Before Aug I had no chance to fly the DJI F450, the first two weeks of august were not ok for flying, so I started in the middle of August.
18-aug-2016: Checked the batteries, compass and IMU calibrated, and it runs again.
On 24-aug and 25-aug I had two more flights, one on the beach and one on the moor. The “Maasvlakte video” dates from 24-aug.
The flight on 25-aug-2016 “Loon op Zand” had two hard landings because of battery capacity problems, either the low voltage level is too high, either I should charge the batteries differently, namely not at 1C but at a 1/2 or less at done prior to 25-aug-2016.
31-aug-2016: “Sunset at Oostvoorne” all went fine on this evening, except for taking off in the last run where I accidentally put it in manual mode, drone drifts in ATT mode at take-off while it is too close, you want to flip to GPS mode, but you execute MANUAL mode and then it is too late. This quadcopter is really sensitive in MANUAL mode.
11-sep-2016 “A few hours on the beach”: Fixed the gimbal (the Feiyu is easy to repair), one cable was disconnected during the last crash, replace a propellor, wait for a wind free day and off we go (10-sep had too much wind, so I took the kite up).
14-Sep-2016: “Beach Oostvoorne” went further south in the hope the beach was empty on a Wednesday afternoon, it pretty much was. Flew over the dunes and returned over the shorelines. Wind up to 4 m/s from the south, temperature 32C.
Trust me, I’m an engineer was the previous title of this blog
Yesterday evening I worked with KE1Y on 7147 kHz 23:51 UTC, PJ4DX on 14213 kHz 22:55 UTC, F5BZB 7180 kHz 6:06 UTC and F8NAN 7149 kHz 5:49 UTC. On 40m I had more luck than on 20m. Had some e-mail exchange with R0AU about WSPR details. I asked Vadim whether he had the possibility to determine a direction of my 200 mW WSPR signal at 14097.125 kHz. He has a moxon antenna pointing to the west, so he was not receiving the signal via a long path. Later I received some nice quadcopter footage from the Krasnoyarsk sea:
Looks like a nice area with lakes, forests and fields, there is certainly space enough for HF antenna’s there. Looking for a websdr in the Krasnoyarsk area, they got it.
Although most people probably call it the D-word hobbyists don’t, because they don’t want to be associated with the D-word. I made one last summer, it takes a couple of days and gradually you get something you like, and what you’re able to control safely.
And finally, add the gimbal, what is a gimbal? It keeps the camera straight, stable, whatever. And you add of course controls on the transmitter to adjust the gimbal remotely. Add a video transmitter, and you’re done.
Next, wait for a nice day without too much wind (4 m/s is really a lot already, maybe 8 m/s is the limit) go in the field and enjoy, just browse the internet to find out what’s possible, and also, where it is allowed. Here are some of the videos that I made:
