ANOTHER STUPID QUESTION
Knowing the Mah battery rating and the amp draw of the motor, what is the equasion for determining the flight time?
I know Lee had it in one of his posts a looong time ago, but I can't seem to find it.
Thanks in advance.[8D]

Mah rating of battery divided by 1000 is the amp hour rating. Let's say the battery is 2000 mah. That is 2 amp hours. The battery should be able to deliver 2 amps for one hour or 4 amps for 1/2 hour or 8 amps for 1/4 hour or 16 amps for 1/8 hour. For a round of combat 1/8 hour is about what you need. That being said, If you multiply the amp hour rating by 8, that is the current draw you can take from the battery. A 1 amp hr is only good for a 8 amp draw. A 4 amp hour is good for a 32 amp draw. Would you say that is about right Lee?

I've wanted to buy some 4S 4000 packs from Hobbycity but seems like they are never in stock.
I did find these:

I've got 2 of them. Seem to work as advertised.
