Have you ever wondered how high your Radio Controlled model could go?  Now you can find out.  Just install ZLog on your plane - be it a parkflyer, sailplane, hotliner, or 3D aerobatic.  At only 8 grams, your plane won't know it's there.  Instantly know how high your flight went with the onboard display.  You can also record the complete flight for analysis on your PC with the serial or USB interface.
