First FPV flight of my new copter which I built. Cleanflight settings are all default, except a bit higher pitch, roll and yaw rate and custom switches to enable the blackbox recording and the beeper (as a lost copter function). I tested the blackbox feature with the on-board dataflash and used the blackbox-tools to create an overlay. Besides the stick positions and the PID values (which I have to tune next), it is nice to see the battery current and used energy. But I need to add a low-pass filter to the output of the current sensor, it is too noisy.

There is a rail at Rheinauhafen, with lights in regular distances. At each light are big spider webs and spiders.

Testing a Brio Battery Powered Engine, Art# 33595, with the Batteroo sleeve. The tracks were glued with double-sided tape to the pertinax board, for same test conditions. Result: without the sleeve it ran for 127 minutes, with the sleeves for 59 minutes and using the sleeves on the dead battery of the first test, it ran for 4 minutes. The video shows all 3 tests in one shot, no editing, only time lapse when it is not interesting. In the small overlay at bottom right in the first half of the video, you can see the test with the sleeve, to compare it without the sleeve.
At 6:28 you can see in the overlay how it dies with the sleeve, while it is still running without the sleeve at this time, and after this you can see the 4 minute run, and at the end of the video at 24:20. At 18:03 the original battery is removed from the toy and a new battery with the Batteroo sleeve attached is inserted and the test is repeated. You can also see that the train runs faster without the sleeve.
Conclusion: The Batteroo sleeve has no advantage for this toy.

Someone counted the laps: http://www.eevblog.com/forum/projects/batteroo-testing/msg1096834/#msg1096834
I wrote a Python script, using OpenCV to verify it and to measure the individual lap times, and the counts are right:

EEVblog has verified the test with a different train model, but the same bad results for Batteroo / Batteriser, see here: https://www.youtube.com/watch?v=Tl90m2KHbNk
It is very likely that any toy with motors has the same bad performance, reduced battery life, if you use it with the Batteroo sleeve.

Flying with my Phantom 3 in Cologne, Rheinpark and Rommerskirchen. The fast low altitude flight in Rommerskirchen was in "atti" mode, without GPS. So much fun downwind at 25 km/h wind speed, I could do this all day long :-)
PS: Most of Cologne is a CTR (controlled traffic region), but the next airport is more than 1.5 km away, which means 30 m altitude is allowed without calling the airport tower. Rommerskirchen is not a CTR, so 120 m altitude is allowed.

If the sun is shining and every bench in the shadow is taken, it is good to have a mobile chair. I bought the Alite Mantis 2.0 Camping Chair. It is light and small, can be mounted in seconds, and it is very comfy, perfect for FPV flights.
And I bought another copter, a Unicorn 220 FPV, because it looks cool, very compact and stable. It flies fast and powerful as well, didn't expect it when I started it first :-) The built-in camera is not as good as the RunCam Swift which I recently mounted in my ZMR250 copter, but still good quality. There is a switch to choose stable, horizon or acro mode. Acro mode is disabled when delivered, but can be enabled when connecting the copter via USB to a PC and change it in CleanFlight, which is installed on the flight controller.
There were transmit problems because I was recording with an extra VCR, and its antenna was near the ground. Need some more cables to connect my FatShark to the VCR.
