5s and 6s. Pros and Cons?

[diduhearthat]

I see most people use 6s BUT some use 5s and still say the trex500 performs.
Can anyone tell me differance in using 5s or 6s.I do not understand why a lower voltage is used and change the pinion.Is a lower voltage harder on the standard motor+esc OR easier?
For me i think the 5s system looks better.i can get cells easy and charge 2 packs at once,i am a novice by the way so basic flight for me.But do not want to go the 5s route if it is unproven,why do most go for 6s if 5s does work.

I have not flown 6s but I can tell you my experience with 5s 300 TP with a 15 tooth pinion. I get about 6 minutes of good flying with plenty of bat to spare. plenty of power. And the lipos are cheaper.

I have heard of some going to a 16 tooth pinion but can't attest to how they fly.

I would like to try a 6s to see the difference but i would have to buy one and don't want to do it. I don't see any reason to change right now.

I use 5s and get same as post below......for a beginner 5s will much longer flight times and a lighter batter (same mah) at a lower price. 6s has more pop and is used by most people and due to that the prices are similar to 5s

I fly 5S 3300 packs because of the flighttime. Flying moderate 3D I get around 7mins per flight using a 15T pinion. However, I'm currently using a 16T and I get a solid 6 mins putting back 80%. 5S works fine if you're not into "Extreme 3D" and/or looking for high headspeed.

i think finless says it ll with the power discussion sticky?

Hi,

The Outrage 6S 3000 mAh 25C packs provide the best power/weight ratio (and fit without tray mod). Just around 435 g, stay very cool, and provide a lot of pop yet a lot of flight time.

You can find one of the latest Bob reviews here on HF.

Best,
Frank

6s-pro- a little more voltage=little less amps for same wattage used. I think you would really see a difference with 8S from 5S.
6S-con- may cost alittle more and a little heavier.

or 12S, thats what i am planning to do now...

i got about 90 cycles on my 3 (6S 3000maH) outrages, so its getting to the time where i use them in my planks.

my 500l is due for a change anyways....

Stupid question: How can you get longer flighttimes out of a battery that has less Watts in it (5s vs 6s)? Or is it that with a 15T the motor power consumption is so much less that it makes up for the difference?

That is not a dumb question at all, the short and simple answer is you don't. I believe most people who go with 5s also run higher capacity packs (3000+), were the 6s users go with around 2500mAh. I know some people are all about flight time and cram large 6s packs in there.

Personally I think I am a bit of an odd ball. I run 6s 2170mAh, I get about 5:00 of sport flying and about 3-4 minutes when I really start banging the sticks. Which is plenty for me, I can't keep my focus longer than that anyway! I also enjoy the lighter feel of the Heli with that smaller battery.

I have four batteries for the 500 and and plenty of charging capacity (3 x Hyperion Duo = 6 chargers), which keeps both my 500CF and 600ESP in the air as much as I want during a day of flying. I prefer more but shorter flights as I feel the quality of the flying is better if they are kept short.

Nope, I just carry a BIG Marine deep cycle 12V 115Ah battery.

Well, you're not the only oddball out here. I'm with you. I like the way the heli flies with my 2200 mah packs, and I gotta admit, after four min. of adrenalin, I prefer to land, take a breath and put in a new battery rather than keep pushing my luck in the air.
