What flight times are you getting??? What is your setup???
Ron,
With the brand new batts. I have my timer set at 4:00 minutes. The last flight I had I went one minute past the four minute mark. That flight took 78% of the battery. I should be getting a 5 minute flight once I condition the batteries after the first dozen flights. I'll then set my timer at the 5 minute mark.

Anyways this is my set-up.
Furion6
SKY lipo 10s / 2-5s 40c 4400mah
Scorpion HK4035 560KV 12 tooth pinion
Kontronik Jive80 {mode4} 2150 hs
CGY750 fbl system
Futaba bls255HV cyclic
Futaba bls 251 tail
MB Rail 606 mains
EDGE95 tails soon to be 105
Futaba 8fg super

I'm not accustomed to the short flight times. I get 12 minutes on my 50 nitro. I do love flying the electric just because its a heli. Its a lot of fun. Flies a lot like my nitro helis just faster. Also no need for any type of collective/cyclic management. I tried bogging the motor. No signs of bogging.

I'm still not sure why guys are getting such short flight times with their E's.

My Whippy E - HKIII 4035 450KV, Align 5200mah 6S batts - gives about 7 minutes flight time on 12S with an estimated 1900 or so headspeed. I can't imagine the thing being underpowered when I have both batts in it, it's just violent from start to end. The batts come down warm to the touch and at about 50 to 55% remaining.

My 700E - Align 470KV, same Align batts - gives about 10 minutes flight time on 12S. Head speed is lower, though, around 1600 rpm.

On 6S both helis are flyable safely for 10 minutes each.

Does the efficiency really drop that much when running those nutcase headspeeds? Or maybe it's those brutal, electricity-wasting 50,000KV motors?

Yes head speed makes a big difference. Drop that HS down to 1900-1950 and your FT will rise for sure. Of course less power will be a downside but you should be used to that with nitros j/k Team MikadoUSA 480XXTreme, 550SX, 600SX, 700XXTreme, 800XXTreme!!

Well I dunno, with that 105... that thing is just nutcasery powerful lol....

The 6S experimentation I've been doing has been really revealing. In particular, why my flight times are actually longer with one battery missing on my 700's.

In fact, to rule out weight loss as a factor, for a while I flew my trex 700E with both batts in it like usual, but with them hooked up in parallel instead of in series. That gave me a flight time of close to 15 minutes, even with the same amount of weight in the machine.

So I suspect that the typical 700/12S setup is actually a lot further out on the bell curve in terms of efficiency than we may realize. Especially when you get into the really violent/nervous setups with 2000+ rpm headspeeds - it looks like a LOT of power is getting wasted on these 3D setups just to make the thing flip or hop or whatever guys are trying to make them do as hard as possible.

But even my Whiplash, which is designed to do just exactly that, becomes a very efficient machine when you pull one of the batts out. That's even with a suboptimal drive setup - a motor designed to run on 44v rather than 22. The single batt comes down hardly even warm and will safely last for 10 minutes....

I was -ish experimenting with this on my 700N before I augered it in a couple weeks ago. I was flying it around at about 1350 rpm headspeed looking at the fuel consumption, etc., of the engine even tho it was being lugged pretty good. So a similar thing may happen even on a nitro. A lot of power may still be being wasted there too with it all cranked up to a raspy scream....

You should try a stock goblin at the recommended 2200 rpm, 3.5 mins! Same head speed on my trex 700e gets 3:50! I'm sure it's those ridiculously long tail blades!60% of the time, it works every time!

Really?
I didn't mean to sound like a jerk. Or idiot.
heli-cuzz;
You are an awesome pilot, an innovator, and a leader.
I meant no disrespect in any way.
I like everything that flies from helis to rockets and everything in between.
I can spend more money than I make on Electric or Nitro. They are both great.
I love the smell of nitro in the morning.

Thanks
I'm really liking the electric now.
I've been hovering in my backyard with no nitro grass kill spots. I love my lawn so I stopped messing with the nitro long ago in my yard.
Anyways, all this hovering has been good getting back to the basics cuzz really needed it. LoL
I've been hovering for about 4:30 seconds only using about 30% - 35% of a pack, so guessing I could probably hover the Furion for about 8 minutes.

Also, parallel charging 6 packs in 30 minutes is sweet.

Rather then debate, I can say that flight times can and will be on setup and what YOU as a pilot actually use and need for power. A good friend who is basic 3D sport gets 11 minutes from their 600SE Logo on 4400mah packs. Another example is I hear alot about 10-12 minutes on a .50 nitro well..... I have a 55HZ, with OS powerboost pipe, stock tank on a 600N and I get 6:40 tops before I gotta worry There really is not a chance I can get over 8 unless I just hovered around and that is not going to happen, this is with 2050 Head speed. So how one can take sides or even claim flight times as it is all relative to your setup, your wishes and your own abilities etc... That is one thing that IMO is not argueable really and gets tossed around a ton in these debates. There is a HUGE difference between someone with mastered collective versus a stick banger and 3D beginner and a hover king to an accomplished pilot in respect to flight times on either side of the fence.

None of this meant to discredit the OP either, I am just saying all far too often these kinds of threads get littered with complete BS or by people with very limited knowledge and experience of one side or the other, nitro or electric etc and it becomes quite annoying lol...
...Once upon a time there were Nitros, flybars and frequency pins...

You can setup an E heli to go for as long as a nitro BUT you won't be able to fly the electric as hard and even if that is no problem to you it still takes far longer to charge the packs than it does to refuel the nitro!60% of the time, it works every time!

Depending on the setup

I am a big nitro fanboy and have 3 competition grade nitros .90 size.
Here in holiday i fly a 500 leightweight setup electric running on just 4s4000 35c
You can fly easy 1450rpm 12 minutes or 1650 10 minutes using 2200 mAh
You need 30 minutes to charge 3 lipos in parallel

So with 6 inexpensive lipos and a cheap charger ( Hyperion 1420 i ) you can fly uninterrupted.

The power of the bird is not insane but at least comparable to a 70-80 nitro in 5.5 kg bird

For FAI style flying and precision training a ideal setup.

Is there any data collected on the life time cost of motors vs engines to make this comparison even more complex? And new clutches?

GASoline
With the influx of these new gas engines, the argument of fuel costs has no merit. Unless you just leave your heli idle on the ground 24-7 and feed it gas with an IV tube. Batteries might be clean and neat but the cost up front is a honker. It is all about cash flow, buying a gallon of gas at 4 bucks and flying for a month until you can come up with another 4 bucks is a lot more logical to me. Like the dude from Aussy said "giggle and fly" (or something like that)
