Since October 2013 I’ve been modifying a DJI Phantom quadcopter to try to achieve smooth and high quality aerial video as well as high quality aerial still images. I believe that I’ve got my Phantom performing the best one could possibly perform, and the video/photos the best I could get out of a GoPro 3 Black.
I found the GoPro to be very limited and the still image quality to really suck. I also found that despite the custom gains and different propellors, the Phantom gets thrown around in the wind due to its smaller size. Those factors made me decide I needed a larger and more stable platform so I could carry a larger, higher quality camera than a GoPro.
So I built a large hexacopter. Since then I’ve been doing the same tweaks to the hexa, trying to get all the little bugs worked out and achieve high quality aerial images. Then it dawned on me that my camera setup alone weighed more than my entire Phantom setup! Naturally the next step from there was to strap the Phantom to the bottom of the hexacopter as a small demonstration and different perspective. I used to worry about adding 20 grams to my Phantom for fear that it would fly poorly and I’d reduce my flight times even more.
From the video below, you can tell that 20 grams doesn’t mean too much now.
My new rig is still in the tweaking stage. During the build of the new rig, I managed to get my Phantom set to my satisfaction, and there are still situations where the bird will come in handy.
If you can understand 1/3 of the title of this post, you are a heli-geek. Yesterday I picked up the camera I will be using with my big hexactoper. The copter frame is a Tarot T960.
The Sony NEX-5T (a mirror-less high quality camera) is mounted to the frame via a auto-leveling device called a “gimbal.” That’s the Arris Zhaoyun (Chinese name of course).
I flew twice today. The first flight was pretty smooth and the jello effect (vibrating video) was hardly there. That’s what my current mode is, jello-reduction. Actually I should say jello-elimination.
This afternoon’s flight was more in focus as far as the camera went, but there was way too much jello. Post flight I looked at my remote and it looks like I had my gains turned down, which might have caused the jello. Gains are a fine-tuning setting for the motors. Also, the winds were up, which can also cause vibration issues.
In these photos you’ll notice that the camera is on one end, and the batteries on the other. I’m using the batteries as a counterweight.
The neighbors asked if I’d fly through their big fireworks show last night. It was a state holiday. Here’s the video highlights!
