Hi all,

I was wondering, how do lipoly flying pilots know when to stop before theire bird drops down with a flat battery?

With my NiHm powered dragonfly I can notice when the output gets sluggish and when I need to push the throttle up more.

But how do you know with a lipoly power Zoom 400?

Ive heard lipoly has the tendancy to go from powerfull to dead as a doornob in just seconds.
Should I learn how to preform autolandings then? Or is there some kind of hardware that starts beeping or something?

Believe me that you will know when you lose power (especially with a heli). The moment you lose power you should land and switch off since the cells can die if the voltage gets too low.

Ah, so the battery wont die like a brick on water? It ll gradually get flat, with atleast enough time to set er down?

My friend has found something that might provide with a little more security.


This thing starts beeping at a certain voltage, so I know when to stop, and save the pack from exausting itself. Is this a method commonly used, or doesnt it work that well?
