Just get both!...problem solved!!!!! I have 4 electrics and 5 nitros. The only thing that scares me a bit about lipos is the fire danger.... it only takes one quick short out and the puffing and flame show can happen...seen it first hand when my freind messed up cutting the positive and negative lead off a worn out lipo...he told me "while in my house" wow this things getting warm!.I remembered watching lipo fires posted on here before, had him take the battery outside and set it on my concrete walk way....within a minute it was creating quite the show....so you do have to be very careful with the lipos....other than that..... I love both!

I have electric, no nitro - but if I'd have space (and no people complaining around), then I'd go nitro as well (actually I would then have both) for those days I spend longer time on the field, I am 100% satisfied with electric, but one thing : you just cannot fly many times before re-loading.

- Using the car battery makes it broken (not usually made for high amps)
- if you take own generator it's also noisy
- if you take as many batteries to fly the whole day you most probably spend 1000s of $'s for this
- and finally when you buy separate battery (e.g. deep cycle), this is damn heavy to carry

The batteries are expensive yes, and they don't last forever (but well over 100 cycles if drained to 80% only), and that money is probably same if buying gaz ...

Again, this re-loading is a pain, especially my leisure time is not really every half-day one hour, but usually one day a week, but whole day !

I was going to stay out of this post but I changed my mind. I own a blade cp and a 450 XL and the cost for these batteries are fairly cheap. But after seeing the 600 in person and watching it fly I must say I am really impressed with its performance. I love the size and the convenience that goes with electrics but the cost of the 600 batteries are unreal. I have decided to go with a nitro for my next ship because the batteries for the 600 are between 250-300 dollars for a decent set of batteries. If you add that up your looking at some major dollars just for the batteries alone. For the cost of four batteries not including the charger and balancer I could buy almost 45 gallons of fuel. I don't think those batteries will last that long if you were comparing apples to apples.

Now if money was no object I would prefer to have the 600 but in the real world it is. Most people with bill and families will have a hard time justifying this type of expence. Now if the flight time could triple then the batteries would be worth it because you would not have buy so many to have good stick time. I'm somewhat new to this hobby and I love flying as much as possible and that's what my 450 will allow me to do. But if I was flying a 600 I don't know if I could afford to stay in the air.

I want a bigger bird for next summer to fly along with my 450, but I am not willing to spend 1500 for a setup and then 1200 for batteries. I think in the future everyone will probably switch over to electric for cost and environment, but we are quite a few years away before we will ever get to that point.

I think people need to not only focus on the start up costs but the costs of running once the inital costs are done. For example, nitro motors wear out, what does it cost to replace or rebuild the specific motor you have? How many cases of fuel do you use and how much does that cost you? Glow plugs and how often those go, what do those cost you, worse is what does that cost you if you are in a bad position to auto and it can not be done and you crash beacuse of it?

There are many things that seem to not be discussed here when comparing.....

I agree that their are many variables that go with this that is not discussed in this topic. One OS hyper motor is still cheaper than one battery. ESC burn up, Elec motors go bad, and in some cases the entire rig sometime catch on fire destroying the whole thing. I love my Trex and I want a 600 but I research this topic for myself and that's how I came up with my conclusion. I don't know how much fuel is used in a year for the average person, but i'm curious to know if it's more than three cases (6 in a case) a year. And how much for a case? And how much flight time per tank on a OS hyper 50? Maybe some one with more experience can anwser this.

Crash parts for some nitro machine are pretty expensive that I do totally agree.

Os 50 Hyper runtime: about 9mins.

Any crash on a good heli will be expensive, regardless if it's nitro or electric. I fail to see how nitro would be more expensive in a crash than electric

Fly both, but don't bet your pink slip on the 90!
I was also going to stay out of this one, but reality is what it is.

I fly both glow and electric on a regular basis and have a few battery packs so I don't have to charge at the field.

This past weekend I put in about 4 flights on each heli and enjoyed both.

Quote
I'll put my 90 nitro up against any 50 electric out there.

When it comes time to race, I put away the glow machine and get out the ole XeroG 600 EP. It is a Raptor conversion and in a time to climb, or drag race is much quicker than any stock, or modified glow machine I have ever raced against.

Check out this from the IRCHA Unlimited Class Drag Race Final held in Muncie Indiana this past year!

http://www.rcgroups.com/forums/member.php?u=19510

Go down the page until you come to the video files from IRCHA.

The two most notable machines out there were Warren French with a very fast, highly modified R-50, and Keith Wilson (Unlimited class finalist) who was flying a purpose built modified R-90.

Glow machines are still kinda fun to fly and quite honestly I like to see the smoke, but when it comes time to have quiet clean flying, or high performance flying, ELECTRIC RULES!!!!

Just my .02

That being said that is poor practice to be flying by a lipo alarm imho and not a wise decsion at all.
Explain why using a (properly calibrated) lipo alarm on an electric is bad practice, please.
you can fly solid with no interuptions so I am not sure what all this work is you speak of. Limited span.....I have over 4 lipos
Do your batteries recharge themselves? I have plenty of batteries too, more to recharge.
Oh that's right it is adding up isn't it, maybe even more huh? I think some of you better redo your math and perhaps do a little more DD on this... cheers.
If it was about the money I'd take up a cheaper hobby, like smoking crack.

I always wonder why the electric guys are so defensive and always feel they have to convert the nitro guys. Reminds me of bible thumpers!

I have both and could care less what others fly. Fly what you like!

Umm guys? I don't think the original poster wants to see us fighting with each other.

Smaller electrics are definitely there. Up to probably a T-Rex 450 size. (30" rotor, give or take) Beyond that, it is questionable. If there are no overcharges, overdischarges, or bad crashes, LiPos do last a while. (oh, and if you start with good ones to begin with...)

With nitros & gassers, you are financing your flying, with electrics, you pay up front, and only pay more when you crash or abuse the batteries. (and eventually wear them out)

because I had great success with the Trex 450 AND because I didn't want to deal with the tuning of a nitro engine.
Yeah. Cause tuning an engine is really hard!! (Not) I'd rather spend 5 to 10 minutes tuning a nitro engine than waste any time setting up a lously T-Rex when its just gonna need to be fiddled with to get it correct for many more hours.

The thing I like about the bigger nitro ships is that I set them and forget them. No more tinkering around with setup. The Rex is a complete waste of time in my book from setup to building. I can take 2-3 hours on the Rex and go over everything with a magnifing glass, go out side and get an awesome flight. Come back the next day wanting another awesome flight and its almost impossible. Always something to fix or tweak. A prime example of this is getting the blades to track.

And Ken J didn't make some of you see the light? wow, that was impressive vid and coverage, and that is just the tip of it...

By the time you scratch your a$$ between flights I have a lipo hooked up and on the go, it is no big deal, unless you are lazy I guess.....I can hook it up and walk away minutes before you have even hooked up your nitro, got your pump to work and worked out the bubbles in your fuel line etc..
Explain why using a (properly calibrated) lipo alarm on an electric is bad practice, please.
Common sense tells me to know how much I am pulling from the pack and to actaully fly by what the batteries performance is to date. I keep a log of my mah back into pack after each flight and monitor it, after the hundreds mark and beyond I will fly abit less due to the lipos dropping off a tad by rule. Flying by an alarm that you may not see all the time or hear is silly, an alarm on my radio or a cheap cooking timer on my belt that I can for certain 100% hear makes much more sense, and is just plain common sense. Anything else Rogan? I think that more or less sums it up for you. Cheers

Are there any 90 size electric birds on the market?

I want to invest in a bigger ship in the new year and could be tempted to try electric at the same time.

Open minded to try, the appeal of clean quiet flight is tempting but i'd need a good few lipos, which atthe moment for a rex 600 are about £150 a piece.

Hmmmm..........................

A little less electric fanboyism so I don't have to play devil's advocate with you, maybe? Also mix up a bit of irony with that sarcasm; I'm sure there's some kind of moral lesson to be learned from your preaching tone.

We aren't all as meticulous as others in keeping records. I had attempted to do just that and was flying with 3 batteries for my TRex. But somehow, I forgot to charge one of the batteries. Put it into the TRex and of course it took off OK but very quickly came to earth causing some destruction of the TRex and destruction of the battery.

Now, I know that is all my fault but it is something else to figure in on when you are looking at having 3 or 4 or more battery packs.

Being pretty new to electrics (I have a TRex), I'm very confused about size of engine & batteries (and ESC for that mater). It sounds like I need to get additional components to be able to measure what the current draw is etc.

With a 30 size heli I get an OS32 or 37 or similar engine. With a 50 size I get a 50 to 55 size engine. With a 90 size I get a 90 size engine. With a Gasser I get either a 23CC or 26CC engine (I think I've got that right). But with an electric there are all sorts of different engines with seemingly no standards around naming. Then, when I look at batteries, there are 3 cell lipos, 4 cell, 5 cell and 6 cell (and up) depending upon what I'm flying. Whereas with Nitro I just need to figure out whether I'm using 15% or 30%. Oh that means one jug of fuel to fly a whole bunch of different planes or helis versus different sets of batteries for each of what I'm flying.

If I take all dozen or so flying machines to the field, I take a jug of 10% Plank nitro and 30% Heli nitro. I then fly engines ranging in size from 32 to 160, 2 strokes and 4 strokes. If those engines were electric, I'd have to get at least 4 different non-interchangable battery configurations and I shudder to think what it would cost to get my large chipmunk up and running where I currently have an OS 160 2-stroke.

Hi BC Don,

You could buy a bunch of 3S 2000 mAh 15C LiPos and interconnect them with a series or parallel module. Series them, and the voltage adds, capacity stays the same. Parallel them, and the capacity adds and voltage stays the same. But you'd still have to charge them all, and that'd take a few chargers. Oh well, it's a thought at least.

I'm sure some of the guys do this, as the above-mentioned LiPos are pretty reasonable, and connecting them up is no big deal.

I must admit this is the lines i've been thinking down, i think i'll get a rex 600 to try electric and i can always double the packs up for 12s if i want to try something larger
