If that's the google translator at work it didn't quite get the job done.

However, in general it is amazing what the guys from the Czech Republic are doing with props. I finally found my favorite prop for my Pletty Advance-powered Caelestia, which is the Mejzlik 20.5x12WEL. It weighs in at 43g, which may sound a bit "hefty" (LOL) by current cutting edge standards, but the blades are very wide and the downline braking is perfect for a slippery airframe. I have a similar APC prop that weighs 146g.

I don't have a figure for the Amp draw. However, I have confirmed several times consumption of ~2300 mAh for AMA Advanced sequence in fairly windy conditions.
