Just getting the hang of this and want to get some LiPo's for longer flight times with my Axe CP without going brok. Saw the Esky 10C 11.1 1000ma batts for around 14.95 + shipping. Any one using these? Would 10C last without burning out or over heating? I know 15C would be better.

Thanks.

I'm useing 10c 1200mah lipos with no problems.Been useing them everyday for 2 months.

I'm using those batteries right now with no problems.

Hmm... I'm using the ESky 11.1v 1000mAh packs too, but mine seem to get hot. Not hot enough that I can't hold it after a flying session, but hotter than I'd like.
I use 7.4v 800mAh packs on my CX2 and Honey Bee FP. After flying those helis, their respective batteries are warm, not hot.

I'm thinking that the ESky packs might not be the best choice for the Axe CP.

Thanks Everyone for your input. DriveWRX, that was what I was thinking would happen. I'll wait to hear from some others before I go that route.

Thanks

For those who have the E-Sky battery (EK1-0180), is this the adapter that you are using: [link=http://www2.towerhobbies.com/cgi-bin/WTI0095P?FVSEARCH=GPMM3135+&FVPROFIL=++&search3=Go]Great Planes Deans Micro/JST Male Adapter[/link]

Id go with a higher C-rated battery, somewhere around 15C plus. 1200-1300 MAh pack should be fine. with a 10c pack you could probably be dumping them to fast. Just my opinion, you should be getting around 12 min flights +- a min or two depending on your flying. Batteries should be warm but not hot. Let batteries cool before recharging.

That adapter will work.
Or you could do what I did: I took the JST off the ESky battery pack and put on a Micro Deans.

But, this battery pack is not the best for the Axe. I use it because I already had it.
If you do decide to use the ESky pack, land often and check temperatures. I also try to keep my flights at 8 min. or less.

Good luck!

Thanks for your input guys. I've been reading about these batteries and there seem to be variable results - some say they work great, others like yourself are saying they have heat issues. I'll try them out and see how they behave for me.

Just a quick review for using the E-Sky LiPos (EK1-0180) on the Axe CP.

So far it's running really well. Since it's thinner than the stock battery, 1/16th inch of foam padding on either side of the LiPo will stabilize it; it also extends a little under an inch more than the stock battery. The LiPo is running longer than the stock NiMH batteries but I can't tell if I'm getting more power from the LiPos or not (I don't know how to measure that). At the end of a session, the battery is warm to the touch but the motor is pretty hot. Charging usually takes about 1.5 to 2 hours. Also, a Deans Micro to JST Male Adapter is required for this. You can get one from the link I posted above or you can get a [link=http://www.hobbypeople.net/gallery/625072.asp]Deans Battery to Speed Control Connection[/link], which I'm using.

McFlurry, DarthDrk has a point in what he said and I agree with him, but it sounds like your a new pilot like me and don't seem to be doing too much aggressive flying or 3D. If that's the case the pack you have will work for a while.

Your pack has a 10 amp continuous rating. The Axe pulls around 5.5 amps from the main motor in a steady hover. The tail maxes out at 2.4 amps and usually pulls half that in a hover. So you'll be at 7 or 8 amps at most while hovering around getting the hang of things, however resist the urge to go full throttle for any extended period of time. At full throttle the main motor pulls 11 amps which could overheat and ruin your pack.

That's why I say this pack will work for a while. You'll get to a point where your flying will pass the packs continuous amps as you progress and demand more from the heli. Another thing to consider is the hotter a pack gets during use the shorter it's life expectancy will be.

I also have some other suggestions that you may help. If you haven't already cut the main motor heatsink so the the side vents on the motor are exposed. It will run much cooler.

I too used foam padding at first, but found it held in heat as well as the battery so an alternate method might be a good idea. I ended up making a tray out of lexan and taped a bit of cardboard onto the pack to take up the movement.

Good luck!

Heliko-- also remember that the C rating on LiPos is often, well, optimistic. I haven't measured it, but I'd be surprised to get more than 8 amps out of this battery without over stressing it.

Your right Oster they can often be optimistic, but it also depends on the brand to an extent. I know an E-sky pack is no TP pack, but he's already got it and if he's gonna use it that's the best advice I can give him. He's just gonna have to watch it closely and not push it. I've already read a bunch of other posts of guys using similar packs and they worked OK. I wouldn't do it, but to each his own.



BTW McFlurry how warm are your packs getting?

Your advice was spot-on, man. I'd just be careful about getting over 8A or so.

Cheers.

Heliko, osterizer, I'm a very new pilot so this LiPo works great for me and those in a similar situation. I'm far from pushing the Axe in any respect. I'm just at the point where I'm getting comfortable with the tail-in hover, so I'm not pitching, rolling, or yawing very much at all. I'm also not throttling up more than 60 or 70% so I'll be working well within what this LiPo pack has to offer. I'm not hovering continuously for more than 5 or 6 minutes at a time so the pack is in the upper ranges of warm. For the moment I have the foam padding but am considering using a material that will disperse the heat better. As for the the motor, it is warmer still - slightly hot - despite having cut the slits in the main motor heat sink last week, following a tip from PilotLight.

So, until my next plateau, I think this E-Sky LiPo set is gonna be just fine. The performance is just right for my skill level and, at about $42, the price was right. Thanks Heliko and osterizer for your tips - I'll know who to come to when I'm shopping for my 15C LiPos.

Enjoy, s_mcflurry. All the details aside, these things are just way too much fun .

Osterizer, fortunately, most of the fun is in the details - a good hover is a direct result of pouring over them. It's pretty much a win-win situation for me. haha...

Ha, yes, this is a poor hobby for those who don't like detail work, isn't it? But I like the flying part, too.

Yeah, I like the whole flying bit too - but it has its ups and downs...

*taps mic* ...is this thing on? Tough crowd...

Boooooo.... hissssss..... boooooo......

LIPO

I have a DN 1350mah 20C for my Axe CP , I am unable to charge it. does anyone know what jack is on the end of this battery?
I alos have a MRC super brian 989

I am having no luck in buying a lipo balancer, they electric fly and the blinky are sold out.

Is their a balancer out on the market that will show the voltage of each cell? Is this over kill?

Oh yea, the local hobby town has the axe cp 147.99

there is also the hyperion and the one from www.commonsenserc.com that is the same as the blinky

dunno about the dn connector. Are you talking about the balance end, or the discharge end? A pic would be very handy =)

oh yeah, and the charger at csrc about $100 bucks shows the voltage of each cell.

Hi everyone
I'm using the common sense 10c 1250mah
motor gets hot but batery seems fine
Motor got hot with stock batery
