Best place for LiPo packs:

http://www.flightenergy.com

They even have videos of the Logo 20, electric Raptor 50 and Joker flying 3D for 15+ minutes each!

I use these packs currently and theyre pretty amazing!

When is flight energy going to start selling them? I've read "few weeks" for a few months now. Sent a e-mail and never received a response. Are they available for purchase now? What's the price breakdown?

The site has barely even been up a month - so they havent had "weeks" posted for "months" now

There will be cells and packs available next week they told me. However - these are the standard voltage cells and packs. They produce a slightly lower amount of voltage under load and will be mostly used for the slow flyer market.

The high voltage cells like Ive been using will be available the end of March. The delay has been because they are improving the cell design even further, beyond the packs that Ive been using. I cant imagine much more performance, but they said I should see even more improvement!

As soon as they have more packs in stock Im going to sell the rest of my 3000 mah packs and buy all LiPos. Im making the glow guys drool when I fly my electric Raptor 50 for 20 minutes of all out 3D with MORE power than a glow machine

Those guys always reply to email, but I know they had early problems with their mail server which has now been fixed. Drop them a line again and Im certain youll here back within 24 hours.

I am currently working a deal on a Logo, and I have been reading a ton in RR and ezeonemag about "charlie's" miracle packs. I got the impression that these were really Lithium Ions.

Are the the packs you are running Li-poly's? If so, Then I take it these are better than the Kokams?

How much C can you charge your packs at?
How much C can they tolerate in use?

What charger are you using for them?

Are they dangerous like Li-Ions?

I am considering running Li-ions, in spite of the danger. I know where I can get 3000 mah cells for around $15 to $25 for 2. I was thinking of running them in 2s4p for 14.4 volts @ 6000mah, to keep the packs at 4C in a Logo10.

I realize that these cells are dangerous. Any websites you can think of for the safe handling of these cells (charging, etc).

Cool. When I said I've been reading "weeks" for months now it's because I've been following it here and on ezone and universe. If you check posts I think you will agree that the term "available in 2 weeks" has been used over and over for 8+ weeks. I'm looking forward to them being available to the general RC'er. I'm saving now as I plan to go all electric this summer and get rid of my nitro stuff. I don't want to buy any Lipo's till I can see what Charlie has developed. I imagine most folks in/going to electric are the same way. Slow flyers are a different story - the options are wide open there with such low current draw (already good, known Lipo's for them - has been for months) Those of us flying heli's or larger/sport planes are the ones waiting. And nobody is going to drop hundreds for these batteries until normal RC'ers and trusted reviewers can get them and see how much is hype. Flight times are great - but I haven't seen anything on throwing a pack in a bone-stock Corona, EP, Voyager, Eco, etc... As far as I know, they'll only pull such great times in very, very expensive ships at the hands of professionals. Will they be worth it to the rest of us? Will they triple run times on stock brushed systems? If so I'd rather spend my money on good Lipo's than a brushless system 'cause I'm not rich. The Lipo's are cheaper and should give longer times than brushless alone.

Tree-top....a few things....

Firstly, the packs have been flown in the ECO 8 for 31 minutes (It was using a brushless motor, but otherwise stock, flown by an intermediate pilot), a Corona (Also brushless, flown by an intermediate pilot) for almost 20 minutes before a crash shortened the flight , many different Logo 10s for 15-25 minutes (By beginner, intermediate and even Gary Wright who is definitely an advanced pilot), and they will be flown this coming week in my Voyager E (Also brushless). Yes, they are all brushless - not out of neccessity to fly LiPos, simply by the choice of the owners who have used brushless for months on NiCad and Nimh packs because of all the benefits they offer over brushed set ups. Ther problem with "can" motors in these helis is that they simply cant handle the power of a 3 cell LiPo pack (10 cell equiv), and wont fly well on 2 cells (6/7 cell equiv). You cant argue with a brushless power system - you can get a brushless motor AND ESC for any of the above helis for $130-$200 that will fly them GREAT. Honestly, thats the first money you should spend before LiPos - that I know from past experience. Can you use can/brushed motors and LiPos? Yes, you can! It takes the right motor - for the ECO 8, it would fly awesome using a 3s4p pack with a Magnetic Mayhem ($22 Kyosho RC car motor). You cant fly for 30 minutes straight - youd need to break the flight into 3-4 shorter flights per charge. If not, the brushes and comm would melt

These same packs have also flown in "average" RCers airplanes like the E3D for 32+ minutes, a converted Magic 3D for over 30 minutes, and more in San Diego in front of hundreds at the Mid Winter Electrics a few weeks back. The list goes on and on - many of these tests have been my fellow pilots right here in Las Vegas. Most of them dont spend time on the net like us, but you can bet if they did, you would hear about!

Your thoughts that it requires "expensive helis" and "professional" pilots to fly these packs just isnt true. I can understand your frustration - but you have to understand that like anything new, experienced RCers get to try it first. Do you think "normal" pilots were the first to get the new Raptor V2 helis? No, guys like the Szabos who are experienced and sponsored pilots flew the heck out of them for weeks before they were available. Why? So TT could gain positive feedback from a well respected source and fix any potential problems. TT did their homework, and it paid off! Charlie is pursuing the same type of testing and feedback to produce a winning product line right from the start.

As for the "average" guy who flies larger e-planes (Larger than slowflyers) and helis sitting back to wait - theyre the first in line for these things! Ive seen the Flightenergy waiting list - they have dozens and dozens of pre-orders from "average" guys flying Coronas, ECO 8s, Logo 10s, Logo 20s, E3Ds, 12-14 cell sport planes, and it goes on and on. they actually have very few orders for speed 400 and slowflyer packs because they arent even offering them yet - theyre still in testing.

Fact is, guys like you are anxious, and that I understand. Im waiting for packs just as anxiously as you guys are! I have been lucky to test fly and get some to use for myself, but only a few. Im done with subC cells in all my helis - as soon as I can get more LiPo packs in a few weeks, all my 3000 mah packs will be sold on the Zone and here on RR - for a good bit less than what I paid.

Packs have already been shipped all around the country for testing and reviews by "well respected" pilots, and even many average pilots who frequent these forums - those reviews will be popping up shortly. And when the every day RCer guys start getting these things over the next few months, you can bet these forums will be flooded with info.

Its hard to wait - and its even harder to believe since you havent seen or flown them personally. But for guys like me and the hundreds of others who saw them 2 weeks ago in San Diego, and those around the counrty testing them, these are the real deal. Theyre the "no comprimise, more power, less weight and even better flight times than glow" packs we've been waiting for

If you dont want to buy any and wait - hey, thats completely understandable! Theyre pricey - even Im penny pinching and have been for months to have enough cash ready for when more packs do show up. But for me, I already dump a lot of funds into packs. I'll spend the same and get fewer packs, but now I get 3-4 times the flight time with a lot less weight many times, and even more power.

karakoram -



Which Logo are you looking to get?



Actually, the first packs Charlie built and tested were Lithium Ions. They flew the Logo 20 for 27 minutes!



The packs everyone uses now are Lithium Polymer. Same great performance, but the slightly different chemistry is safer than LiIon.



No one has even come close to these types of flight times and performance using Kokams. Today, Albig tested Thunder Power packs in his electric .60 sized Joker heli - he got 29 minutes. I dont think any Kokams could do that...



You can charge LiPo packs safely at 1C. For these 7800 mah packs, thats 7.8 amps! Problem is - not many chargers can charge LiPos at 7.8+ amps! Chargers like the Orbits can do up to 5 amps which is great, but in the next year Im sure we'll see chargers capable of 8 amps and really large cell counts!



The 7800s can take up to 4C continuous! In my RappE, Im pulling 30-32 amps for just about the entire flight (Even more in 3D in short spurts). The packs are barely warm after a full 15-20 minute flight These same packs are used in airplanes pulling up to 62 amps for shorts bursts!



I have a Ginzel Spectra, but cant recomend it since they arent currently in production. Some of the best chargers you can use are:

Great Planes Triton
http://www.greatplanes.com

SC2 from Bishop Power Products:
http://www.b-p-p.com

The newest Orbit charger software proves very promising for LiPos as well. This allows up to 5 amps and 6 LiPo cells in series! That can charge an entire 6s4p 7800 mah pack like I use in the RappE in around 1.5-2 hours. Over the next few months even, I think we'll see even more chargers with even higher charge rates!



No - they wont explode as LiIons can

< am considering running Li-ions, in spite of the danger. I know where I can get 3000 mah cells for around $15 to $25 for 2. I was thinking of running them in 2s4p for 14.4 volts @ 6000mah, to keep the packs at 4C in a Logo10.>

Keep in mind - the Logo 10 uses a LOT more current than 24 amps! We've flown a number of Logo 10s on the 7800 mah packs - most fly for 15 minutes, and some get up to 20 amps. With those flight times, current draw averages more around 26-32 amps - and in aerobatic flight they can spike up to 45 amps!

I think the LiIons could work very well, but I would suggest running more cells in parallel to better cope with those current levels.

Which motor do you plan to run?

< realize that these cells are dangerous. Any websites you can think of for the safe handling of these cells (charging, etc).>

I dont know of any specific web sites - but LiIons are VERY dangerous. They will explode in most cases if overcharged, crashed, or even simply dropped! Thats the reason for using Lithium Polymer. I crashed an 8s4p 7800 mah pack of LiPos in my Logo 20 a few weeks back. Heli was totalled (PCM lockout - arg), but the packs survived and will be flown again this weekend! Had they been LiIons, I may have lost my heli and electronics had they exploded. I actually got all my electronics back and they work fine - cant say much for the heli though

Hope all that helps!

THanks for all the great info (BTW, I am in Reno, and there are lots of anti-electric guys here!),

I am currently working on a deal for a used Logo10. My seller is waiting for his current buyer to come thru, but he isn't optimistic. If you know of a Logo10 for sale, please let me know. Please PM me your e-mail, and we can talk direct.

After seeing what you had to say, perhaps I will wait for the Li-poly's, and avoid the danger of the Li-Ions.

I have been surfing and surfing and learning all I can about various battery chemistries, and even learned about fuel cells.

However, I would like to get a Logo10 in the air soon, and so I am always looking at the practical side. I think the Li-Poly's you are testing are the nearest solutions. Someday, the fuel cell may replace all bateries, but not for some time.

The Logo 10 I am possibly going to get is equipped with:
Kontronik Fun 600-18 motor and Shultze 45ho ESC

Thanks for all the great info! It really helps to get info from guys like you that have figured out what works and what doesn't.

Charlie's Packs

Jason,

How will these packs stand up to flying around for 5-7 minutes and then letting them sit for say 5-10 minutes (while I talk with the guys at the field) and then fire them back up for another 5-7 minute flight?

Actually Matrix,they work even better that way!

If you fly an entire 15-25 minute flight straight, the power starts to fade near the end. BUT, if you land halfway through, and wait for 5 minutes, or even 5 hours,the power is every bit as good then as it was on the first part of the pack!

Its very odd to see it work this way, but it does. Its great with my Logo 20 which now gets 20 minutes of agressive power. I fly for 10 minutes, go fly other helis and come back to it hours later and fly another agressive 10 minutes!

My buddy has an ECO 8 that gets 31 minutes so he makes almost 4 8 minute flights each day with hours of breaks in between! Power is every bit as good on the 4th flight as it was on the first.
