I was talking about my ALIGNS. I also have TP's.

I was looking for replacments for the ALIGNS. I have a 11tooth pinion to upgrade the head speed. I fear it at the mounment because the ALIGNS get swollen and hot on a 10 tooth. I know the 11 tooth would ensure a quicker death. Im pretty positive the TP 5000's can handle it, just at a lower flight time. Im guessing around 5 mins. I can almost pull 6 mins on the 10tooth.

I paid around 225.00 each for my align 4600's and I hate to kill them on a bigger pinion.

Im having to run high throttle curves for a -9,0,+9 pitch. My throttle curves are 100,97,85,97,100. Anything less than that I bog.

I was wondering if the AT's could handle a normal curve of about 100,85,100 without bogging. I can only seem to manage about a 1850 HS for about +-6 degrees of pitch, above that and below that massive bogging.

Do you all think they will hit 300 cycles with good punch and life?
If they last 100+ cycles when totally abused, imagine how long they would last when ran to...say...85-90% compared to 80% for TP's and FP's.

My purpose would be to eliminate the timer and/or low voltage alarm. Just land when you notice a significant power loss and have confort in knowing that you didn't just fry your $260 lipo. Imagine doing that with a $300 TP or FP pack. I bet you add almost 1 minute of flight time with that extra 5% - 10%.(ie. running to 85%-90% of lipo capacity).

Hold your horses a bit.

Im not done with my testing yet, but where is what I got so far,

Its true that you get longer flight-times with the Airthunder, however there is a few considerations.

An AT 6s1p 5000 pack gives you around 20% more flight-time since you can run it to the bottom
However, its also 17% heavier then TP Extreme, and 13% heavier then FP 25C.
Meaning your "net" gain isnt that much, if for sample TP did a 6000 mah pack, it would probably weigh equal to the AT and give you about same flight-time.

Your PRIMARY gain from airthunder is that you dont need the timer, so you will get MAX flight-time, every time, regardless of your flying style on THAT flight.

Regards to voltage under load,

They are good, in the beginning about equally good as FP/TP, however, when you hit around 60% usage, voltage under load will drop and it will be from that point less voltage under load then FP/TP packs.

Now, depending on your gearing you will feel this just a little, or ALOT, if you dont have headroom it will feel like they are dying, if you run a governor with alot of headroom it will feel less.

First two flights are AT, second two is FP

Edit:
Just to point out what my conclusions of the AT packs are so far.
Its THE optimal packs for any sport flyer since you dont have to worry about ruin the packs.
For the 3D flyer like me, I suggest you have both, When I fly my 3D rutine where I need equal avg power all flight I fly FP/TP, but when Im training new routines, I put in the AT pack and skip starting the timer.
Cycle life is a factor which we havent any tests on yet.

however in any case, Air Thunder packs are much less fragile than TP and FP packs... If you breath on a ThunderPower or FlightPower pack the wrong way, they'll fry.

From MrMel's eagle tree data, it seems his ION-X2 didn't need lots current draw. If you can play AT's battery for more than 6 min (Actually 7.5 min), you use only less than 10C current draw.
As I know, AT's battery could be and best suit to haevy current draw. For more than 15C and 20C even 25C.
Those batteries you had tested only in low current comparison. This is not fare to AT. This is why AT and FP's batteries both look so similar.

?? So you promoting 2 minute flight?

Yes, Its 10C avg, its a helicopter, im pushing 20/25C in peaks with it though, see earlier graphs in this thread.

I just overlap picture 1 (AT) and picture 3 (FP), I don't observe any different between AT and FP in the FP's play time. It seems AT can play the same voltage as FP can do all the time and AT really can play more than 30-40% longer than FP does. From MrMel's eagle tree. I had painted figure 3 to violet color which will be more easy to read.

You need to put the MAH lines overlayed as well,thats why I show them, thats your point to see which flight is harder then the other.
As you will see the mah line of the flight 3 is steeper then flight 1 meaning flight 3 is pushed harder.

Doing that will show you though that flight 2 and 4 is equal in rate of current draw, so if you gonna overlay voltage to compare you need to take those two flights.

This is the problem with heli's, hard to do exactly two equal flights

Should add that even though if I could do two perfectly equal flights, the AT tests would still be "unequal" since AT is heavier, on my Ion we are talking about 6% difference in total weight.

Thats why we have CBA's for pure voltage tests.
I will receive some cells that I will test using my CBA+10X amplifier later.

the biggest selling point with AT batteries is that you don't have to worry about puffing the packs nearly as much as an FP or TP pack... When I fly my TP batteries, I am always worried that I might accidentally over discharge them or push them a little too hard.... AT packs don't really have that issue for the most part.

Which is almost worth its weight in gold, or at least 266.00 worth of gold.

Sometime I find TP5000's on sale for 269.00. I was about to jump on that and buy 2-3 more packs but AT's for 266.00 has made me wait for the complete testing from MrMel. If you dont have to worry about puffing and the AT's last 300-350 cycles at 80% Im sold. I have never done a 300 cycle 6s lipo. Most of my lipos have died early with non-abuse.

I actually have to send one of my 6S packs back to TP.... in the case of this particular pack, it was properly broken in, ALWAYS balance charged on my 1010C/210 charger/balancer, and never flown below 80%, and yet it seems as though one of my cells has gone bad. yippie... I don't feel like I can be confident in flying my 600 without breathing on my packs wrong... at least not with TP packs strapped in my heli..

well I got to test my AT pak today and I got 10 minutes of hover time out of it. I will post the eagle tree data later tonight or tomorrow. but I still had a little power left put back 4600 give or take. all in all I was very impressed with to preformance

here is the eagle tree data from my flight today

hover only and if you look at the 4 min mark I did a short punch just to see how much juice was left good lord I didn't think there would be 6 mins left but man it flew for what felt like forever. I can't wait to do a second test to see how long it will go in tell it just will not fly. I think I was very close to the end of the pack. 4600ma give or take and still had a little left. the cg on my heli was perfect and the added wieght was well worth the flight time I got out of it.TP and EVO had better step up there A game cuz the new kid on the block is kicking there a$$es. IMO. and not having the timer tell me to come down was mind blowing.

be careful not to even fart next to your TP/FP packs... those things just try to find excuses to go bad on you... I mean, seriously, both my packs have been treated with the utmost care and respect, and one has already been sent back to TP for repair, and the other one has issues balancing, which leads me to believe that I have another bad cell. I cannot stress enough that I broke these packs in appropriately, I ALWAYS balance charge, and I NEVER exceed the 80% rule.

Well I got 12 cycles on my AT 5000 pack so far and then my Align ESC decided to let out the magic smoke so my heli is down until my new one arrives. But the good news is that I have recently aquired a single 5000mah AT cell for testing with my CBA so I can post temp tests and high amp draw tests very soon.
I am glad that everyone is liking these batteries as much as I do.
I know its hard to switch from the other guys batteries and fork over the cash to try out a newcomer to the lipo scene, but without us people who are into trying new things for just the sake of " Lets see whats happens" this hobby would become boring real quick. I applaud all of the PIONEERS that are trying out this new battery and lovin it.

On another note.
A buddy of mine was at IRCHA last week and was flying his TREX 600 with an AT battery. He had noticed a small crowd had gathered to watch him so He decided he would run his heli until the voltage cutoff kicked in. So towards the end of the flight He had the heli hovering in front of him just barely enough power to fly it and the guys behind him were yelling at him to land it because he was going to ruin his battery. After the voltage cutoff hit, the heli autoed down and one guy came over and said " that is one pissed off lipo, you should just throw it away, its done". Seems to me that we have a little more work to do to get the word out about these batteries...

Its What I dont Say You Should Be Worried About...

Amen and if AT would just make there stickers a little bigger I could put it on my truck maybe a sticker that says "Ask my why my lipo will out fly and out last your. AirThunder a whole new way of flying" I think that will help alot especailly at your local flying field

That was awesome flying dude! You know I love watching you fly.

What I love about those Air Thunder batteries is that you get really consistent power for a majority of the flight!

WOW I shot the video and I am still amazed on just how hard and long the heli was flying. and the pak came out very cool to the touch almost could have thrown it on the charger right away it was that cool. good job on the flying Errol and next time the video will be even better.
