I hope build that quad next🤞🏼

I’ve been very happy with this quad. Durable and easy to work on.

You gotta up that ESC to a 45+ amp and try the 6s 3inch demon :] running silly little 380 & 530mah packs.

You wouldn't need that much ESC for something of this size. The max I've ever pulled with 3 pitch props is 50 amps total and even a 25amp ESC would be able to handle that with plenty of headroom to spare (note that a 25 amp ESC is 25 amps per motor so actually 100amp total). I run 650mah packs, since I need to stay under 250grams total weight.

What size and kv are your motors? I run 1404 3000kv and on a 650 I easily get 7-8 min easily doing light freestyle. Any normal freestyle easily limits it's to 4-5min.

These are 1404 4600kv motors. I can get a bit over 8 minutes casually flying around but in a hard freestyle sessions, get closer to 4 minutes.

Why were they destroyed? Did you run them down below 3.5 volts before quitting that flight? Destroyed sounds like misued. I wouldn't think you'd do that, but people do tend to discharge way too far a lot. Also, you do know there's no such thing as high volt, right? It's a marketing gimmick. If a lipo can take more than 4.2 volts pure charge don't you think ALL LIPOS would be doing it? It's true. JB, and several others have said it before. Charging to 4.35v is just gonna make them not last as long as the others. Also, if you want great lipos for way less than other manufacturers, with amazing Blow Out sales, buy lipos from Hobby king. ...But, they have several lines of lipos, so you must be picky. The cheapest are just ok, but their best are just as good as any other best brands that receive all the hype. 👍 I bought 850mah 4s from them in the model right below their best Graphene top of the line lipos, and I got them for $12 and change each! Beat that! Lol And that's not a 650mah, it's an 850 and they are superb! 💯 One of their older blow outs, I got 800mah 3s graphene lipos for 6 bucks and change each. I bought 10. Incredibly great lipos too! Better than GNB, and graphene last and last. You need get on their email list, which they rarely ever send you emails from, so it's not filling your inbox or anything remotely like that. Then, sit back and wait for their Battery Blow Out Sale. Nobody comes close to their prices. Seriously! And with Australia pretty close to China, I'd think shipping should be reasonable. Certainly if you buy a bunch. And, at their now out prices you'll save a ton of you buy enough to make it worth your time. Obviously 2 lipos isn't gonna do it because the shipping will negate the savings. But, I'll bet mine were close to half what you paid. Just don't buy their cheapest line of lipos if you want killer quality. 😎🤘 PS I have two 3.5" sub 250g DJI digital quads. With those 850mah 4S Hobby King lipos I get over 7 minute flight times ripping it, and can get well over 10 minute flights cruising.

They either puffed or the IR of one or more cells was way higher than the rest causing the battery voltage to sag like crazy. I consider myself as having good LiPo hygiene, always charge at 1C, store them at proper storage voltage, and try to stop flying at 3.5/3.6v per average cell. Sure there are the occasional times where I lose track and they go down to 3.3/3.4. I suspect I just pull too many amps from these small packs and flying during the winter makes things that much worse. You are right, most companies just do this through marketing. Not much information out there but I did hear that GNB was one of the few companies that actually use a different cell chemistry for their HV cells. So far from the flight performance, I'm inclined to believe it. The cells are smaller, lighter, and perform as good if not slightly better than my normal non-HV cells. I'm not sponsored by them and bought these with my own dollars. I actually asked them if they wanted to work with me and no reply. LOL :) Which company was this? I'm on the pulse mailing list, they sometimes have killer deals but then the shipping to Canada makes them the same price as buying local.

@@Mangorille I thought you lived in Australia. HobbyKing has the Turnigy brand of lipos, among several others. So much better deals than Pulse ever comes up with! not even remote close! We're talking 30 - 80% off regular price which is a very competitive price already!

Dogcom hold but abit expnsive😅

You're not the first to suggest Dogcom but those batteries are quite heavy. For example, their 4s 650mah is 99g vs. 69g for GNB vs. 74g for Tattu R-Line.

Let me know what tou think of those gnbs

So far so good, but they have a higher internal resistance per cell than the Tattu and Pulse cells I've been using. They are a bit smaller and weight a few grams less for slightly longer flight times. The true test will be how long it takes before they either puff or have a cell with a way higher IR than the rest.

Then batts are garbage !

It's the use case as well. Lots of amps from small packs. I've never gone through batteries like this on my 5"

@@BrainDeadEngineering I do a couple of charge storage cycles on the charger when the packs are new. They don't overheat on flights, just seem to puff over time or the resistance of one cell becomes too high so the pack starts to sag too quickly.
