Hello Guys, tough days purchasing in HobbyKing directly. no stock, backorders, delays,lack of response and slow deliveries.1/3 of the TP price will not come without bumps.

do you guys know a shop in USAthat is stocking either Zippy, Rhino or Turnigy batteries? I mean the 5S 20C 5000 mAh we use in two groups for FAI?

i need a few JST-XH female conectors to male TP and some training packs

thank you!

F3Aunlimited will have a line of Lipo's that are going to be really good in about 2 weeks. They have been testing them all winter and the results look very promising. The will be more than the Hobby Kings but far less than TP's or FP's and should be a tad better and available here in the US. Look for the news on their website.
From the website:
3/30/2010

F3A Unlimited: We can now contirm that we will be selling flight batteries. Not just any li-po but the best performing batteries available today, made to our specifications and optimized in weight (585g per 5S-4900 pack) and performance for F3A flying. We have been testing these packs for months now prior to offering them, and our testers have been unanimous in calling them "the best batteries they have ever flown". Special intorductory pricing will be announced soon. The first packs will be arriving at the end of April.

fantastic news from F3A Unlimited... we'll wait then...

That is really strange, because this is what Hobby King writes about the Turnigy batteries:

The new number one in performance and price!
The new Turnigy Lipoly packs deliver full capacity at the said C rate.
You wont find a better deal in Lithium Polymer batteries anywhere!

Because I always believe that the marketing guys tell me, I assumed that Turnigy was the best. How could something else be better???

The difference is that the comments I posted were quotes from our independent F3A pilot testers and not from a marketing dept sitting in an office.

I had chance to see Chris tested the new battery from F3Aunlimited at Hollister a while ago. With the same Himax 6330-F3A prototype and APC 21x14. At full throttle, loading voltage of the new battery was ~37.8V, my Turnigy was ~37V, resulted to almost 200 rpm difference. Data tell everything.

Last year (September 19th) I tested my (then) new Turnigy 20C batteries, using a Hyperion E-meter:

Motor: Cyclon F3A with close to 400 flights
ESC: Jeti Spin 99, timing 10 deg.
Batteries: Turnigy 5s5Ah 20C (x2)
Propeller: APC-E 20x13
RPM: 6690
Current: 93.6A
Voltage: 38.1V

This was peak performance, after about 5 sec full throttle run. (Thereafter it is all downhill, of course. Didn't measure further down the slope. One of the big problems with posted data like this is that the test methods used vary significantly, and the results will also therefore vary a lot. If I held full power for 30 seconds continuously and then measured, the results would have been very different. There is no "Standard Test Method" established, so people including me, are quoting figures left, right and center and they don't always make sense. But those were my results.)

any feel for what the price will be on these compared to HK?

Correct me if I'm wrong but the Turnegy packs are 47 ounces. Ouch way too heavy for any of my planes to make weight. The new" Power Unlimited" packs from F3AUnlimted are going to be less that 42 ounces all up. Mike

Magne

Yes, I think that is about the weight of them.
I mold my own models and make the weight suitable for the equipment I use, so that is not a problem.
But if you use commercially available models, then weight might be a problem, depending on which airframe you choose.
It is certainly good that there will be more "budget" choices available, because the batteries make up a significant part of the cost of flying electric pattern.

Hey I've used the Zippy 5000 15C at 42 ounces very successfully so I get the cost factor very well. I've also used the Rhino 4900 20C's but the 46 ounce weight only allows use in practice.
The Turnigy lipo's are a great value and your lucky if you can use them. Mike
Sorry for the ounces reference I'm old school and have to think to hard to compute grams.

Mvelez

hello guys! I'll post my question again: is anybody stocking zippys or turnigy in USA so we do not have to purchase them directly form HK?

thanks!

Have any of you guys weighed those Hobbypartz Blue batteries? Just curious what the weight difference is between them and HK's batteries. I've been waiting probably 2 mos. now for a couple of sets of 5s batteries from HK.

I've been waiting on HK too. If anybody has a used 10s pack they would like to part with cheap. Please PM me. As a Sportsman pilot I don't need anything great. Having only 2 flight packs is putting a crimp in my practice sessions. Send me a PM if you have a pack at a good price.

Derek.Koopowitz

I just received mine today - 1242g... with their stock connectors on them. They are plastic. I'm since removed them and put bullet connectors on two leads... the other two are soldered together to make the pack a 10s pack. They are probably a little less than 1242g now. Pretty good weight for 5000mah packs that cost $57.

Mvelez

I have one battery composed by  two Zippy lightmax  5000 mAh 5S 20C wired in series in order to get 10S. fully wired and ready to fly, mine is 1246g

also have four packs (to make to batteries) stuck in HK a month and a half ago and no idea when are they going to arrive (still in backorder). if anybody knows when is HK going to ship i'd appreciate (i get no answer at my emails to hobbyking)

OhD

Mine weigh 1239 grams or 43.7 ounces.

I spoke to HK last night, you have to call the US 1800 number after 8pm or something like that, the timer in the customer service window will let you know when they open 9am teir time.

I ordered on 4.15 and they said it should ship out next week sometime... maybe. hahaha

So today I orderd a set from HobbypartZ.com

Based on my recent experience , you should get your order in about 10 days.

I placed an order with HK on 4-9 , was notified of it ready for shipment on 4-14 and it arrived this past Monday.

Hello Chuck! my finger is swollen from dialing that &%$&%## 1800 number. I have tried the US toll free, the direct china number, spain,gemrany, etc...

i am just waiting for my batteries anxiously because our qualifying tournament for WC muncie 2011 is on july and i need to practice!

i'll let you know guys when HK  has the decency of delivering the last batteries i'll ever buy from them.

see ya!

I think the issue is just with Hobby City moving to a new location. Many people have been using them, a lot, and not having these problems. I got all of my orders from them within 10 days so far, except for this one battery order.

That being said, I've only got one set of batteries for the start of this season [&o]
