ISS SSTV
SSTV image sent by international space station on 145.800 FM on April 11, 2015.
Each image was sent in about 3 minutes, with 3 minute pause between images.
This pass was very low and thus short. First image had a little noise as ISS rose over the horizon. Second image started as ISS already vanished below horizon, so missing most of it.
Another pass, only about 15 degree max. elevation, resulted in this image:
Final pass on April 12, very low, only got end of what could have been an interesting image:

Graupner Amateur
Built by using parts from an original kit found on EBay.
Started building just before Christmas 2013, first flight on 1st of March 2014.
Compared to the original, built as tail-dragger and with electric motor. Hood and front window are held by magnets, removed to access battery. Completed weight matches what original estimated for the free-flight configuration, without radio!
Flying it couldn't be better in no-wind conditions. Current draw is up to 10Amp, but plane still slightly climbs at 1/3 power, so full throttle is rarely necessary.
I happened to have grey Monokote around, so I tried to cover it as shown on the kit's box art. I'm surprised how pleasant the color combination turned out. The lettering and "Graupner" logo were cut from Monokote based on copies from the plans.
