Okay, I'm not sure how to pose this question. So here goes.

6S2P vs. 10S1P. Discuss/debate !

Here's what it is. I just bought a T-Rex 600 with a hot NEU motor and a Jazz 55-10-32 ESC. Four 5S1P FP 3700's. I was wondering how cost effective the 10S setup vs. the 6S is. For the 6S, I see that 6S2P is the convention, for the extra amps that are being drawn. In this case, there's actually 12 cells total, as opposed to 10! Wouldn't there be some economy to a 10S setup as the cell count is actually less than the 6S2P? Or is the 6S2P only because earlier packs didn't have the amp output to cut it on 1P, so they did 2P to double the amps that could be pulled?

Are there 6S setups that can be made comparable to 10S setups (in terms of flight time and general performance) and then compared by their price?

There are some good discussions on the Freak. You should check them out. Personally, I own both 6s and 10s setups and to be honest, 10s is a much better way to go if you're really looking for performance. Although 6s is fun to fly, it doesn't have the raw power of 10s. Sure the 10s setup is a little heavier but does make it fly a little more stable. An alternative would be to go 8s which is lighter than 10s but more powerful than a 6s.

For me, when flying 6s, I always feel like I need more power. This is with very good batteries, 6s1P Thunder Power and Flighpower Evo 20s. You should also know that the performance standard IS 6s1P. The 2P vs 1P does not double the Amps. Usually the 1p batteries are higher performance than the 2P setups (TPX/FP vs Align for instance).

If you have the $$, then go 10s. You won't be sorry!

There is no comparison or question in the performance between 6S and 10S. The 10S will win hands down every day, more voltage, less amps, equals cooler motor with more power. The Neu 1912/1Y outrunner is the ticket on 10S, other good motors include the Tango 45-8, and Actro 24-4. Both are more expensive then the Neu though with questionable gains in performance.

The better question is do you go to 8S or straight to 10S. I was about to go 8S and looked at the cost difference and it was not a lot. Might as well spend the money one last time on batteries and jump to 10S.

So as long as we are on 10s setups, what is the best configuration for holding the batteries nicely. What frames or setups are you guys using/liking?

Funny thing, later last night I ended up on heli-freak and I found a good discussion on exactly this subject. I read how the 3700's are adequate in 10S because it just doesn't have to draw as many amps (hence cooler running motor and easier on batteries). It seems that you could have the same flight time on somewhat less milliamps too. Like if you had a 6S setup running a certain headspeed on a 5000 mAh pack, you might be able to get a similar flight time from a 3700 or 4200 at the same headspeed. That seems to be a reasonable conclusion doesn't it?

Basically, using 10S would allow you to trade cell size (3700 instead of 5000) and get the same flight time, and not necessarily more weight since a smaller cell size x10, is about the same as a larger cell size x6.

The other thing I like is I am going to be using two 5S packs, so it doesn't put all my eggs in one basket. Puffing a cell in a 10S pack is less convenient than puffing a cell in a 5S pack.

The motor in the T-Rex I bought is an NEU 1515/2y actually. Plus it comes with a Jazz 55-10-32 ESC. I can't wait to get it!

I'm running a Neu 1515/2Y with 2 5s batteries (and also a 6s and 4s). I have velcro on both sides of one of the batteries to make it into a brick and it sits in front of the heli no problem. I do like the 2 lipos better than having 1 big lipo. You'll really have a great time with it. It's a nice setup. Just know that the 10s setup is still heavier than the 6s setup but the power is still much better! I get a little more flight time with the 10s, about 5.5 minutes as opposed to about 4.5 minutes of hard flying.

I'm running the Rotorworkz HFX frame conversion on the Trex 600. It allows for the entire lower frame tray to hold the FP 10S battery length wise flat in the tray.

This is not my heli, but an example of the frame and battery setup.

I'm running the HFX frame as well and have the battery mounted on the front (2 5s batteries).

That isn't my heli, and it's very clean cause it doesn't have all the electronics mounted.

I will post pics of mine once I finish the build (10S lipo and motor come tomorrow), it's very clean looking!

Best frame for this particular heli as mentioned is the HFX, it allows for every lipo there is, 6S if you want or up to 10S stick and the CG is spot on.

...Once upon a time there were Nitros, flybars and frequency pins...

docjoe, you have the same motor as me. Actually, many of you might be able to answer this, regardless of the motor in question.

I happen to have three 4S batteries for my Lepton (FP3700s). And with my T-Rex 600 I will be getting four 5S FP3700's. So IF 9 cells is sufficient voltage (hey, its ALMOST 10S), it would be POSSIBLE to fly three 9S flights using my 5S + 4S in series. Running 10S I'd just be able to fly twice. And of course, if I bought just one more 4S 3700, I would have enough batteries for FOUR 9S flights! I'd like that.

I have 42 amp hours worth of high-rate AGM batteries (two 21 Ah's in parallel) in my field box so charging capacity isn't that big a problem. But obviously more charged and available batteries makes for a more convenient time. Before a trip to the field I charge up all my batteries from my power supply at home, so hitting the field with four flights ready to go I might not even want to field charge much.

Now the question is, does the 1515/2 motor (with an optimal pinion) fly well enough on 9S ? Do the other motors that are commonly used for 10S fly "almost" as well on 9S? If 6S is sufficient - some think powerful enough, and 10S is ballistic, I imagine that 9S is still quite lively...

9S should work. You may need to get a higher pinion to get you the head speed you need and the flight time might be a bit less than 10s. I would recommend that you just make sure that the 4S and 5s batteries have the same capacity and hopefully the same discharge rate, so you're not over discharing one verses the other.
