I just like the clean and tiddyness of it. No mess, no oil, less viration and the best part is I can hear the blades more, which I LOVE!!

I wouldn't go anything past the size of the Trex 600 though just due that the cost of batts are way to high at that level. I have a glow 90 for the big power stuff.

The Rexie 600 I can take to work with me in my trunk and pop it out for a quick flight or two during my lunch break. I'd say from trunk to flying, the electric is ready to go in less than a minute (batteries are already charged) while the glow takes at least 8 mins to fuel and get all the junk out to start it.

Still though, the power and size of a 90 size is in a class of its own and its awesome.

Well you have to have about 4 batts to be able to fly as frequently in a day as you do nitro... Started elec here and went to nitro for that reason... also by the time you add up the balancer, the $$$$ charger to charge at more than 1C, etc... for me nitro was the way to go.. now when the batteries come a bit further along this will be less of a problem...

As to the mess, really I dont have a big mess with nitro... carry a jug with fueling suppies attached, glow heat and a starter... pretty simple once your into it and try to get organized... certainly now worse than taking hte chaging equip... needing something to charge from, then long cable to car battery charge outside of car... etc...

So overall its flying preference... I will say though too that used equipment is currently much less expensive than electric...

If you want more flight time, go for Nitro. Weight of a couple of 6S is more than a starter and glow driver. You also need more than 1 charger/balancer if you are charging at 1C. $$$.

I never flew nitro, getting fuel and stuff was a bit of a problem for me, besides I usually fly near home at empty open spaces so I had to go with electric heli. I can say everything is tolerable with it, including the battaries. Just solder yourself the pack and go for a higher voltage and lower C rating and you get very inexpensive packs. Many modern packs are tested to not ignite for whatever reason.

But what I don't really like in electrics are a few things
1. I don't like the ESCs that much. They cost some 200-300 bucks and require constant attention - oh not to overamp it, not to underamp it, will the lipo be overdischarged, will this spark on every connection destroy something, oh make it so the capacitors don't touch anything or they get loose. RF noise. And no brand works perfectly, every one has it's issues, starting from cutting from underload to not arming or whatever. On the other hand what I really like about ESC compared to nitros is that when there is no radio input the esc shuts off, so no chicken danse is possible if RX gets disconnected.
2. Charging these lipos take hours and if you do it in your living room and don't have a garage or something, the fans from chargers really buzz for like 1.5 hours. They say it charges in 1 hour, it never charges in 1 hour, because the volts and amps are changing while charging and usually it takes like 90+ minutes to charge the pack. You can't just decide to fly again, you are limited with number of lipos you have. Plust you have to replace the lipo in the heli and that requires rebalancing your heli. So it's not like with fuel: Hey let's fly again! Ok, fill in the tank, pre-flight check, and fly until you actually want to leave. With electrics your desire to fly comes second and the number of lipos come first. So it's not as enjoyable.
3. This constant attention to the lipos isn't fun at all. Oh do I set the correct parameters, and even if I did you constantly watch these lipos to not get warm during charging. It's like babysitting, pretty frustrating. Oh is the cell in blanace? Whatever. It's not like : Charge over night and go, you know what I mean? You can't charget them overnight.
4. You need several chargers each at 200, plus a DC power unit for like anouther 100+.
5. All those wires. Is 12 gauge good enough, what if I have only 16 and 3.5mm connectors, will it work? Yes actually.
6. Then if you solder the lipos yourself, the nickel plates tend to disconnect with time if you hanve't fixed them properly
7. Great connectors and wires cost themselves quite a bit and so on.

Then of course the model doesn't smell with nitro or fuel but it smells with lube. And you don't have to fiddle with the engine tuning and break ins, so if you bought a proven combination of esc and motor you are ok.

It's too much work.

But I never had a nitro so I can't really compare.

man , I been flying electric helis since 2001 and I never go threw those problems , ESCs never , buy the ones that are proven , and be done with it , batteries , no problems there , charge and go , yes it does take a few chargers and 1 good power unit that can run all my chargers , boy , sounds like you need to go nitro to learn what all the downfalls are with it , good thing I dont fly with you . just reading yours makes me think wrong stuff and I fly nothing but big electrics helis , 10s to 15s

All the pilots in my club who fly Trex600's have had a battery pack puff and die. So at $300 each thats makes it even more expensive. It would be nice if the packs lastest for 200 flights but so far doesnt seem to be the case.

I love the smell of glow fuel.

Fortunately I leave it up to the other people at the field to provide it for me. I'm selling my Raptor 50SE/Hyper/401 tomorrow to a friend and am getting rid of all my field support gear to go with it. Good Riddins.

I've now got a decked out TRex 450SE and a 600 and don't have to worry about the leaking fuel/mess in the car, I can go from parking to flying quickly, I get that turbine like whine instead of the 2 stroke sound and I get the personal satisfaction that I'm flying something that just couldn't have existed when I was younger. Being high tech (from the 611 gyro to the big scary battery/grenade) just adds to the appeal. My first heli was a first generation blue shuttle with a 4 channel AM airplane radio and a remanufactured gyro that actually spun

I actually liked the Raptor 50SE, the proof was just in the logbook: my electrics fly ten times more often.

Tyler.

You're missing my point entirely. There are a lot of things I can do to prepare my helis at home and not waste time at the field. I don't use a cordless starter or cordless glow and am quite happy not worrying if those things are charged or not. Of course the Rx pack needs charged, it's a must.

To each their own, don't read between the lines. I love both Nitro and Electric and am just happy to fly!

well If I ran a setup in my Razor like the TRex did , then I would have alot of swelled packs , thats where TRex went wrong , 7 1/2 lb heli and useing low voltage , how about you , I see you have a 10s trex , I bet its holding up good

Interestingly, a chap down our club recently *Invested* in a T-rex 600, he's done his math as well.
Turns out, if you treat thoes batteries well you'll get more cycles out of each pack than the equivelant £'s in tanks of fuel through a nitro...
I think he was reffuring to a 50 as well heh.
So its kind of like buying all yr fuel in one pack in one go!

The morral there would be treat your batteries well and you'll save yrself some monkey over fuel

But then again, its burning the fuel thats half the attraction to me
Wont catch me playing with electric *toys* heh.

-Jvr

Ps, saying all that, now i'm flying my hyper and flying more often, i can feel the niggle of having to buy fuel far more often...
When i crash though, 14 gallons dont get burnt.

I treated my lipos too well and one did still die after about 50 flights. It was only while hovering and under hardly any load.
That's the nature of the hobby. Electric heli's have their pluses and minuses. The flight time, having to worry about battery temp, and the replacement cost of the lipos was my concern. Also the fact that you don't get full power for the whole flight. Even on 10S the power was great for the first 2 minutes then dropped off noticably after that.
I never had a fault with my Trex600 and it flew great. Battery technology is only getting better. I had a Sceadu Evo 50 which flew exactly like my Trex600 did but with less power compared to 10S.
I found it a bit annoying coming down to fly and after 3 flights having to wait for the lipos to cool then wait a least an hour to charge them back up. I did have 2 chargers so I had wait a little longer to charge the 3rd pack. It's not really a big deal to carry a flightbox for a nitro, fuel up and go.

The other thing that worried me is storing 6 x 5S 3700Mah Lipo packs even in my garage. I used to charge them in a steel pot. The new lipo packs seem to be more temp resistant. So far from what I have seen locally nitro is still more economical than battery power. I am yet to see a lipo last for 150 to 200 flights.

A lot of people forget this.

But you CAN sell your batteries for 50% of the original price when you used up the better half of it.

You can't sell your fuel after you burn them...

If carrying a simple flight pack and cleaning your heli is to hard for you then why is having to selling a battery that much easier, nitro is cheaper and easier in the long run IMHO

Battery technology is the driving force behind electric helis.
The motor is here already, you just need a cheap light weight high discharge power source.

Battery is becoming better and cheaper day by day, while nitro fuels...are just nitro fuels (you can add scent too it? change the smell or something, but it's still just nitro fuel... )

Electric went from "cool science project, but what's the point?" to "It has more power than my Nitro!" in less than 2 years.

Give it another 2 years, this thread would be just funny to read.
In 2 years, the top end lipos we are buying now would be garbage selling at $10 each.

Some guys are field charging thier lipo at 2C and even 3C without problems. Thats charged in 20 minutes. Sort of alters the maths doesent it. lf you want to debate the fors and againsts lets do it with todays setups not last years. A year in E helis is like ten in ic at the moment. Just look at your mobile phones over the last few years.

Flybars. Who needs `em.

Yes we can charge at 2c or 3C too but it greatly reduces the life of the lipo. Yes I agree the technology is improving. Get the flight times higher, charge times much less than atm with no harm to the lipo, saver batteries, it will come with time. Also I have seen alot of Trex600 motors die. That get so hot, even my 10S setup the Z50 gets very hot.
