Ask that question again Fletch124. I don't think your question is complete.

Hey Chevy.. I mean Fletch... I'd say that cycling any battery pack is not really needed except maybe to test a new pack or one thats been sitting a LONG time, maybe once a season otherwise just to verify it'll hold a charge for say a transmitter on for about 2.5-3 hours...

I wouldn't just leave anything on overnight to completely discharge it. Doing that can bring the weakest cell in a pack extremely low and maybe into some kinda reverse polarity thing (which I've never seen but trust some of the battery gurus enough not to do it!

You can just leave the transmitter on for a few hours and check it every 15-30 minutes, just stop when it goes red or beeps. receiver might be a little harder in that unloaded a receiver only draws like 20ma so you'll have to play with the sticks a bit to really pull juice... If you have any park flyers maybe hook up the receiver pack to a propless motor and let it run until ut slows down, then recharge as normal overnight...

hope that helps some.

thanks so much Trogdor the Burninator i didn't actually leave it over night i started it at like 4-5pm and when i went to bed at like 9-10pm it was blinking red i think. I actually rubber banded the sticks into positions were as many of the servos would be were they are holding the control surfaces in like up elevator you know.

yeah i thought about that but i don't want to not fully charge the battery. i can't tell if i did fully charge or not because i don't have a tester. i could make a tester out of the ones that electricians use but i'd need to figure out how to do it. and i don't want to pay $50 more a one met for RC. so i'm kinda in a hole as far as voltage testers go.

You need a "Pulse" Charger.
Something like the Electrifly Triton DC Computerized, Charger, Discharger, and Cycler from Great Planes.
Tower have them for just over $100.
Great Insurance, and "set and forget." (to a point anyway)
The Rx battery is the weakest (and usually the most neglected) part of a model.
I've seen people happy to spend $100 or so on a new plane (after theirs went down terminally due to a bad battery) but won't spend the same amount of a decent charger/cycler which would have prevented the crash in the 1st place.
Use of one of these will also prolong the battery pack life.
