Run time

[d.a.v.e]

Out of the box stock what kind of run time can one expect to get with 2 2c 5000 lipos?

Trying to figure out how many packs I should expect to have as I don't really live close to a pond and the one closest to me does not have power to do any charging at.

I run the 40c Turnigy 5000 packs and Im getting about 4 min runs..I charge my packs off of a Automobile battery..Also,I have bec disabled and are running a rx pack..
