About the Picolario: http://www.picolario.de/picolario_ta...lario_talk.htm

You have to deceide if you want to read out graphs after flight or want to use the datas during flight. During flight you can`t watch a screen...

Then the picolario is unique because you get all the info you ask for to your ear. But the info is made for sailplanes especially.

Small altimeter-loggers like RAM" and ZLOG is meant for DLG and winch-launching to read out which zooming and throws that works best (best height). But I have used this to check out climb-performance on motor-gliders too; log the time it takes to climb to 200 meters on different setups.

All the logging-devices are (in my opinion) good if you want to explore how motors load/unload during flight etc, nice for the first flight on a setup, but after that useless. Or: a gadget, nice to have and play with...
But who can resist having a lot of gadgets???
