Trex 600 with A123 cells

[ozace]

:hug: I actually like the bickering if its good natured and friendly. Its great to read whats on everyones mind, as long as its civil and not nasty.

Now time to go charge some packs for helis and cameras. :smokin:

[Mercuriell]

Don't think calling Bob an Ass is civil just darn right rude and nasty

[Finless]

Now time to go charge some packs for helis and cameras.


OK Ozace! Lets see some 6S vids man!

Spruce , man , you sure make an ass out of yourself , you sound like a cocky little young-in that needs alittle attending to at the field. one word of advice , remember when you were learing all about helis , you had tons of question , forgot most , and went ahead and asked again , duh ! get a grip dude before you get ban from HF,

[Danish Heliflyer]

as soon i get the new frame from Rotorworkz, i will put a video of it´in here. Even though it´s god or bad performance. My guess is flight time will be around 4-5 min on my flight stile... :glasses2:

[robl]

Thats an titan eraptor conversion.

The title of the Video says Logo 10 3d. I didn't examine it, I just went by the title :)

[BoneDoc]

That looks too big to be a logo 10 though. More like an E Raptor.

Garry G from TPpacks.com is pretty much one of the pioneers when it comes to these alternative cells like the emolis and A123s. His works are extensively posted in RCG, and he occasionally chime in, in the Logo forum.

[WillJames]

Take it easy Spruce, if you don't like it here and you don't want to share and you give the proverbial use the search like the other sites, maybe you should check out other "baskets" and move along.

Thank you.

[catfight]

It says right in the video lead sheet:
Raptor 50 eTitan
15S 2300 A123-M1
Z Power Z50A - 600 (565 kv)
95t/10t 2700 HS

[rdespins]

OK when you said 2700 HS I doubted it and it sounded more like about 2200 (and believe it or not I usually can guess it within 50) until he switched into idle 2.... That sounded pretty close but to me only about 2400 or maybe 2500 (too fast BTW I hope those were metal grips!).

Gotta ask though... WHY does the first segment have a "edit" in it?

However, in the second segment you better have that guy check his tach... in the second segment there is NO WAY that is 2700 inj the hover.... sorry.... However later in the flight it sounds good and high but still doesnt sound like 2700....

Last segment flight time 6:22 to ruffly 9:22... Thas only 3 minutes?

BUT bottom line this looks good... MUCH more than I expected!
Thanks for sharing!

Last question... WHY does the water mark say TPPacks?
What pinion? How many cells? etc? Please share!

Finally... looks like Saint George Utah? Where is that?

Thanks,
Bob

Hi Bob,
I just cut and pasted that link for you from RCG. It is not my work, but that of Gary Goodrum from www.tppacks.com. I beleive he is located in Las Vegas? He has done alot of testing on various E helis, mostly on TT products, but most any electric system can be transfered helis by changing pinions... if the helis are similar in size. Gary was big into Lipo, thus the name of his business, but now I think he is trying to build the most powerful setups, at the lowest cost possible, with the safest cells. Unfortunately sometimes it's hard to keep up with his ideas as it seems to end up as flavour of the month, but I guess thats how you pioneer things, by testing a s#$tload of stuff.

I am also sceptic of the A123 cells, not that they work, I can see that, but that they are right for me. The flights are shorter. And the cells are heavier. However, I think one way of countering the weight is by running on bigger helis (620mm+ blades) but at much higher cell counts (12Slipo = 15s A123). This seems to be the magic number for weight, where the difference between the two types of cells starts to blur. The higher voltage allows lower amp consumption. For me I like LIGHT and powerful helis and don't own a 620mm heli, so these may not be for me.

The A123 cells react very differently than Lipos. The Voltage drops more under load, but they only seem to drop to a certain point, then keep pumping (to a reasonable amount.)

I'm rambling on,

Ron

Sounds like these batteries are promising. Thanks ozace for the thread and great information. It will be nice to see some good vids so it will be clear to everyone exactly what you are getting with these batteries. Batteries are very expensive and we don't all do hard 3D so this may well be a good option even if only for secondary packs.

Thanks also to those that provided links. Fun, Learning, Friendship and Mutual Respect is the helifreak way. Lets stay away from the bashing please!

You want to "Attend" to me boy? You have no clue what I did when I started out.
Oh NO not banned from Heli Freak, I'm terrified. :roll: :roll: :roll: Ban away Eskimo Boy.

[rdespins]

This is getting old guys, take it to PMs.

[rdlohr]

No one is wants to ban anyone. Move along Spruce unless you have some value to add to this thread. It's been derailed enough.

[robl]

apparently people are talking about two different videos or something, the one on youtube said logo10 3d. I guess this other video from tppacks is a raptor or something.

Another update on A-123s, Charlie Wang from Thunder Power is updating his 1010C charger to includer them here is his post on RCG:

Download from www.thunderpower-batteries.com
1)V2.0D=V2.0C + A123 (available for download tonight,Thunder Power web under construction now)
2)V2.0E=V2.0C plus NiMH, NiCd(Download available in Mid January).

All TP1010C Charger shipped with 2.0C software

Other News:

[spork]

Anyone have any ideas about hacking the Triton to charge A123's?

[jlewis99]

EXCELLENT! This is one of the things I was waiting for before trying A123 cells!

[rdespins]

I bet sales of the update cord and the charger go up now.

Ron

[ozace]

:oops: no chance to get any video today, my pilot didnt make it to the field before i had to leave.

With most of the high end chargers now having A123 support someone must believe there is a future in these cells.

TP, E-station, Schultz :smokin: :smokin:

I hope some of the A123 cells find their way into the hands of some sport flyers for testing.

[Ticidytoc]

I'll gladly test a set if you build them. :wink:

[ozace]

Matt , i would love to come and fly with you guys :hug: unfortunatly the 20000miles of sea between us is a problem :WOW

[Ticidytoc]

Ya, one of these days I'll have to come there and see what all the fuss is about. :wink:

I'm pretty tired of you being argumentative, all in all this is NOT the venue for personal attacks.
Consider this a public warning, forget the PM warning. Act with respect and maturity, or you will be removed from the 'active' memberlist.
Life is too short man, let it go...

[MrMel]

I dont get Gary's numbers to add up.

A123 voltage under load is 2.5v per cell.

15 x 2.5 = 37.5

37.5v * 565kv * 10T / 95T * 0.90 (efficency) = 2000 RPM at 100% throttle.

You need 15s Lipo (3.36 volt under load) to get 2700 HS.

OR

its a Z50-800 which is 780kv, that would give that type of HS.
