A really interesting tractor

I browsed the Internet and was attracted by a tractor! It sounds amazing! That's it,called Wltoys P949 Monster Tractor:

Don't you think it is cute and fresh? Obviously, it doesn't look smart like other cars. On the contrary, this one tends to be cumbersome. Let's have a first look at this gadget through the unboxing video below:

After watching the video, the four huge wheels convinced me that it must be a heavy tractor, which makes me more curious about how it run! Luckily, I found the video!

Wow!This Wltoys P949 breaks my regular imagination to a tractor. I never thought it can be so fast!Just viewed from the video, it is cool especially when group running.Does it arouse your interest to play it?

It seems that it is a nice quad!Compact size with 2.0 MP HD camera.

But I am curios whether it it hard to learn fly for a beginner.

I searched online and found its specifications, hope it is helpful.

the shooting effect of Inspire 1 Pro X5

Summery:
1, X5 adopts the original 15mm fixed-focus lens of DJI, which records distortionless images. But we’ll feel the angle is not broad enough. Well, every coin has two sides. The good is that you can get strong movie sense, suitable for little scene. While for larger scene, you need to fly higher and farther.
2, the lens of X5 is replaceable. So if you want to have large scene shooting, it is suggested to mount a OLYMPUS 12mm fixed- focus lens.
3, carrying a X5 makes Inspire 1 heavier. Although it shorten four-minute flight time, that doesn’t have too bad impact on photographing.
4.Is 4K image useful for ordinary players? Well, that depends on how you play in the latter. For example, if we make digital zoom, as 4K provides enough pixel, even we change to 1080p, we can still have fourfold zoom effect.
5.We can see the images shot when falling dramatically are still stable, which means that X5 is reliable in the aspect of stability.

DYS Smart Gopro Gimbal review: good performance, easy to calibrate

Before starting my review of DYS Smart Gopro Gimbal, i would like to ask those who have using experiences with Tarot T-2D GoPro Gimbal, whether it is a really great gimbal. Before i bought this Smart, my friend suggested me to buy the Tarot one, but i was afraid it is not stable enough as it is 2-axis. But no matter whether i missed a good gimbal or not, all i want to say is that this DYS Smart Gopro Gimbal is also wonderful.

In my opinion, for video work, a 3 axis is essential, that’s why i didn’t choose the Tarot T-2D. Pretty good build quality and a quality controller (not like the really cheap ones) make me really impress with DYS Smart Gopro Gimbal. It is introduced to be plug and play, but for me, it didn’t work out of the box. But with some patience and a lot of forum reading, i got it up and running including RC tilt control. And with a bit of tuning, it offers great performance and stability, and does all i expect.

Everything is is aluminum and carbon fiber, DYS Smart Gopro Gimbal weighs about 230g. I’ve simply attached to my Phantom, connected battery and two channels on receiver and away you go. Due to your aircraft thrust, it may needs some PID settings and absolutely loosing power if your batteries voltage is lower than 12V. I think the best setup scenario is 4S setup and using BEC for gimbal at 12V all the time.

Software of DYS Smart Gopro Gimbal can be downloaded from the Internet, and it is accurate and comprehensive. At the beginning, the YAW was out slightly( means the camera pointed left a little), but after downloading the GUI, it was simple to tweak to straighten it.

What’s more, it is no problem to connect a AV plug to send the image on FPV, there is enough place. In one word, DYS Smart Gopro Gimbal is a fine product.
