Looking at the specs the 3S has different cyclic servos and 325 blades vs 360 blade on the 6S. What would be the advantage one over the other? I am kind of leaning towards the 3s since I think my charger will do better charging a 3S battery but I like the idea of 360 blades better.

Wouldn't I be able to take my current 450 heli motor and put it in the 6S and run if as a 3S instead. I'm sure it won't do 3D like it was made to but that is fine with me to start out anyway then if I want more power put a 6S battery and the motor that comes with it in.

My charger says it can charge 6S but I have a feeling it wont charge very fast. It is a cheap charger and I don't quite understand how it can charge a 22.2 volt pack with only 12 volts going into it. It does say it can have up to 18V input but I have now way of feeding it 18 volts. I only have one 3S pack and not sure it will fit on the new Trex 450l.

I know the thunder power 3S 70C packs fit. But go with the 6S setup
Your charger will be fine on charging 6S. Which charger do you have

A 50 watt charger with a 6S pack will charge at no more than maybe 2 amps. That will limit you to about an hour per battery to recharge, assuming something on the order of a 2000 mah battery pack.

The charger will probably limit to about 1.6 amps with a 6S pack. The charger will do the job, but will take awhile to do it.

The 12 volt input won't limit you, the charger will do what it needs to do, even with a 6S pack. You may want to find a more capable charger and power supply to go with it. They're not all that expensive these days.

The biggest 6 s that fits is 1350mah so yo are still around 1.5c charging. Aligns are 1250 or 1100

The 3s version is a much tamer beast and can be governed upto 3200 ish or you can run 100% throttle and get around 3500 rpm.

The 6s version can be governed upto 3500 ish and 100% throttle would be a no no or you will hit nearly 3900 rpm!

With the smaller blades and slower HS the 3s version will give much longer flight times.

60% of the time, it works every time!

I have been looking at getting a new 450 myself, but after seeing the video of the 6s version it is the craziest head speed I have ever witnessed. Trying to keep up with that insane head speed is more than I care to try to keep up with. I haven't seem a vid of the 3s version.

There are 2 things you could do to tame the 6s version, use the old straight cut main gear and 12-13T pinion or run it on 5s. hobby king has some Zippy K 5s 1200mah 25C packs which would do but they seem to be out of stock at the moment.

Personally I think that the 3s version will do for me. I can't get over just how fast the head speed is on 6s.

That is not 100% accurate. I was running my today at 3200. It was fine. Yes you might out the efficiency curve , but it runs fine. Very stable.

How was the tail holding in a full pitch (13 degrees) punch out or fast backwards loop?

With the tail blades being longer and the boom being longer maybe the tail behaves at 3200?

Well my is set to 12 deg. Punch out are fine had mess with torq setting a little. Hurricane and loops tail was sold. Now only thing don't like with the 3 GX is when I hit TH hold I get a bounce in on the tail. I think that is being caused by too high gain on A/E . Will rest it out this weekend
