2200mah 3s 65C pack = 143 amps continuous discharge capability

1300mah 6s 25C pack = 32.5 amps continuous discharge capability

So lets say a 3s setup averages 30 amps and the 6s setup averages 15 amps. You are pulling nearly half of what the 6s pack is capable of but the 3s you are only pulling nearly 1/5th of what the pack is capable of.

In short, the 3s pack is being stressed less and will stay cooler therefore will last longer.

3s motors are designed to handle much higher current draws than 6s motors so they stay just as cool.

EVERYONE uses way too much ESC in 6s setups because smaller ones aren't available which explains the cooler ESC. Most people use 40-50 amp ESC's on 6s which is double what is required, if a 60-70 amp ESC were to be used on a 3s setup it would also run just as cool as the 40-50 amp 6s ESC on 6s.

The extra run time is due to the larger pack that people use on 6s, 1300mah 6s packs have the same energy as a 3s 2600mah packs, so if you want longer flight times on 3s just get a 2600mah pack.

60% of the time, it works every time!

Sorry Richard, but try a 10K Mah 6s in your 700 and let us know how it works out.

+1 to DTM and michalss' posts. I've been running 6s in my 450s for several years now. You definitely get less heat buildup with a 6s system as well as longer flight times because you are not wasting the power in heat. You also get less voltage/rpm drop through the flight.
Yes, you can get the same performance out of a 3s system. However, they run hotter, and, the 65c 3s bats I have lasted one season before starting to get a little soft. My 20c 6s packs are just now starting to lose the ability to hold their voltage to the end of the flight and they are over 3 years old now. ( and they were 1/2 the price of the 65c 3s pack)

If they did a 700 size motor designed for 6s I would!
You also get less voltage/rpm drop through the flight.
If a 3s setup was geared and governed correctly you would get just as consistant HS throughout the flight.

All I'm gonna say is put a 3s setup with a 2600 pack and fly it next to a 6s 1300 Heli and see which one flies better

I understand the theory and it sounds good one paper, but to me it seems like it would be way easier just to get bigger 3s packs, so there has to be some sort of advantage... I have had a 450 pro on 45c 3s packs, I now have a 450 pro on 1300 6s packs... My 6s being heavier flies soo much faster than the 3s so I just don't think putting a bigger heavier 3s pack is going to help

What were the setups on both helis? Motor, ESC, HS, governor or flat curves?

I've had a few setups, my mini protos was just 3s, but on 450 pro's I've had scorpion 6 with ice 50, Stock 3s, current is align 1700 with ice 50... All flat curves

I tried gov with the Scorpion 6 and it was either not enough power or the end of the flight the hs would sag...

I love high voltage anything... Show me a 3s 450 with a 2600 that can fly like a 6s and I will reconsider

If high current was efficient, they would make a 700 size 6s motor. It's not......... so they don't.

In a 450 size the inefficiency isn't so great as to make it impractical, but it's still there and a 6s system is still superior to the 3s.

I guess my only real point is don't knock it until you've tried it.

Sorry Richard, but you can, in a big way.

I stretched my Mini Protos a few months back, and also converted to 6S. I was flying it last fall with TP 3S 2250 65C packs, and it flew decent then. But even with these cheap Turnigy Nanotech 1300 45C packs (2X3S), this thing rocks out!! Far more power, about 20-30 seconds more flight time smacking it around, and a 20 degree drop in motor temps. The power is there, the efficiency is there, there is no denying the difference.

I'm using a HobbyWing 40A ESC paired up with the VBar gov. The performance is absolutely way above a 3S machine, even with high end TP 65C packs.

Have you seen Kyle Dahl's 450 video at 4000 rpm on 3s? I haven't seen any 6s videos as fast as that!

They don't make 6s 450's out of the box either.

I'm going with the kit+blades+YGE. Since the YGE was chosen by MSH to power the 3s setup, laws of physics/mathematics support my theory that it should be more than capable of handling a 6s setup.
1300 mAh 6s packs seem like the obvious battery choice. Motor will be swapped for the 6s Scorpion by MSH.
Now if only they would make a beastX with built-in Futaba receiver...

The MSH 60A is more than adequate. Heck, a 30A ESC will probably work just fine as well. The HW 40A I'm using at the moment has been working flawlessly for about 50 flights or so.

His video was fast because of 4000 hs... If he made a video with 4000 hs on 6s it would be just as fast, just more efficient and the lipo wouldn't be smoking after flight

How do you know his li-po was smoking after the flight? TP 2250 65C I believe which I know for a fact wouldn't be smoking after that flight!

Im sure 6s is slightly more efficient and maybe slightly more powerful but for the cost of the new motor, ESC and those hard to find 6s 1200mah packs I don't see the point. A larger 3s packs would give you the longer flights, would slightly increase power and be less hard on the pack. It would still be a lighter weight setup than 6s due to the lighter ESC.

I am going to use the stock ESC. I didn't have any trouble ordering 6s 1300 mAh packs. Do you want to buy a 3s motor ?

Sounds like you got a plan

First the packs are easy to find, second I know because I had a scorpion 6 setup using 55c packs, my setup pulled More amps than a 500 and I wasn't running 4k rpm, and my packs were hot... All in gonna say is find someone with a 6s 450 and try it... Then slap a 2600 on a 3s and see which one you like better

This hobby is all about personal preference, mine is 6s, yours may be 3... As long as we're all flying what makes us happy

I totally agree, I just like a good discussion!

Hopefully ill be flying my friends 6s 450 Pro on Sunday and if I do I will report back on Sunday evening. However his is FBL and is a Pro and mine is a flybarred Sport! I run 100% on mine and around 3900 rpm and he uses an ICE50 using governor at around 3700. His setup weighs 170g more than mine also.... not really a good comparison. If it feels to have more power and more consistant power throughout the entire flight then that could be down to the governor. If it flys for 30 seconds longer than mine that could be down to it being FBL and using 1300mah 6s packs which I know I keep banging on about are the same power and weight wise as 2600 3s packs, im using 2150 and 2250mah packs on my 3s setup.
