brand name DM stands for Daming which is a very common Chinese first name. Even though it's fundamentally a me2 toy quad, it does have some unique features that interests me. Before showing those features, let's have a look on its indoor performance and a short how-to-operate video.


在外觀上來看,DM007 Spy最獨特的設計就是其細小的螺旋槳,尺寸就跟Hubsan X4系列的掌上四軸差不多。以它的軸距其實可以安裝更大的螺旋槳,提供更大的上升動力,但廠方並沒有這樣做,反而用上細小的螺旋槳,但這就是它能吸引大男孩的原因...The most significant difference between DM007 Spy and other similar size quad is the size of the propellers. The motor distance is the same as Syma X5C but it doesn't have the same prop size as it. Instead they are similar size to Hubsan X4, which are really small. One will easily think it will loss a lot of lifting power.   But why do they do it?

因為它夠細!有玩過玩具四軸機的朋友就會知道玩具機的螺旋槳一般都沒有快拆設計,即是說要拆漿就要得先鬆螺絲,很麻煩,而且螺絲很容易丟失,所以我們一般都不會拆漿,整隻攜帶。但DM007 Spy因為用上細小的螺旋槳,就算裝好防撞圈都比Syma X5C細小,更加方便攜帶。Because of the small prop size the quad is also very small. If you have experience in playing toy grade quad, you will know usually its props doesn't have quick release function. That means you need to remove some screws in order to remove the props. And we usually don't do that because it is troublesome and those screws will easily get lost. For DM007 Spy it is not a problem at all. Even though with the prop guards on, it is still considerably smaller than Syma X5C. It may sounds silly to save a bit of dimension. But for me who live in a small city like Hong Kong and would like to bring a miniquad always with me during the day, it does matter.


防撞圈包著馬達,馬達尺寸好像比其他相同軸距的玩具四軸為大...By default the prop guards were installed. It protects both the props and the motors. It seems the size of the motors are slightly bigger than other quad in the same class.

把螺旋槳拔起,鬆開一根螺絲後就可以把防撞圈拆除。Unplug the prop and remove one screw to remove the prop guard.

馬達的真身,真的比一般同軸距的四軸為大,相信是要彌補因為使用細小螺旋槳而失去的上升力。這個馬達的外觀好像一個迷你的四驅車馬達!The motor is really bigger than those in the same class. I have no way to tell its spin speed but I assume it is more powerful than those using in Syma X5C. So it might compensate a bit of the lifting power lost due to small prop size.

拆掉防撞圈後的DM007 Spy真的比Syma X5C細小得多。After you remove its prop guards it become not much bigger than a Hubsan X4. Syma X5C suddenly become a big brother.

要推動這個比較大的馬達,DM007 Spy用上了7.4v 2S 380mah的Lipo電池,但就未有提供平衡充電線,這是否意味著兩塊電池有機會出現電壓不平衡的情況呢?不過別想太多了,根據大男孩經驗,玩具級四軸的電池壽命遠比正常電池為低,一樣很快要更換的。May be because of the bigger motors DM007 Spy consume more power from a 7.4v 2S 380mah Lipo battery. The battery doesn't come with any parallel charge cable. Not sure if it will affect the voltage balance between cells. Anyway the battery of toy grade quad will easily die so replacement is always needed.

電池蓋在機身底部,連接線是跟Hubsan X4及Syma X5C相同的小白頭插頭。電源線一經連接,DM007 Spy就會被啟動,機身前後的LED燈就會亮起。飛行時間就大概有5-6分鐘左右。電池蓋可以拆除,方便日後掛上不同的小型相機。The battery is inserted from the bottom. The plug type is the same one as Hubsan X4 and X5C. The quad will be turned on once the battery cable is connected. Flight time is around 5-6mins per battery. Battery door can be completely removed so it should be able to carry a 808 #16 keychain camera.

大男孩手上的DM007 Spy是帶相機的版本,屬於HD質數的小型相機,能拍攝解釋度為1280x720的AVI格式影片或象素為1280x720的照片,兩者都能透過遙控器進行遙控拍攝。The one on my hand is with camera version. Camera itself is HD quality meaning it records 1280x720 pixels videos and photos. Shooting can be remotely triggered by the transmitter.

照片質數就平平無奇,跟其他玩具四軸航拍器差不多,都是舊webcam質數。Picture quality of the photo is average. Similar to other toy grade quad the images look like taken by a webcam.

顏色有一點藍,比例比拉闊了,其他還可以。White balance is ok but a bit to the blue side. The photo is stretched to 16:9 from a 4:3 ratio. You can easily change it back by any photo editing software.

影片的質素其實就不錯,但是不夠鏡頭不夠廣角。Video quality is not bad at all. It will be better if the lens is wider. Have a look at the raw footages from it.

DM007 Spy的遙控器外觀及功能都差不多跟Syma X5C的遙控器一模一樣,連binding的方法都完全相同,都是打開兩邊的電源後,把油門桿推到最高位置,然後返回最低,聽到beep一聲代表連接成功。遙控器頂部左邊的按鈕為速度模式選擇,有快慢兩個模式選擇,右手邊的按鈕為翻滾按鈕,按下按鈕,再把任何一支操控桿推到最盡,它就會向那個方向翻滾。The transmitter of DM007 Spy looks almost the same as the one of Syma X5C. They also share the same binding and arming procedure. After turn on the quad, turn on the transmitter will bind to the quad. Push the throttle stick to the top then to the bottom will arm the motors. Arming will be confirmed by hearing a beep sound. There are 2 buttons on the top of the transmitter. The left one toggles between 2 speed modes, High or Low. The right one trigger the flip. By pressing it together with the right stick (mode 2) will perform flip.

遙控器上的LED顯示屏能顯示四軸機的狀況。屏幕右上角的L字或H字就分別代表了Low speed及High speed模式。The LED screen on the transmitter tells you the status of the quad. The L or H letter on the top right corner represents which speed mode the quad is on. L means low and H means high.

把DM007 Spy帶到戶外飛行,發覺其飛行穩定性很高,從拍攝出來的影片可以看得出機身震動很少。Low speed模式機身傾斜幅度低,非常合適於微風的日子進行航拍,但遇上大風一點的情況,最好還是轉到High speed模式飛行。由於機底沒有燈,飛行時比較難辨別前後,另外大男孩發現當它意外墜落地面時,其螺旋槳比較容易飛脫,這都是DM007 Spy的一些缺點。It's time to bring it outside for an outdoor flight. It is a stable flyer and record quite stable video footages. The low speed mode limits the pitch and roll angles that makes it suitable for taking aerial video. But it doesn't like wind at all. In case of strong wind switching to H mode isn't a bad idea. Downside of this quad: lack of LED light on the bottom makes you difficult to identify its flying direction. Since the quad is just pressed to the motor pin so sometimes it loose during crash.

總括來說DM007 Spy的飛行特性非常似Syma X5C,但就細小的多,外觀也好看多了。等香港天氣好一點,再用它拍多一點航拍影片。有興趣購買DM007 Spy的朋友,可以到Gearbest選購:
To conclude DM007 Spy fly like Syma X5C. If you are looking for a stable video platform it is not a bad choice next to X5C, especially if you want a smaller quad to be easily carried. I can't wait to shoot more videos with it when the weather of Hong Kong get better. If you like this quad they are available in Gearbest:
