e-Align T-REX 250-450-500-600 > T-REX 450 Air Thunder hammering on a 450F motor

i use and recommend FlightPower EVO 25's 2170, but today i had a flight with Corona44 and he asked me to have a go of his AirThunder lipo 25/30C 2200 lipo, and he said to fly it until it cant fly no more...so i had to ask him about 3 times if he is sure about it as my 450F motor can kill lipos

i ONLY fly for 4mins religiously on my FP EVO's putting back no more than 1500mah (too expensive to hurt)

so i spooled up and gave it NO mercy and hardly gave the lipo time to breathe or the motor for that fact

and past the 4min alarm on Tx and after the tail was twitching, i thought i'd better land as HS was dropping and looked at the timer saying 5min50sec and it was warm to the touch , motor and ESC was pretty luke-warm too

and i just recieved a PM from Corona44 saying he just finished charging it and putting back 2193 mah

power was consistant throughout and impressive against the FP EVO25's

UNBELIEVABLE!

!boo!

Sorry but one complaint on one battery doesn't make a trend. As with anything man made there is a failure rate that is not zero. I would go by the majority of the users when it comes to the capability of the batteries specially when they are abusing them to try to make them fail and they still hold up.

I'm just trying to help like all of us do here,but I do think it was more then one battery. I think it was two or more? So time will tell all things.I read,, the AT are also very heavy?
AT 2200 190g.
TP 2200 extreme 170g ! That is about 4 quarters more in change on the nose of your helicopter!Over the same size of TP 2200 extreme battery.

I'm flying the Trex450 with about 15 quarters more with no performance problems
---------------------------
FYI when it comes to weight. Here is the trend of the other popular brands out there including the TPX 2200. And I started with TP 2100 prolites.

Thunder Power 3S
TPPL 2100 / 15C / 4.7 oz
TPx 2070 / 25C / 5.78 oz
TPx 2200 / 25C / 6.0 oz
TPx 2500 / 25C / You fill in the blank...

Flight Power 3S
FP 2170 / 25C / 6.2 oz
FP 2500 / 25C / 7.37 oz
-----------------------------

Yes, ALL battery brands will have defective batteries from their manufacturers. What will suck is if the dealers do not warranty or have a replacement program established.

hey
dct i don't know what your problem is but i would recommend doing more reading than just one post you found on another forum.

Airthunder not only has great batteries but great customer service; proving it time and time again with replacing batteries that were defective (very few) and refunding for batteries that peoeple just didn't want...

do a search on RunRyder and then tell me what you think


sounds like you are either:
A) getting paid by the competition to trash AirThunder
B) ill informed and made an honest mistake
C) just like to find all negatives in a product and try to feel like you made a difference

i guarentee you an intelligent person on this forum(or any where else) would read up on material regarding the battereies before they buy (or i would at least hope so). They should too no doubtly because AirThunder is a fairly new company.

However, until you have personal experience...come on buddy, spare us the blind ignorant product thrashing and get some real facts


Thanks

I have a buddy of mine that is an Air Thunder rep, and he too says they are pretty good. I think we should give them a chance, just because they are new, and not proven, doesn't mean they are going to suck. I too think that if you drain the battery all the time, it can't last too long, but I know if I over discharge a TP/FP battery, that dude will puff up like crazy, and I have seen mulitple vids proving this battery does not. I am going to be ordering a few of these for my trex 450/600 to see how good they work.
I still think TP/FP are great, but if you can get something just as good for the same or lesser money, give it a try..

break it now and get it over with!

First, I don't know what YOUR problem IS?
A)answer,NO
B)answer ,I'm not ill informed ! I just pointed out the post what others are saying about AT.
C)answer, I do like to make a difference in people lives ,and if there is a negative it's in the other post made by other people using this battery not by me,I don't own one!
Next, thanks for your understanding .(intelligent person want to know!)

first battery test results
11.1 Pack #1 7:30 mins put back 1257mah back in pack
Pack #2 8:25 mins put back in 1408mah back in pack
Battery temp on #1 pack was 108 with air temp at 95
#2 pack was 112 with air temp at 96
these are 2200mah packs and definatly have a lot of punch
On the 2nd flight I broke the Jesus bolt that holds the head to the main shaft.
22.2 7mins put back 2905mah pack temp was 110 with air temp at 96 running 1980 head speed on trex 600.
These were Kong Power batteries which are the same formula

I tested the Kong Power 2200. Worked great for 40-50 cycles and then it lost major ass. But so did my TP2200 which TP promptly replaced. I would say these new packs are good sport packs for the newbie or the guy sport flying a 600. I did notice the extra oz on the KP2200 but at first the Eagle Tree spit out equal numbers to my new TP2200's so I did not mind. I doubt I got a lame pack. Its just most of us are pushing these packs to the ragged edge. But a 25/50C rating is a little optimistic on the TP and KP packs. See have many cycles you get a 50amps let alone the 100amp burst.

I haven't had computer access since Sunday so I was pleased to see Menace's post about flying one of my Air Thunder batteries in his Trex 450SE here in Sydney. While Menace did state it in his post above, he is running a flat line 100,100,100,100,100 throttle curve and a 11 tooth pinion, using a SkyTach optical tacho I checked his HS at between 3050 & 3100 rpm with no sign of bogging while he thrashed that heli around the sky doing things I only dream of doing in a sim.

I currently have 5 of these batteries that I being using in both my Trex 450SE and my new bigger Hurricane 550 which uses 2 of these batteries in series for 22V operation. I was also using them in Multiplex Funjet fitted with a 450TH that was pulling 40+ amps and killed two align 2100 packs (puffed up badly) but the Air Thunder take it all and come back for more.

These batteries are now about 2 months old and have been punished where I keep flying until I have to land and they are still going strong.

I'm still new to the whole heli thing so you could best describe my flying as "sport", rolls loops etc. and with 430L and 13 tooth pinion I get around 13 minutes to each flight.

In the big Hurricane I'm getting 8.5 minutes and that thing weights 2Kg and typically putting back about 2100 -2300 mAH.

Here on Run Ryder Air Alpheus has been really punishing these cells and has over 100 cycles on one of his batteries that he has distruction testing down to almost O volts and its still going, try that with an ordinary Lipo, see this thread in the battery forum

http://runryder.com/helicopter/t339993p1/

There is now 15 pages of posts, thats how much interest they are generating.

One final thing, for packs that have been as discharged as these have been, these pack are still perfectly "square" as the day they were brand new, zero signs of any puffing up at all!

Well Im at 110 cycles on the test cell that AirThunder sent me and I beat that battery worse than anyone at this time can claim and it is still going strong. Ya it has lost some capacity but its getting old and has been over discharged on every single cycle and drained to 0 volts more than 10 times. You are always going to have nay sayers in this hobby. Some people are dead set against change and some people take what Finless says as LAW. Theres nothing wrong with that He is an intelligent person who helps alot of people out in this hobby and I respect him for that and He is entitled to his opinion. but That will never change. The testing and hundreds of posative testimonials speak for themselves. Plus AirThunders customer service stands out as one of the best in the biz. They listen to their customers input and make changes the next day if it warrants. I am very pleased with the results from my personal tests on this battery and will be using AirThunder from here on out. But one of the main reasons Im sticking with them is not only do they make a excellent product, but its that if I ever have a question or a problem of any kind I know I can pick up the phone and call and someone will always answer the phone and solve the problem...

Did you really mean 13 minutes? I could believe that maybe if you were using a 10T pinion, but with a 13T pinion and that motor I'd expect more like a 7 minute flight time.
