Well,

The topic pretty much says it.................

Has anyone tried these yet with results comparable to the TP 2100's?

Thanks,

Ben Minor

EDIT: I'll probably go with the TP's since I'll be able to easily keep track of the cell balancing, but I'd still like to hear of anyone's results with the JGF's

I got a couple of their 2100-3s's. They are thick cells and weigh about 40 grams more than the TP 3s 2100's. They will fit between the frame sides ok. They are 50% cheaper than the TP's. I didn't try them yet, don't think I'll like the additional 1 1/2 ounces.

Tronics cells (largest lipo maker in China) - research those and you'll have your answer, know for short cycle life in general.

I have used the JFG 2100 15C lipos in my T-REX 450XL with JGF 450TH motor, they run well and do not get hot.

I am not sure about the life cycle, but I was getting about 8 to 10 minutes with an 11T pinion running 100% throttle in idle up 1.

These times are for doing 3D and FFF flight.

Hey guys - thanks for considering the JGF 2100's. A few things that you should know. You will certainly get great cells in the 2100's. I did my homework on these cells before investing in them and they are selling very well with no complaints.

Some facts:
1) They hold 11 volts for duration then drop quickly below 9 volts.

2) They handle 30 amps exceedingly well - since this is how I like to fly and are the reason I can now move into much larger planes. They are perfectly matched to fit the T-Rex and enable crazy 3D on the 450 line of JustGoFly motors - 450F and 450TH
3) The report of low battery life was a test performed by the manufacturer when over amping the batteries continuously. Not sure why he would do this on his own packs since he could have easily done the same on the TP packs to show the final result. It is well known that when you exceed the rating of a LiPo you will shorten it's life. Fortunately these packs are rated at 30 amps continuous, so over amping shouldn't be an issue. I have been running 35-40 amp setups for a few months but will need a year of running before I can know their life since I fly with a bunch of packs. I have pounded some packs into the ground at over 100 mph on a Jet and wrinkled two of the cells and they still charge up over 2200 mah and provide full power.
4) Lastly - my experience has been that you guys want a great value. I understand that weight is a major issue, but the extra power of these cells easily compensates for the slight extra weight. We do put some extra weight back into your wallet though

So - all I ask is you do a fair side by side comparison of these packs to the TP2100's and consider the cost savings. I've done the research myself and carry only what I fly and am loving the extra power from these packs. The 2100's and 1300's were the best bang for the buck in the spread sheet calculations that I did comparing Amp per $, Amp per Gram, C Rating ... Then handed bags of money to a Chinese fella who took three months to make the packs and fortunately am extremely satisfied with the result. Tronics has great stuff, although very scarey sales methods. Fortunately I'm already white haired

I am always collecting information from customers - so I look forward to hearing what your experiences are with the packs. I ignore assumptions and heresay, but listen to facts.

Hello Vinnie.

I have made my first flight with those batts and 450th, 13t pinion, 315 wooden blades, the power is there, but as it is my first flight I didn't want to stress the battery too much.

As i said, i didn't stress the battery too much, but I have been astonished by the temp after the flight. It was difficult to feel the raise of temp with the hand!!!! To make sure, i made the approx same flight with a PQ1800XP, and the temp difference was more noticeable.

Now i need to make 2 or 3 more gentle flights with it befor i can go full speed, full pitch.

By the way, you get a killer setup with 450th, 315 wooden blades 15t pinion , it works, and works well !!!!

As for the weight issue, i agree with you, if the extra weight comes with good perfs under high load, then i will gladly take it.

Person,

I'm SURE I'd paid some for the name, but I'm also SURE the TP2100's work well. Been there, flown them on a friend's model. I was specifically cautious not to bad mouth the the JGF cells. I've yet to get a rec against the TPP2100's, but I immediately received several warnings about the JGF's. So.............I'm going to give this a month or few and then resurrect this thread. If the reports come back OK, then I'll certainly need a third or more pack by then. They're still heavy, though........

Oh yeah... I surely have nothing against Vinnie or his company, since I have one of his motors heading my way right now.

Matt, We ship everywhere - lots running JGF motors down under. Might as well make the trip worthwhile and pick up a motor too

Dr. Ben - thanks for cautious optimism. It takes time to build a reputation - I'm in no rush. I don't concern myself with negative reviews - as long as they are from someone who has tested and is reporting facts. I killed a new motor when I read that they pulled too high an amps and bought back the bunch I sold. So post what you know - as long as it's not a guess at the truth.

Pitounet - 450TH is amazing me and selling like hot cakes. Check out the videos:

Wing - Direct Drive JustGoFly 450TH - Yours Truly flying

Another Wing - Will Haney

450TH Helicopter Climb outs - Zoom

and last but not least
a 3 lb plane running the 450TH geared - Craig Thompson

Enjoy,
Vinnie

I can sure vouch for Vinnie. He's for real. I made a trade for motors with him several months back for my Real Flight G2. Everything he claimed about his motors was true and then some. I've even picked up a few more that people were selling in the meantime. (The 300 DF is nothing short of astonishing in a small plane.) Had I known Vinnie was selling Li-po's I would have tried one of his packs before I ordered a new TP 2100 Pro-Lite pack. I plan to move up to the 450TH soon. I'll get one of Vinnie's packs when I make that order.

I'll second that on Vinnie's (JustGoFly) reputation. He has ALWAYS backed his products with me and ALWAYS made things right if there was a problem. I have just about every motor he sells and have no issues or reservations about buying anything from him because of this.

I know Vinnies motor and lipos work very well;

450TH in my T-Rex
400DH in my Shogun
400DF in my Hummingbird 3D Pro

The power from these motors is amazing, I have used other motors in my choppers, but nothing as good as these, by far they are the best bang for the buck!

I have been using his lipos for over a year now, I have some of his older 9C cells and some of his new 15C cells and I am happy with both the price and performance.

Dr. Ben - Looks like I've thoroughly HiJacked this thread. Please don't let my buddies here keep you from posting factual test information. No worries about broken legs or anything - hahaha It's tough not being passionate about this hobby and I am fortunate enough to be surrounded by guys that know their stuff and keep me honest. I carried some 9C batteries for a while and from customers I learned that they were very good right up to the claimed max amps and poof they would puff. I expect a 20 amp rated battery to provide 25+ amps before blowing. The Tronics are all that and a bag of chips easily handling 30 amps and upto 40 amps for 60 seconds. I always push my motors and batteries so have been running the 2100's at 30 + amps for the past couple months without a puff and have crinkled a couple of the packs on crashes, with no ill effect. I think I'm repeating myself.

So I will return you to your regularly scheduled thread.

Hover - Maxx and Joe - thanks for the kind words !

TurboJoe - that G2 is still working flawlessly. I wish I could claim the same ;-) Still hoping it will improve my ability to fly my Shogun, T-Rex and DragonFly. Hopefully the pending snow will pad some of my abrupt landings

This is my third flight with this pack
Configuration

450th
315 woodies
14tooth pinion
Headspeed ???? (somewhere between 2600 and 2800rpm didn't really tach)
Tronics 2100 15c
Max pitch 10.5°
Throttle curv between 85 and 97° symetrical

This pack is MAD. It has alot of power, and i prefer it than my PQ1800XP. The heli is heavier, but you have alot more power. The pack is just warm after the flight.
Flight program :
- Several full pitch climbing until i felt it was a bit too high for me
- Tic tocs
- Flips
- Basic 3D stuff
After the flight, the pack just a little warm. I have never seen a pack so cool after a flight, even when i was just doing hovering with my mega. This pack is wonderfull!!!
The additional weigh is no problem considering the additional power on PQ1800XP

Now I have still to see if it keeps it's power remains after several cycles.

"Now I have still to see if it keeps it's power remains after several cycles."

Indeed. I've seen lots of good data on these packs when apparently fairly new. I'd like to see how yours are doing after 20,30.... or more cycles assuming your care for and feed them well.
