newflyermx -> What airframe are you using with your A123 3S packs? (6/12/2007 7:27:40 PM)

Hi all,
I got 3 packs of the A123 Hypersonic 3S1P and a charger.
I got a big surprise when I realze that the packs won't fit on my current planes.
Since I was already planning to get a bigger plane, I would like to know what Airframe, Motor and ESC are you using.

I have very few experience on RC flying so any help on deciding what plane would be a right one for a newbie will be very appreciated.
Thanks
AA

I am using them in a Telemaster Electro (Hobby Lobby). You have room enough to put in just about any combination of batteries you can think of. AXI 2826-12 swings 13 X 6.5 APC E prop. Have had to open the bulkheads on 4 models that were previously glo (.40-.46) powered, aslo with same motor and prop as Telemaster.

Hi red, thanks for the response,
Are you using the Jeti 40 ESC?
3 cell packs?

How much time are you getting on this plane with the A123, 3S1P ?
Thanks
AA

I also am flying a E-Tele with the A123. We are flying 4 cell packs to take the place of the 3 cell lipo. I have an LT 25 with the same setup.
My Fledgling calls for a 2 cell lipo, I use a 3 cell A123.[:)]



newflyermx -> RE: What airframe are you using with your A123 3S packs? (6/27/2007 5:46:29 AM)

What do you think about the Hangar 9 J-3 Cub with a 6S1P pack?

Was Thinking on the next setup.
Motor: E-Flite 46BL 670kv
ESC: CC PHX 60
Prop: APC 13X6.5E
UBEC

http://www.horizonhobby.com/Products/Default.aspx?ProdID=HAN4350
Wing Span: 80 in (2032mm)
Overall Length: 51 in (1295mm)
Wing Area: 932 sq in (60.1 sq dm)
Flying Weight: 7-7.5 lb (3.2-3.4 kg)


I'm waiting to the Scorpion 40mm Series Brushless motors to come out, they are suposed to be in the final stages of develpoment

Hi red, thanks for the response,
Are you using the Jeti 40 ESC? Yes, I'm drawing 32 amps max with 4SA123 and about 30A with 3SLipo and ju
3 cell packs?

How much time are you getting on this plane with the A123, 3S1P ? 4S2P A123 - about 20 minutes or more with throttle management. Same for 3SLipo packs

Thanks

dick Hanson -> RE: What airframe are you using with your A123 3S packs? (6/27/2007 5:54:55 PM)

I have a AJ300 and a Diamante -both fully aeobatic -both weigh ready to fly 3.4 lbs . both 500sq inch models
on 13x8-14.7 APC props on 32 EFite motors and Align 75 amp esc and ParkBec BEC
Contrary to the BS I got from the hard core lipo fans --these models will do all the stuf easily with the 4 cell 123pack
amps are 40+ as needed
flight times easily over 8 min and 10 min for no 3D flying
I use up to 2 amps on a flight no real heat in the cells just warm. I am NOT pushing them at all.
next up is larger aerobatic stuff.



klhoard -> RE: What airframe are you using with your A123 3S packs? (6/29/2007 2:11:11 PM)

I was using 3S packs in a Fliton Mini-Inspire. TONS of vertical, amps, and pulling power, but unfortunately when the plane wasn't going vertical it was a brick with wings. I broke the landing gear multiple times because of the speed I had to keep on landing. The wing loading was high and it would wing rock violently if you got too slow on landing. Went to LiPo's (reluctantly) and now the plane flies well and lands slow.
.
.
My 2S packs work wonderfully for chasing geese in my Duratrax buggy, and the two 3S packs are going to be re-purposed as dual receiver and ignition packs when I get my 50cc gasser. . .
.
.
Don't get me wrong, the A123's are THE future of electric flight, but right now they're too heavy for any set of wings I have in my stable. . .

Night_prowler26 -> RE: What airframe are you using with your A123 3S packs? (7/12/2007 5:38:48 PM)

This is a great thread to see what all people are flying them in, on your plane what was the wingspan and sq in and all?
i was wondering what would be a good smaller plane to use them in, I have a Mini edge but I think it needs a few more inches of wing span to work with them. me and my father figured out if you have a over 40 inch wingspan with over 400 sq in of wing area that would be plenty for a 4 cell pack

Well Now I can add to the list, I flew my E-flite mini Edge with a 4 cell A123 cell pack today, it flys great, still has a decent glide rate and the stall is not any worse then with the 1700 lipo pack.
lack of 3D with it, being the plane is at 32 ounces now, but sport fly loops,rolles,knife edge,spins,snaps.inverted(nose pitched up) it flys great. 2300MAH with that pack flew 8-10 minutes at 10 mins half-3/4 stick still have plenty pack left to run the radio and have juice to land.

landings were fine also. it glided a little faster, being weighing more but any plane would, these planes you need to fly like a real one, up elevator keep that nose up and make it slow down.


BTW half thorttle is 225watts of power. these A123 cells really juice the plane, now I need a 45 A ESC to go in her before I cook my poor 25A one.



Tex Gehman -> RE: What airframe are you using with your A123 3S packs? (7/19/2007 10:17:52 PM)

I was using 16xGP3300 packs in my Venus 40. Now I'm using MEC SPTs with M1s in 6sx2 paralleled and I lost a bit of weight and gained power. Tex.



Red Scholefield -> RE: What airframe are you using with your A123 3S packs? (7/19/2007 10:38:21 PM)

Here are a three more that are happy with 4S A123 packs, all were originally .40 glo powered.



Night_prowler26 -> RE: What airframe are you using with your A123 3S packs? (8/10/2007 9:55:43 PM)

here is the latest, My dad just got a Extreme flightrc Yak 54E and he flying it with a 4cell A123 pack also. seemed to be doing good in it only have one flight so far on it.

He is also getting ready to use them on a old Sig Fazer glow plane that the engine just craped out on so got a Axi ( not sure the Number) and going to be using a 60A CC esc on it.. It should fly nice.



bobferguson -> RE: What airframe are you using with your A123 3S packs? (8/11/2007 9:27:55 AM)

Does the Rascal have a hatch for the battery or do you have to remove the wing? A picture would sure be nice.

dcnpaulk -> RE: What airframe are you using with your A123 3S packs? (8/11/2007 4:24:26 PM)

Red,

I note that you have used 4SA123 packs in your Telemaster Elektro and several other 0.40 size conversiona. I assume these are all 2P configurations? I just bought a Telemaster Elektro and am building my own packs from DeWalt M1's. My question: Is it better to hard wire the parallel packs together and make one integral pack or two 4S1P packs and join them with a parallel adapter in the plane? Is there any difference in efficiiency charging, or in balancing the individual cells if I charge/balance the packs separately or as a unit?

Sorry about the mis-post. Not used to this forum yet. I replied to the wrong person. So here goes....correct this time I hope!

Paul,

I am not Red, or my father, but I know my father just makes up the packs as one. each cell conected together just like any other pack would be, I don't think there is any advantage of having them seprate you can put balacing leads so you can balance each cell together or seprate, if you know what your doing.

I use them as individual 4S packs, then paralleled in the plane using the Deans parallel adapter plug shown in the July issue of Model Aviation Battery Clinic column. I use them as single units in a couple of my powered gliders. There is no difference in efficiency in flight, but I do like to have the ability to charge and balance separately.

Yes, I put a hatch just in front of the landing gear. I was not sure exactly where the battery would be best so I allowed quite a bit of room to move it back and forth to get the proper CG. As you can see it ended up as far forward as I could get it. In this case I use 1 4S A123 pack rather than paralleling two of them. Flight time is adequate with throttle management. I also use a 3S 4800 CellPro Revolution pack for longer flights.



dcnpaulk -> RE: What airframe are you using with your A123 3S packs? (8/12/2007 8:43:44 PM)

Thanks to both Night Prowler and Red for your replies. Two different answers! That's good, because that means neither one can be wrong! Seriously, I think it means it's just a matter of choice and convenience, both will work o.k. I think I will choose Red's system of two separate packs physically, because in case of a cell failure or damage from a crash (we don't do that though, do we?) it is easier to replace one pack. Also, since I will be using a balancing charger (FMA Balance Pro HD) I prefer to balance individual cells, rather than pairs, since the paired cells would have to be joined electrically for the balancer to work and charge properly. Thanks.

Night_prowler26 -> RE: What airframe are you using with your A123 3S packs? (8/20/2007 2:07:22 AM)

There is no wrong answerers here [:D] Yes its a matter of how you would like to do it. I would want 2 separate packs if i were in need of 8 cells I could have 2 4 cells, then if I have a plane for only 4 I could use one pack in it alone but when I go to fly the bigger plane i could put two together, so that kind of situation makes sense that way.

In a crash, well I have seen one plane go in with a 4 cell pack and it didn't do anything to the battery's, remember there in a hard case, Unlike a lipo that would have got chewed up by the motor and caught fire, I just love A123's..



vollrathd -> RE: What airframe are you using with your A123 3S packs? (8/24/2007 6:25:50 PM)

I've got a Hacker A30-12XL in the Extreme Flight Yak with four A123 cells. Motor spins a 12/8 at 7700 RPM. No, the model will not hover, but if I wanted a model to hover, I'd buy a helicopter. With a 3 pound airplane, this model will do most any acrobatic stunt, it gets 6 1/2 minute flights, with about 60% of the battery capacity used up. Take off is about 15 feet from short grass field.

The Yak has some 40 flights on it now, several other members of my RC club have purchased the same set up, one is getting ready to sell all his glow engine stuff, and go electric 100%.



Night_prowler26 -> RE: What airframe are you using with your A123 3S packs? (8/24/2007 10:15:13 PM)

I don't know much about the hacker motorsd other then there great, my fathers yak will hover , about half stick, it flys around great on the 4 cells. what size prop you running?

I use 7S1P A123, AXI 4120/14, APC 11x8.5E, UBEC, CC 60A controller in a converted World Models Sky Raider Mach 2.
Power level of 970W (measured) is pusing the motor a bit. It flies too fast for me! Proping down to APC 11x7E.

Practicing to get comfortable with it so I can join in the Club 40 pylon racers - they use the same airframe with .40 glow engines for fun pylon racing here in texas and elsewhere. It's fun!
