Default When is it time to buy new batteries?

Hey guys,

I started flying my electric foamy about four years ago and then got sidetracked and probably have not flown it in at least two years. I was just wondering if it's time to buy some new batteries or if the one's I have will still be okay.

If the batteries take a full charge and if they remain balanced, go ahead and fly them.

What is the voltage of the pack, at rest.  If it is less than 7.5V, you could have a problem.  Be careful and charge it slowly.

If it is higher than 7.5V, you should be fine, but watch it closely.  I would still consider doing the first charge at a lower than usual rate, say 1/2C or  750 mah rate and again, just keep a close eye on it.   Be sure you charge in a fire proof container away from anything flamable.

Am I expecting you will have a problem?   No!   

Hope for the best and plan for hte worst.

If the pack takes the charge and the plane seems to fly fine, you should be fine.  Again, you might want to take it a little easy on the first flight for the battery and the plane.    Servos can get sticky, glue can let go, check everything over very carefully before you try to fly the plane.

Stuff happens.
