As the title says , how long do you get out of your standard 8FG battery pack before you have to charge ?

It lasts 1.7Ah.

The 8FG draws 195mA with the backlight off and 224mA with the backlight on. Individual mileage may vary.

About 4.5 hours on my standard battery in my 8fg then recharge. At this point my battery voltage is 7.1 volts and my low battery warning is set to 6.8v
On one occasion, I went to 5 hours and the warning buzzer came on. I was flying at the time so landed within a minute, in full control of the model. My safe flying time 4.5 hours but I keep an eye on the voltage.
I carry a spare tx battery just in case. A lipo in the tx will give you more flying time per charge but I personally don't want a lipo in my tx. So I'm a dinosaur! ;-)

Thanks for that info , very helpful.

I also am still a bit iffy on putting a lipo in my TX , no real reason but it sort of seems over kill .

I was just asking to get a bit of an idea becasue the smaller pack is alien to me in air radio's and was a little concerning to me .

Thanks again , I feel better now having a guide time to work off .

I had the chance to fly Futaba's new radio, the 8J over the weekend at E-Fest.
Without getting into details, the battery power is 4 AA cells. You can put a nicad/nimh in it and the radio has a function setting for that, but the point is that I had over 4 hrs on the TX over the weekend and the battery level was still over 4.6v.

The manual recommends to cycle the stock pack for optimal performance. After cycling the pack down to LVC a couple of times i got +7h of continious transmitting operation. I belive that many skip this critical instruction and is left with a non optimal pack. Before i cycled mine i had an operating time of around 3 to 4 hours.
Due to the convenience of the faster charge rates of a lipo, i am now running a 2500mah 2s lipo.

Why don't you just get the Robbe/Futaba LiIon battery? You can charge it in the model, but need the Robbe li charger. I'm not sure how long I get on a charge but I have about 60 flights on my ENV at around 10min a flight, plus some setup, and I only remember charging twice and that is when I get to 7.4V.

I haven't seen that battery and charger available in the US yet.

But cycling the stock pack definitely helps improve the operating time.

I was down to only getting 3hrs, I let it cycle on my charger twice, and now I'm back up to about 7hrs.

And the very first charge before you use the TX should be slow over 15 or 16 hours at about 110mAh charge rate.

dchekas,

If you do not mind me asking? What settings are you using on your charger/cycler for the stock Futaba TX battery for the 8FG Super? I would like to set my charger up for cycling & charging my TX battery but just have not taken the time to figure out what to set my charger at to do it. I have been using the factory Futaba charger. The radio is fairly new that is why I have not got in a hurry to get it cycled.

The stock battery take like 17 hours to charge.

I can't wait that long. I mean you get up at 8, and by the time you fix a cup of coffee and read the local rag, You have an hour two tops before heading out, just to realize that you need to charge you battery.

And you can not fast charge the stock battery.

Just out of curiosity, who goes off of the timer to determine when the battery needs to be recharged?

If you plug in the radio the night before you are going to fly, you are all set to go when you get up the next morning.Team Synergy/Rail, Team Scorpion, YS Engines, VelTye

John Davis,

Sorry for the delay in response!

I charge mine at 0.2 Amps.

When Cycling, I discharge to 1.1V/Cell, and charge at 0.2 amps.
I've only had to do it once in the year or so I've had my 8FG.

About the stock pack, can you still cycle the stock pack to improve the operating time latter or is it too late if you don't when it's new ?    ▲

I did not cycle mine when new.

I cycled it after I noticed a severe loss in battery capacity.

I think I programmed my charger for 3 discharges/3 charges. It was like new on the next charge.
