Do you guys check your voltage on the field? how do you determine when the current pack is done for the day.

I found a post over at rcgroups that list the capacity vs. Resting voltage.

4.20v = 100%
4.03v = 76%
3.86v = 52%
3.83v = 42%
3.79v = 30%
3.70v = 11%
3.6?v = 0%

These are resting voltages - not under load voltages.

I have a cell checker and supposedly it goes off when a cell goes below 3.2v. It may be going off at 3.6v though. I better check that

Is that the little hobbyking buzzers? How does it work? well, I was thinking of getting something like that, anyone have suggestions? The local hobby shop showed me a meter that you can supposedly see from the ground, yeah right...

It is the little 3s voltage warning thing sold at hobbyking. The light goes from green to red when the voltage goes below "3.2v". If you fly during or past sunset, you can see the light, even from very far away. It turns red before the battery dies so it should make your lipos last longer. I highly recommend it.

you are confusing voltage under load with idle voltage.
If it can not fly with NiMH it is not a plane.

Actually there IS one you can get where it plugs into the plane and sends battery voltage readings back to a piece you clip on to your TX.

The new Spektrum DX8 they made so much fuzz about among other things utilizes built-in telemetry. This includes a voltage display on your remote. If you got the bucks, that is of course
