Voltage
 
What is the lowest voltage you can fly on?

Thanks in advance

RE: Voltage
 
For a 4-cell reciever pack, at 4.8 volts, you're essentially "out of electrons" and you continue at your risk. For ni-cads and nimh, 1.2 volts per cell is the basement.


Edit grammar, duh.

RE: Voltage
 
I usually through my receiver packs on the charger at about 5.0 volts. 4.8 is the very least in my opinion.

Usually, no less than 4.8v on a 4 cell pack.

IF you could depend on it having power... the RX and servos will function at 3.85 V (at that point you have about 4 seconds left... and it will read ZERO.)

The minimum I consider safe to take-off is 4.9 v with a 4 cell NiCd RX pack. It will probably read 4.7 when you land from a 10 min flight of an typical .40 size trainer. (that's pushing as far as you want to push it.)
******************
Remember this bit of trivia:

You take a dead flat 4-cell pack and put it on the Wall-Wart ( C/10... or appx 12 to 14 hrs for full charge from dad flat...) for 1 hour. What will the pack read immediately on being pulled off charge?

5.5 volts.[X(] And it can read that with a loaded meter for up to 30 seconds.... with as much as 30 min wait after pulling the battery off the charger.

But that battery is still... essentially DEAD FLAT!

RE: Voltage
 
The answer 4.8 for a 4 cell pack is correct but this has to the voltage with the pack under load not unloaded.
