APM Octocopter Build First Test Flight


This is the first test flight of our 1020-mm Octocopter build. It flew for 21 minutes on a charge. The batteries (2 x 5200 mAh 6S) are brand new, so maybe flight time will increase a little after the batteries are broken in a little.

Total weight (including batteries, but no camera/gimbal payload yet) is 5.0 kg.

Frame: Tarot T15
Flight Control: APM 2.6 with ArduCopter V3.2-rc14

1.3GHz FPV with High-Gain Helical Antenna

We usually look for a high or open spot to stand when flying long-range FPV to avoid our signal being attenuated by obstacles. This allows us several kilometers of range in the countryside without needing a directional (high gain) antenna. Sometimes you might not have such an ideal spot to fly from though, so it helps to use an antenna with a narrow beam to focus that weak signal.

We attached a handle, video receiver, and battery to the back of this Circular Wireless helical antenna so it could be held by one person and manually pointed toward the copter, while the other person flies FPV:

Circular Wireless Heliaxial 1.3GHz antenna with video receiver, battery, and handle mounted to back
On the video tx side we used the Circular Wireless Skew Planar Wheel. In our long-range mountain flying test, we started from a low point near the base of the valley, in a location with obstacles such as trees and buildings. We were still able to fly over 2.0 km away with a clear video signal.

Flew FPV in the mountains of Changhua to a peak 2.0 km away.


A drawback of the Heliaxial is that it is bulky, needs to be transported carefully to avoid breakage, and is probably too heavy to be mounted to most antenna trackers.

Fortunately, Circular Wireless has come out with a new Circularly Polarized 1.3GHz Patch Antenna that should be much more convenient. We plan to test it out on a flight soon!

1.4 km away, FPV Touch-and-Go behind Hill in Rain...


Flew in the rain 1.4 km away over a hill and did an FPV touch-and-go... followed by a 2-km SplineNav scenic flight back, and near electrocution of the copter (oops!)—and all of that in one single epic flight!

It's very hard to get good FPV range flying near the city: even with 1.3GHz and a high-gain (directional) antenna on the receiver, we only get about 1 km range hugging the terrain (much longer range is available flying high, but that doesn't make for as interesting videos).

So we headed out to the countryside to find radio quiet, and left the bulky high-gain antenna at home. With just a Circular Wireless SPW12 on both tx and rx, we were able to fly 1.4 km away, duck behind a hill, make a touch-and-go, and still get perfect video back the whole time.

Unfortunately the video still doesn't work well flying behind broad-leaf trees, even at much shorter ranges. Evergreen needle trees don't seem to be a problem though, perhaps due to their lower moisture content. We're now using a Lawmate 1000mA 1.3 GHz transmitter, which seems to work a lot better than the ReadyMadeRC tx, and is much lighter. We use RangeLink UHF for radio control, which seems to be pretty much invincible at any distance.

After doing the the touch-and-go on the grassy hill 1.4 km away, we engaged SplineNav and did a 2-km scenic flight back on autopilot. The rain was really picking up, and moisture got into the gimbal electronics, which made the GoPro twitch wildly from time to time, but otherwise the water didn't cause any harm.

Note the temple with the four characters 周氏宗祠 we fly over at 5:18. That's where my wife attended elementary school, long since abandoned and with trees growing up inside it.

The change in weather on the flight back seems to have affected the barometer, because where SplineNav was supposed to have gone under that last power line, it went straight through inside. Really amazing that it made it through that narrow gap with no damage other than a split prop tip. These high-voltage wires are bare of insulation and carrying the power for the whole village. Fortunately the electricity didn't arc across right through the aluminum arms of the copter!

First Flight with GoPro Hero 3+ Black


The colors are quite drab and dreary in the mountains over the winter, and filming with the GoPro Hero 3 Silver just makes the colors even more washed out. So we swapped it out for the GoPro Hero 3+ Black, hoping to get some more vibrant, true-to-life color in our videos.

This was literally our first ever flight with this brand-new GoPro, so I was flying conservatively, not wanting to make a mistake that would result in lens scratches on the new camera, or worse. So sorry I didn't get in closer to that massive ridge of granite going up the mountainside. Maybe next time!

The winds were very high through this valley today, the GoPro was in Narrow FOV mode (1080p @ 60 FPS), and the gimbal only stabilizes pitch and roll, so those factors combined to create a whole lot of shakiness in the yaw axis. So although we were very impressed by the image quality in Narrow mode, it looks like for future flights we'll want to stick to Medium FOV. That is until we can get a 3-axis gimbal for our GoPro.

The colors certainly came out a lot better than with the old GoPro, but since there was so much haze and leafless or frostbitten vegetation, the video still came out looking fairly dreary and lacking in color. Good thing Spring is almost here!
